Experts recommend taking advantage of a couple of setups for your metal detector. It will, in the long run, help you and your mineral prospects. So here are the best all-around metal detector setups you need for your metal detector units.
The performance of your metal detector plays a massive part in the results you’ll be getting. Whether you’re searching for mineral deposits or ancient coins, here are the setups you need to consider:
1. The metal detector frequencies
2. Sensitivity settings
3. Discrimination settings
4. Ground balance
Metal detectors perform in different capacities, but you can open up a whole window of possibilities by tweaking a couple of the settings offered to you. Not only that, but you may also increase the probability of your finds.
These are but some of the setups this article will delve into as you keep reading. So, you’re welcome to take a seat and get more information on setting up your trusty metal detector.
The Best All Round Metal Detector Setups
In layman terms, a metal detector consists of two parts:
A control head with buttons, batteries, knobs, and display.
A coil that creates an electromagnetic field that transmits and receives electrical waves.
Of course, the brains of the detector is located in the control head. “Sensing” the changes in the electromagnetic field is where the different brands use technical magic. Let’s get started on what you need to set up for your metal detector.
1. The metal detector frequencies
Metal detectors come in numerous formats. One such format that separates them from one another is the frequencies. There are multiple frequencies such as:
VLF (very low frequency)
PI (pulse induction)
ZVT (zero voltage transmission)
FBS (full band spectrum)
VLF and PI are the most common frequencies found in metal detectors. For those reasons, this article will only focus on VLF and PI. Here’s how they work.
VLF
Experts consider VLF or very low frequency to be pretty old. Why? Because they use magnetic fields. Nevertheless, old is gold, and experts recommend using VLF units when gold prospecting.
How does it work? The control box on the electrical unit generates an electric current. The electric current passes through the coil, and once it leaves the coil, it turns into a magnetic field.
The magnetic field produced by the VLF unit depends on the following factors:
The size of the coil
The type of coil
The frequency
External factors such as the environment
The magnetic field generated by the coil transmission vibrates at different frequencies. When you discover a metal object, the electrical current flows through the metal object. Now the object will create a magnetic field of its own.
So now you have your VLF unit and an object that have produced two different magnetic waves. Eventually, only the magnetic field from the metal object will remain while the other decays.
In terms of depth, the rule of thumb is that the lower the frequency, the deeper the signal will travel. The downside to this rule is that lower frequencies do not respond to small targets, whereas higher frequencies are more receptive to smaller targets.
PI
The second frequency is PI. PI refers to Pulse Induction. How does it work? PI units send and receive different pulsing frequencies from the ground.
How can you set it up? You can set it up by adjusting the pulse timing and the delay settings. This adjustment will help you determine the depth of your target as well as the sensitivity.
Experts do not recommend PI units if you’re into coin hunting.
They’re an all-rounder type of machine. They cannot discriminate between metals. When do you use PI units?
They are great for gold prospecting in highly mineralized soils.
They are also great for beach hunting.
You can also use them for relic hunting.
2. The Sensitivity Settings on Your Unit
When you buy a metal detector, it will come with a sensitivity feature. This feature allows you to either increase or decrease the sensitivity of your metal detecting unit.
The problem with sensitivity is that it’s one of the most critical features, but users misunderstand its value and functionality. How do they do that? The sensitivity settings allow you to toggle the degree to which your detector signals in response to objects passing through its magnetic field.
Best Metal Detector Setting
If you have a higher sensitivity level on your unit, you’re capable of finding smaller targets or objects. However, if you have a lower sensitivity level, it allows you to pass over unwanted targets.
It is true that the higher the sensitivity, the more the depth. However, the higher the sensitivity, the higher the risk that you will get phantom signals.
So, how do you attain balance? Experts recommend raising the sensitivity level to the point where your unit starts acting erratically. After that, you can slowly lower the sensitivity to an agreeable level.
Metal Detecting Tip: All those buttons and screens can seem confusing. Like sensitivity? Read the what’s and how’s in this article – What is Sensitivity and How do I Set it?
There is no way to remove phantom or false signals altogether. But dialing it down should reduce the risk of them occurring. It’s getting the best of both worlds. As you get more ad metal detecting, you can slowly start to increase the sensitivity level. It’s a slow and steady process that requires a lot of time and patience.
3. The Discrimination Settings on Your Unit
Next on this list is the discrimination settings. What is discrimination? Discrimination is the ability of your metal detecting unit to ignore any unwanted signals. At the same time, your metal detecting unit should only allow the targets you want to make a sound.
You get a null sound when you pass over a target metal that you don’t want to hear. That’s the essence of it. The majority of modern metal detectors come with the discrimination feature.
Best Discrimination Setting for Metal Detector
They also come with numerous options you can choose from for this feature like iron, tin, etc. If you come across a metal detecting unit without a discrimination feature, it’s referred to as an all-metal machine.
The downside to this feature is that the more you discriminate, the higher the risk of missing out on valuable targets like gold. Metal detecting units that are beginner-friendly have a discrimination level system.
How does this work? The higher the level of discrimination, the more objects you will block out when prospecting. On the other hand, the more expensive metal detectors come with a notch discriminator.
The notch discriminator allows you to block out specific metals without being limited by a scale. Nevertheless, nothing is perfect, and even notch discriminators aren’t a sound of reason. The best way to find out what you’re prospecting is by digging it up.
4. Ground Balance
Fourth on this list is ground balancing. What is ground balancing? Ground balancing is a feature that allows your unit to reject naturally occurring minerals in the earth as a target and instead use the earth as a baseline of sorts to find larger or foreign targets.
Currently, the ground balancing feature occurs in two ways:
Manual ground balancing
Automatic ground balancing
Furthermore, there’s another occurrence known as ground tracking automatically. You can find this feature on more modern metal detectors, and your metal detecting unit adjusts according to the ground conditions.
As the name suggests, it’s a manual process. The user has to adjust the unit as they listen for targets manually. The metal detecting unit relies on you to make the ground balancing. With every change in the environment, the user has to optimize the unit for ground balancing.
How do you change the ground balancing? Well, you can pump your coil up and down every couple of minutes. You can also pump the coil if you notice a change in terrain.
Automatic Ground Balancing and Ground Tracking
The second ground balancing method is the more modern option for metal detectors. The machine will do most of the calibrating as long as the user has done a sequence.
The sequence involves pumping the coil up and down, and the unit will do the rest. Here’s a step by step process:
Hold the ground balance button while pumping the coil up and down. Ensure to do this on some ground with no metal.
Stop when prompted by a detector. Some detectors will have two values: the detector’s current ground balance setting and the continuous readout of the ground conditions. When those values drift apart, you perform another ground balance.
The alternative to both of these options is ground tracking. A metal detector with the ground tracking feature will adjust according to the terrain. The downside to this feature is that you can find it with expensive metal detectors.

Metal detectors are pretty exciting tools. They allow users to find nails, ancient coins, sunken treasures, and gold sediments. Essentially, a metal detectors’ purpose is to find, well, metals. But can metal detectors find bullets?
Yes, metal detectors can find bullets. Metal detectors operate by sensing changes in the electromagnetic field around a metal object. Because bullets are made of electrically conductive materials like brass, lead and steel a metal detector will get a strong “signal” from a bullet. Finding bullets with metal detectors is how relic hunters and police recreate past events.
The average bullet consists of metals. There are other types of bullets, like rubber bullets. However, if you consider an average shell, it’s a metallic object by definition.
Nevertheless, this article will delve into how metal detectors find bullets. You’re welcome to sit down and learn more about the science behind it all.

Can Metal Detectors Find Bullets?
As shared earlier, metal detectors can find bullets. It all lies in the metallic composition of the bullet and the metal detector in use. Some Mid-tier and expensive metal detectors can find shells because they have target options on the screen.
Let’s give an in-depth explanation as to how that all comes about.
A Solid Bullet is swaged and cast in lead, or a single metal composed of either aluminum, zinc, copper alloys, or brass.
Bullet Jackets consist of either copper alloys, brass, aluminum, nickel, or steel.
A Bullet Core consists of heavier metal like lead or steel.
Bullet Coatings are typically copper, brass, nylon, or Teflon.
Lastly, the modern sabots consist of plastic. The sabot is a sleeve or adaptor surrounding the bullet and allows the user to fire it from a caliber.
The Different Types of Bullets
The NRA shares that there are five primary types of bullets. The bullets typically consist of the same material, but they tend to differ here and there. Nevertheless, here are the main types of bullets:
Flat-base bullets
Hemispherical bullets (usually found in Europe)
Boattail rebated bullets
Hollow or recessed bullets
Boattail-standard bullets
You might have come across rubber bullets and wondered if a metal detector can find one. The answer is a simple yes. Both the bullet’s core and jacket consist of metal, so a metal detector is likely to find one.
A metal detector can find any of the types of bullets mentioned above thanks to metal manufacturers use to make the bullets. Now that that’s out of the way, we can discuss the answer to this article’s central question: Can metal detectors find bullets?
Metal Detecting Tip: Without properly registering any ammunition before boarding a plane, a metal detector WILL find it. TSA Guidelines
How Do Metal Detectors Find Bullets?
There’s a science and historical aspect to how metal detectors find bullets. You can try asking yourself how does law enforcement find missing bullets? Well, they use specialized metal detectors to find bullets in strange places like forests or grasslands.
The term specialized refers to high-quality metal detectors suited to finding bullets in criminal cases or the like.
The History of Metal Detectors
Medical treatment is a major factor in the development of finding bullets. Just think of how many people have been shot, and treating the patient involves locating a bullet.
So, let’s go back in history – metal detector history, that is.
In 1874, a Parisian inventor, Gustave Trouvé, created a device to find bullets in patients. In 1881, Alexander Graham Bell (yes, the guy that created the telephone) refined the invention to locate a bullet embedded in President James Garfield’s back. Unfortunately, the attempt failed, and the president died from the gunshot wound.
Once people realized that maybe metal detectors were pretty helpful, they used them in World War I and II to locate land mines.
In 1931, Gerhard Fischer made a metal detector that consumers could purchase and use. Finally, in the 50s, metal detecting became a massive hobby and led to a demand for metal detectors. Since then, metal detecting has contributed to society, and you can find some of these treasures on display in a museum.
Metal Detecting Tip: If you really want to dig into the portable metal detector science, read the patent that Gerhard Fischer filed – find it here – Portable Metal Detector
So, you can now understand that initially, inventors created metal detectors to find bullets within patients and for physicians to remove them. The theory and practical part worked, but it only gained momentum in the 50s due to increased hobbyists.
This explanation was the historical explanation to answer the question: can metal detectors find bullets? Now it’s time for the more modern scientific aspect of how metal detectors do it.
The Discrimination Feature on Metal Detectors and How It’s Used to Find Bullets
Before buying a metal detector, you ought to have educated yourself on the features of a metal detector and how to use one. One of the essential features is the discrimination feature.
A discriminator is your metal detector’s ability to ignore unwanted signals and allowing only the wanted signals to make a sound. So, if you’re looking for a bullet, you could focus on specific metals. Bullets mainly consist of lead, so that you could choose lead as your target metal.
Discrimination on a metal detector
Another example, you can think of nails. The majority of nails consist of iron. So, if you don’t want to find iron, you can silence your metal detector whenever it passes over an iron object. You can do the same with bullets but vice versa.
Since you prioritize lead, you can silence all the other metals and let your metal detector make a sound when you’ve come across a lead object. Different bullets consist of different materials; you need to have some backstory on which type of bullet you’re looking for, what material it consists of, and the caliber that shot the bullet.
However, there might be an instance where you ‘accidentally’ find a bullet or maybe an empty shell while prospecting. The possibilities are endless, but the discrimination feature can be both your friends and your enemy.
Another great thing about the discrimination feature is that it reduces the risk of ear fatigue. Many metal detecting enthusiasts will use headphones to listen out for signals. Some metal detectors also come with a loudspeaker option while also giving users a headphone jack. The possibilities are endless with this tool.
Metal Detecting for Bullets
As shared earlier, the majority of metal detectors have discrimination features. However, there’s a group of metal detectors that do not have the discrimination feature. These metal detectors are commonly known as all-metal machines.
As the name suggests, they give you signals of all metals when prospecting. They have their advantages and situations, but if you’re looking for something specific like bullets, experts recommend that you purchase a metal detector with the discrimination feature.
Not only that, but experts also recommend getting a metal detector with the discrimination feature if you’re new to the hobby. There are numerous metal detectors to choose from when you’re new to things.
Here’s a table on the different levels of conductivity and sounds to different targets.
TID
Noise
Target
0-10
Low tone or grunt
iron
11-25
Low to mid-tone
small bits of aluminum, birdshot, and other small bits of metal
26-50
Mid-tone
pull tabs, bottle caps, nickels, small gold rings, shotgun shells, and other low conductors
51-70
Mid to high tone
Larger gold rings, zinc pennies, Indian Head pennies, buttons, and bullets
71-100
High tone
silver, dimes, quarters, half dollars, dollars, and various large items
The discriminator tool may come across as a fantastic tool that will help you differentiate what you want from what you don’t want when prospecting. The unfortunate side to this assumption is that discriminators aren’t perfect.
The only way to honestly know what object or target you’re picking up is to dig it up and get it out of the ground. It’s the full proof way of getting things done the right way.
What Are the Most Common Things to Find When Metal Detecting?
From my experience, I find a lot of trash. Bottle caps, gum wrappers and pull tabs. In terms of finds with value – my number one is clad coins.
finding trash metal detecting
Metal Detecting Tip: The best way to get invited back to a private property to metal detect is to complete your search and asking the property owner where to throw out the trash you picked.
When consulting with detectorists with more experience than me, coins and jewelry are some of the most common things to find when prospecting.
Bullets aren’t as common, but there’s still a probability of finding a bullet while prospecting. Particularly when scanning battle fields or hunting camps.
What To Do When You Find Bullet While Metal Detecting?
Let’s say that you did find a bullet; what do you do with it? Well, on their own (without a firearm, that is,) bullets aren’t dangerous. The only problem comes when minors misuse them.
Not only that, but it’s challenging to set off a bullet without a firearm. The point is that the bullet will not explode if you do not involve a firearm. So what do you do with it?
There are three places you can go to dispose of ammunition:
Your local police station
Your local hazardous waste collection point
Local gun range
If you find a used and invaluable bullet, you can take it to your local police station, and they can dispose of it for you. But what if your local police station doesn’t do that?
You can take the bullet or bullets to your local hazardous waste collection point. You can put your trust in the training of the staff there. They know how to take care of hazardous waste items like bullets and cleanly get them off your hands.
On the other hand, what if you don’t have either of these options? Depending on your location, you can visit your local gun range and ask them for assistance. If none of this work, go back to the police station and request a way forward to properly get rid of the bullet.
Remember that bullets are not dangerous if they are on their own. On the other hand, when loaded into a firearm, they become a whole new object entirely.
What Not to Do If You Find Ammunition While Metal Detecting
Now that we’ve covered what to do while metal detecting and you come across a bullet, here’s what not to do in the same scenario.
Experts recommend that you should not bury the bullet. Why? Bullets consist of metals. Metals are not biodegradable materials. You can use gunpowder as fertilizer, but the rest of the bullet, the jacket, etc., are non-degradable.
Next on the list of things you shouldn’t do is throw it away in the trash. When your garbage truck comes to pick up your trash, it runs through a compactor. The compactor is capable of causing the bullet to explode, which isn’t safe for the people collecting your trash. Not only them but anyone else around the truck. Experts recommend avoiding your trash can altogether. There are other ways (mentioned above) to get rid of the ammunition.
Lastly, don’t soak the bullet in oil and water and then throw it away in the trash. Dispose of it correctly. The legend is that if you soak old bullets, the gunpowder will lose its spark. There is some truth to it; however, there’s no guarantee that the gunpowder will lose its spark.
Not only that, but you will also be throwing the uncertain bullet in the trash where it might explode when running through the compactor. It’s better to cover your bases before disposing of ammunition, and to choose to soak the bullet and throw it away isn’t a full-proof method.
It’s best to contact one or two of the places mentioned above to get assistance on how to dispose of your bullet. They in the future you’ll have the knowledge to get rid of it properly.
What We’ve Learned from Metal Detectors and Bullets
Metal detectors are capable of finding bullets because of the metal material used to make bullets. This feat is possible thanks to the original purpose of metal detectors and their current purpose.
Nothing about their mission has changed over time. Not only that but disposing of bullets is a responsible thing to do. Ensure that you take care of yourself and the people around you by disposing of the ammunition properly.
But if you find an old bullet that might be worth something, it no longer becomes trash but treasure. Ensure that you get an estimate of its value and work on whether or not you want to sell it or keep it as a token of your hard work while prospecting.
Old bullets can hold some value, so be sure to consult your local expert and get a price for your bullet. You have nothing to lose, and it can make for a great story.
Are You Interested in What Other Metal Detector Enthusiasts Are Asking? Here Are Some Extremely Helpful FAQs.
1. Can A Metal Detector Find Guns?
Guns are typically made of metal. So, a metal detector may be capable of finding a gun. The same applies to the majority of weapons. Most weapons consist of metals, so it’s pretty likely to find one with a metal detector.
2. Can A Metal Detector Find a Rubber Bullet?
Rubber bullets have a metal core and sometimes a metal jacket. So, a metal detector can find them.
3. Do Bullets Set Off Metal Detectors?
Bullets are capable of creating magnetic waves that can sound off metal detectors. They are metallic and are thus capable of setting off metal detectors.

How deep do metal detectors detect is a question that can be difficult to answer. The reason is that each device has a different level of depth. But one thing applicable for all metal detectors is increasing their detection depth.
To increase the depth of a metal detector, you can:
sweep the coil close to the ground
increase the sensitivity setting
reduce the discrimination setting
install fresh batteries
upgrade to larger coil
These factors affect how a metal detector detects targets.
Detector Guide: How to Increase the Depth of a Metal Detector
How deep do metal detectors detect? The truth is that there is no exact number that can answer this question since these devices are so diverse and exist with many capabilities. So, there are no actual numbers that tell the depth level that a metal detector can reach.
Additionally, the size of the object to be found affects how deep metal detectors can detect. However, you can always increase the depth level of a metal detector.
Increasing the depth of your device will allow you to find old relics and objects that detectors are not too sensitive and often miss. (source)
Sweep the Metal Detector Close to the Ground
One of the most common and easiest ways to increase the depth of your metal detector is to sweep the search coil the closest to the ground possible. This tip may seem like an obvious thing to do. However, many metal detector users often lose sight of how high they are swinging their coils. The primary reason is that they pay more attention to how they swing the search coil.
Metal Detecting Tip: “Low and Slow” is a popular saying among detectorists. I’ve seen folks scan right behind someone and find coins.
But the problem is that if the search coil is too high from the ground you are searching objects from, the shallower its detection level will be. So, when using your device, you need to ensure that it is not too far from the ground.
Increase the Device’s Sensitivity Setting
The higher the sensitivity of your metal detector the more it can help you increase the device’s detection. But it is important to note that the increase in the depth level will depend on the various circumstances. These circumstances include the soil type, target type, and the object’s size.
However, a metal detector’s sensitivity is a double-edged sword. Yes, it will increase the depth level of your device. But increasing the sensitivity can also reduce your device’s ability to identify targets.
Reduce Your Device’s Discrimination Setting
Most of the time, metal detectors give wrong readings to deeply buried and desirable objects. The culprit behind it is often your device’s discrimination setting that is set too high. A high discrimination setting affects how deep do metal detectors detect.
You can reduce the device’s discrimination level to the lowest setting that you can stand for a deeper detection level. Meaning you still should hear alerts for objects detected. Once you hear deep signals, you should examine them closely before you start digging. It would be best to watch out for a jump into the desirable range while swinging the coil.
With these steps, you will find deeply buried objects, not just nails buried close to the surface.
Fresh Batteries Provides Maximum Power
If your batteries are down just 10%, you could be losing inches of detecting depth. Example: With fresh batteries my older Garrett Ace 250 can scan reliably to 12 inches.
fresh batteries affect metal detector depth
With batteries down 1 level on the indicator I’m losing close 2 inches or more depth penetration.
Upgrade Coil Diameter
If your detector is capable of swapping out coils a bigger coil can increase depth. This does come with a trade-off. Your machine will lose some discrimination sensitivity. This may mean you dig deeper trash.
Metal Detecting Tip: If you can go metal detecting after a rain when the soil is soft, your detector will work more efficiently. The moisture will create a stronger electromagnetic field around the target. As a bonus, moist soil is way easier to dig.
How Deep Do Metal Detectors Detect: A Range Adjustment Guide for Beginners
If you are still starting to learn how to use a metal detector, you may need a guide in terms of the range adjustment. Thanks to the continuous advancement of technology, new metal detectors already come with range adjustment settings. If you know how to set these adjustments correctly, you will experience smooth and hassle-free hunting.
How deep do metal detectors detect will depend on how you adjust the settings. For this reason, it is essential that you have enough knowledge when it comes to this area.
Set your stock settings to low
The stock settings are likely one of the aspects of metal detecting that people often overlook. But if you are a beginner in metal detecting, the stock “turn on and go” settings can be an excellent place to start. This aspect is often set at a power of 60 to 70 percent. With such a setting so high, your metal detector will be able to discriminate out iron, foil, and other undesirable objects.
Many users turn their stock settings high and use the full power of their metal detectors to find out how deep do metal detectors detect. While that seems a good idea, using the maximum sensitivity of your device cam chatter from electromagnetic interference. Such is especially true if you live in areas with multiple cellular and wifi signals and substantial power lines.
That said, less is more in your detector’s stock settings if you are a beginner. Ideally, you only need to adjust the stock set to 7 of 10 (70 of 100). (source)
Pay attention to the ground balance setting
Not all metal detectors have a ground balancing setting. If you own a beginner detector, it may only allow you to use a factory preset ground balance.
But if you plan to go for an intermediate or advanced metal detector, you should never overlook the ground balance setting. Incorrectly set ground balance can lead to false signals and reduce how deep metal detectors detect.
Metal Detecting Tips for Ground Balance
Manual Ground Balance: This allows you to adjust the ground balance setting manually for you to hear the minimum amount of ground signals
Automatic Ground Balance: The detector itself will determine and set the best ground balance automatically. This option is more straightforward and more accurate than setting the ground balance manually.
Tracking Ground Balance: The device constantly adjusts the Ground Balance setting as it detects targets. This setting ensures that your metal detector’s ground balance is always set correctly. (source)
3. Use a metal detector with low frequency
The frequency is one of the factors that tell how deep do metal detectors can detect. Similarly, it is the aspect that tells how well the device can detect targets.
If you have a single-frequency metal detector, it will transmit high-frequency signals. Such a type of metal detector is ideal for finding small targets.
On the other hand, a single-frequency metal detector that can transmit low frequencies will provide more depth in detecting large targets.
Furthermore, there are also detectors equipped with Pulse Induction (PI). This device has more coils than single-frequency detectors. For this reason, it can send bursts of electromagnetic waves that bounce back as they hit a target. However, you cannot tell the difference between those targets that the PI detects.
4. Utilize the notch function
As mentioned, the higher the discrimination level of a detector is, the lesser trashy signals you will detect. But apart from this option, many metal detectors have a second way of doing that — the notch setting.
A notch setting is one way of removing a category from the detector’s adjustment range.
When you utilize the discrimination setting, you have to go from left to right to eliminate trashy signals one after another. But with the notch setting, you can bypass several categories. Meaning you can select what stays in and what goes out.
For instance, you can remove various categories, such as foils, and pull tabs while leaving in the 5c category. Such is an excellent option for people who use their metal detectors to detect coins and want to leave the 5c while removing the other types such as iron and 10c. (source)

How far can a metal detector detect is always a question for many. Most people who are not familiar with this device think it can detect very high depths regardless of the ground condition. However, several factors affect how deep a metal detector can sense metal in the ground.
The accepted depth a metal detector can detect is a relationship to the size of the metal detector coil diameter. So, a 12 inch diameter coil can detect 12 inches deep. Other factors such as: size of object, type of soil and the detectors sensitivity also contribute to depth of detection.
The detector’s frequency and discrimination also affect its ability to detect metal buried deep.
If you are new to using metal detectors, there are some tips that you can check out so you can use your device correctly. However, you need to remember that laws cover this practice, which you need to know before you start detecting and digging.
Finding Out How Far a Metal Detector Can Detect
A metal detector has a search coil that transmits an electromagnetic field into the ground to detect buried metals. Any targets reached by that electromagnetic field are energized, causing them to send their electromagnetic fields. Then, the detector’s search coil will then receive the retransmitted field and produce noise to inform you that it detected a target.
However, how far a metal detector can detect is always a question.
The truth is that there are no exact figures to answer this question. But several factors can affect the depth that your device can reach when detecting metals.
The size of the target detected
If your metal target is large, the metal detector can detect it deeper than the smaller ones. The reason is that larger metals have more surface area. For this reason, it causes more disruption in the electromagnetic field created by the metal detector’s search coil.
Additionally, the device can detect circular targets buried deeper as they also possess more surface area.
Type of soil
The type of soil you are detecting metal from can significantly affect the depth of detection. If you are detecting from mineralized soil, your metal detector will probably face some issues.
Soil mineralization happens when there is a high amount of metallic particles and minerals present in the soil.
So, if you are looking for metals buried in this type of soil, your detector will find it difficult to find what you seek. Such is because mineralized soil generates a magnetic response when metal detectors detect it.
One soil type leads to something called “Hot Rocks” which is highly mineralized soil.
Hot Rocks Metal Detecting
Moreover, how far a metal detector can detect from mineralized soil will depend on the soil’s mineral level. The higher the mineral level there is, the shallower your metal detector will detect.
The metal detector’s sensitivity
The sensitivity level of a metal detector depends on its manufacturer. For instance, the Garret Ace 250 has eight sensitivity settings. For this reason, it has better target precision and deeper reach.
But generally speaking, the size of the search coil directly influences how deep your device can detect. If your detector has a large coil, the more detection depth it will have. But it will also have less sensitivity to small targets.
The detector’s frequency
One thing that differentiates one metal detector from another is the frequency it operates at. The operating frequency is the number of ground-penetrating EM or electromagnetic waves the detector can transmit every second.
Metal Detecting Tip: I’m often asked about the best frequency for metal detectors so I wrote up this article – Best Frequency for Metal Detectors
Moreover, this factor also affects how far a metal detector can detect.
Manufacturers measure detector frequencies in kHz or kilohertz. So, if your metal detector states that it has a frequency of 7kHz, it can transmit 7,000 electromagnetic waves per second.
Many of the metal detectors on the market have frequencies ranging from 7kHz to 25kHz.
They also operate under either single-frequency or multi-frequency. Low-frequency detectors are ideal for detecting deeply buried, large, and highly conductive metals. Meanwhile, multi-frequency detectors are more sensitive to small and less conductive metals.
Discrimination
How far a metal detector can detect will also depend on its discrimination. This term describes the machine’s ability to differentiate metals accurately based on their magnetic properties and electrical conductivity.
If your detector discriminates against unwanted objects, it will detect metals buried deeper, such as coins. (source)
3 Tips to Using a Metal Detector Correctly
People often use metal detectors for two reasons — to find lost items or as a hobby. But if you want to find objects buried in the ground, you need to know how to use metal detectors the right way. Knowing how to use your device correctly will affect how far a metal detector can detect.
That said, here are three effective metal detecting techniques:
Apply Preset Search Modes
If you are not sure how to use your metal detector’s adjustable and advanced settings for maximum target detecting, the preset search modes are available for you. These presets have the right parameters to help you detect a particular object. You can also use them for metal detecting in a specific place.
You will often see these search modes labeled as:
Relics or Artifacts
Coin and Jewelry
Beach
Field

Create Your Search Profile
There are times when presets will not work well. Of course, manufacturers cannot always predict the suitable search modes for your site. Fortunately, some detectors allow users to create their search mode and save it for future use.
In the long run, you will develop your knowledge and skills about metal detectors. Once you have enough knowledge, you can set the best sensitivity, discrimination, and ground balance settings to improve your detector’s performance. Knowing these advanced settings can also enhance how far a metal detector can detect.
The Right Way to Sweep
Sweeping your metal detector is the best skill you need to master if you want to use your device the right way. Sweeping or swinging is the act of moving the detector’s coil side to side when searching for targets.
Metal Detecting Tip: Use the right sweep technique – means OVERLAPPING.
Slow Sweep and Overlap – Metal Detecting
Moreover, the best way to search objects using metal detectors is to sweep them slow and low. It would help if you overlapped your sweeping pattern to ensure that the detector is not missing any ground. Also, you should never tilt or lift the coil parallel to the ground as this action could affect how far a metal detector can detect. (source)
What You Need to Know Before Using a Metal Detector
While metal detecting is a mere hobby for many people, some laws cover it. These laws vary from one state to another. So, before you start digging, you need to ensure that the government allows metal detecting in the area you are in.
Moreover, Federal law does not allow metal detectors within the US federal properties and national parks. It is also important to note that you should never hunt for targets in historical and archeological areas.
Meanwhile, national forests allow metal detecting, rock collecting, and gold panning even if you don’t ask for permits. But the best thing to do is always to check and ask the office of the local park rangers to be sure.
In addition, the officials you need to contact to ask for permission before metal detecting will depend on the site. If you plan to hunt at a park, asking permission from local officials or park rangers will allow you to know your restrictions. Similarly, you need to get permission from landowners if you are planning to hunt on private property. (source)

One of the most common questions detector owners often ask is will a metal detector find keys. Of course, losing your keys is no doubt an inconvenience. So, having a tool that can help you find it can be a great help.
Fortunately, a metal detector can find keys. Most keys have metal conductors as their base, so a detector can quickly locate them. However, it would help if you had a preliminary idea about the location where you lost them.
Metal detectors can easily find your lost keys under the snow or even under dry leaves, dirt or sand. There are so many things that this device can locate apart from just keys. (source)
Will A Metal Detector Find Keys? Find Out
At one point, we all probably came back home after a long day and reached for our pockets only to find that we lost our keys. Not only is it frustrating, but it is also a major inconvenience, especially if you need to get inside your home immediately.
Searching for a lost key can be challenging if you have been to different places in a day. But suppose you suspect that you accidentally dropped it somewhere. In that case, you can use a metal detector to locate it in the area where you suspect it went missing.
Metal Detecting Tip: Learn about how deep metal detectors detect in this ARTICLE. The size of the item, electromagnetic qualities and orientation all play a factor.
Fortunately, a metal detector can help you during unfortunate situations. Most keys have metal conductors as their base. For this reason, they will react to the electromagnetic waves sent by your metal detector’s search coil.
Regular keys consist of brass as their primary material. Such a metal type has a mixture of zinc and copper, thus producing alloy. Both these metals possess high electric conductivity, making them highly detectable by metal detectors.
Looking for Lost Keys
On the other hand, which is the cheapest not-so-common type of key is also detectable. Finally, silver, which is among the most conductive metals, is the most detectable key material.
The bottom line is that regardless of the type of metal used to make a key, a metal detector will always be helpful in locating it. So, the answer to will a metal detector find keys is always a yes regardless of the key conditions. (source)
How To Find Lost Keys Using A Metal Detector
It is quite natural to experience a little anxiety once you realize that you lost your keys. However, it would help not let panic take over you as it could only worsen the situation. Becoming overwhelmed with panic is counterproductive and can hinder you from thinking where you last saw your missing key.
Metal Detecting Tips: If you don’t own a detector, guess what? Some shops will rent them. Read how and where to rent metal detectors in this article: Metal Detector Rental (How and Where)
So, instead of panicking, try to calm down and remember the places where you might have gotten your key from your pocket. Once you have an idea where to find it, you can proceed with the following steps.
Ok this might sound silly but, my wife will say a little prayer. It goes like this: “Tony, Tony look around. somethings lost and must be found.” I use this and it calms me down and usually the last place I look is where the keys will be found. 😜
Where to look for keys metal detecting
Narrow down the search area
It is natural to have a long list of areas to search for your missing keys. But if you look in those areas one by one, you will waste a lot of time and effort. For this reason, the best thing that you can do is to narrow down the search area.
Now that you already have an answer to “will a metal detector find keys,” the next thing you need to do is to retrace your steps of where you possibly lost your keys.
To do that, you can:
retrace the path that you took when you went home
try to remember all the detours that you made
think about when you think you lost the key
That said, the ideal thing to do is check your car to see if you dropped your keys there. You can also concentrate so you can remember when you might have lost them. Did you rush home after work? Did you go to other places like a restaurant or the grocery store? Remembering where you went can help you have an idea of where you dropped your keys.
Make sure that you did not drop the keys anywhere else.
The best place to start finding your keys is to try and remember where you last know you had them in your pocket. That can be at home, in your car, workplace, or even in a grocery store. This way, you will not have to spend so much time dragging your metal detector along grasses only to find that you did not drop your keys there.
Use your metal detector to find the keys
Will a metal detector find keys is already proven to be a yes. For this reason, you can use your device to start finding your keys on the places you suspect you dropped them.
If you do not have your metal detector, you can look online for people who would allow you to rent their unit for a day. Of course, a metal detector is expensive, so you cannot just decide to purchase one to locate your lost keys.
You can also look for a hobbyist in your area who will be willing to lend or let you rent their metal detectors until you find your keys.
Moreover, you should make sure to mark where you already searched for when you are trying to locate your keys. This way, you will not have to go over areas repeatedly. (source)
Sweep your detector one area at a time
Will a metal detector find keys? In some instances, the answer will depend on how you use the detector.
Think of sweeping your metal detector like you are mowing a lawn. Once you are in a particular search area, start sweeping the detector from one side to another while walking. Make sure that the search coil tilts at an approximately 45-degree arc in front of you.
In addition, the search coil should always be parallel to the ground. About three to four inches is enough in terms of the closeness the coil and the ground should have. Since you are trying to look for a key that fell to the ground, the search coil does not need to be in very close proximity to the ground. (source)
4 Things That Metal Detectors Can Locate
Metal detectors are electronic devices with a large search coil that sends electromagnetic waves into the ground to find metals. Once these EM waves hit metals, those targets will also generate electromagnetic waves, which the detector will receive. That way, this device can locate objects buried in the ground.
Will a metal detector find keys? Definitely. But apart from that, there are many other things that this device can locate under the ground.
Metal Objects
A metal detector can detect all types of metals. It can locate nickel, iron, copper, and even gold nuggets. If you own a general-purpose metal detector, you can use that to find buried items such as coins, jewelry, and relics.
However, metal detectors can also locate invaluable objects, like nails, foils, and small metals. To avoid getting signals from such types of targets, you can change the discrimination settings of your metal detector. The lower the discrimination setting is, the more efficient your detector will be in ignoring invaluable items buried in the ground.
Signals
If you have a very low-frequency metal detector of VLF, you will be able to pick up even the signals coming from ferromagnetic substances. That can include grain minerals mixed with iron in the sand or soil. The reason is that such mineral particles have conductive properties much higher than what a small metal has.
Metal Detecting Tip: The art of metal detecting is learning the sounds your machine makes. Subtle differences in tone and sharpness are clues to finding treasure. Good headphones make a difference and time swinging your detector
So, if you use your metal detector on mineralized soil, you will be able to detect signals even if there are no targets buried there. But if you are using your VLF metal detector on balanced ground soil, you will be more likely to locate targets more accurately. You may even find nuggets or flakes of gold.
Relics
Archeology widely used metal detectors since Fon Rickey, a military historian, first used them in 1958. These days, archeologists use them to look for artifacts buried underground.
However, Federal law does not allow the public to recreationally use metal detectors to find relics and artifacts within protected areas. The reason is that there are looters and artifact seekers who disrupt archeological sites with their hobbies.
Unwanted Targets
While it is exciting to think that metal detectors can find gold and treasures, they detect the most common objects are ferrous materials. That includes nails and other invaluable pieces of metal. Similarly, these devices can also detect non-ferrous materials, such as bottle tops.
Metal Detecting Tip: Learning how to set the discrimination will allow you to by pass gum wrappers, iron nails and pop top pull-tabs. Read about this article: How to set the Discrimination on a Metal Detector
To prevent your metal detectors from locating objects that you may not benefit from, you can change their settings. For instance, you can decrease the discrimination settings and increase the metal detector’s sensitivity to ensure that it will only detect targets that you can benefit from. (source)

One of the worst parts about having a niche hobby like metal detecting is not being able to find information when you need it. For any niche hobby these days, online forums are the best places to ask questions and learn from the people who have been doing it for decades. But not all forums are created equal, and it’s important to know which ones are worth your time and which ones are just trash finds.
1. Friendly Metal Detecting Forum (http://metaldetectingforum.com)
Friendly Metal Detecting Forums is the second largest metal detecting forum on the web with an outstanding 261,360 threads, 3,083,598 posts, and 52,465 members.
This is a classic forum in the sense that it is run on the vBulletin platform. As a result, the forum looks fairly modern, but still has the same recognizable statistics such as birthdays and who’s currently online. The Friendly Metal Detecting Forum has a huge user base of knowledge, but it still has the feeling of a small ‘friendly’ community.
Friendly Metal Detecting Forum
I’m always getting asked what equipment I use. I’ve been recommending the same solid metal detecting equipment for years.
My first metal detector was the Garrett Ace 250 (link to Amazon for current prices and reviews). This machine is still working great after 6 years. I keep it around for “group” treasure hunts.
I’m currently sweeping with a Garrett AT Pro Metal Detector (Link to Amazon for Prices). Since I bought my AT PRO Garrett has come out with a package that includes wireless headphones. Getting tangled up in a wire when your on your knees digging is a pain. Check out the Garrett AT MAX package with Z-Lynk Headphones and Pin Pointer (Link for great prices over at Amazon)
When it comes to digging two tools are a must have. 1. A hand trowel -I recommend the Lesche Digging and Cutting Tool (link to check it out) and 2. A sand scoop – the one I’m using is the CKG Sand Scoop with Handle (Link to Amazon for current price and reviews) A good sand scoop is a game changer for beaches.
Finally get a good pinpointer. I have an older Garrett Pro, but the newer version – Garrett Pro-Pointer AT with Z-Lynk is completely waterproof to 20 feet and hooks up to your wireless headphones.
The user tag1260 recently posted on this forum asking about what the proper way to cut plugs is. His question specifically mentioned not wanting to kill the grass and has already received 19 responses at the time of writing this (even though this post was just written a few hours ago. This kind of responsiveness and communal sharing of information is not rare at the Friendly Metal Detecting Forum and, in fact, is what this forum is known for. And also why this is the first forum on my list.
2. Treasure Net (http://www.treasurenet.com/)
Treasure Net is the largest metal detecting forum at the time of writing this. And while it also claims to be the original metal detecting forum it is definitely the most popular. The site boasts 500,000 threads, 5,400,000 total posts, and 120,000 members.
While this means that Treasure Net doesn’t have the same ‘friendly’ environment as a smaller forum, it also means that pretty much anything you want to know about metal detecting can be found from the huge base of knowledge which is being added to every day.
With this forum, if you can imagine it then there is probably already a few threads and couple dozen posts already dedicated to it and everything related to it. Some people don’t like this because there is no way to stay up to date with even a tiny portion of this gigantic forum, but if you like having more information than you know what to do with then this is where you should be.
Metal Detecting in the USA
Special Mention Website – Metal Detecting in the USA
If your looking for a wealth of knowledge and an experienced metal detector you MUST read Metal Detecting in the USA. J.R. Hoff has dedicated countless hours to build a resource that he freely shares with others.
The site goes into depth regarding civil war era artifacts and has extensive documentation about bullets used during the civil war. Since the history in the USA doesn’t go back thousands of years like other parts of the world, reading about the discoveries here in the USA is more to my liking.
Having the right tools to dig with makes a HUGE difference when Metal Detecting. Digging items quickly allows you to work more ground. I recommend three tools:
Lesche Ground Shark (link to Kellyco for price and availability) – Essential on EVERY outing for me!
Lesche Mini Pick If I’m in the woods cutting through roots and digging out rocks.
3. Canadian Metal Detecting (http://www.canadianmetaldetecting.com/)
The Canadian Metal Detecting Forum isn’t as big as the previous two, but it still has a total 601,097 posts, 54,969 threads, and 8,941 members. This forum is obviously directed towards Canadian’s; however, everyone can learn from the conversations had on this site.
There is a ton of good information about relic and coin hunting, and plenty of stories to go along with the tips and tricks you can learn from this forum. This forum might not have the size and appeal of some of the bigger forums, but it still has thousands of active users who are all looking to learn/teach about metal detecting.
4. Find’s Treasure Forums (http://findmall.com/)
Find’s Treasure Forum is self-described as the “internet’s most popular treasure forum” and is the third largest overall. This forum is built on the Phorum platform and is middle of the road as far as user experience in its current form.
However, at the time of writing this the Find’s Treasure Forum was moved to a different domain while a new and improved version is being constructed to replace it. After this new version of the forum replaces the old version the Find’s Treasure Forum will have one of the best user experiences of any of the forums on this list.
Another tip is… Find’s Treasure Forum is known for having a strict moderation and admin team, so it’s best to stay current with the rules and regulations which govern posts on this forum.
The Detector Prospector metal detecting forum is owned and operated by a man named Steve Herschbach and is primarily frequented by gold hunters of all sorts. In fact, I would go as far as to say that the Detector Prospector Forum is the best metal detecting forum when it comes to the subject of gold.
Detector Prospector Forum
The site is also very enjoyable to use as it is built on the Invision platform. The Invision platform is modern and easy to navigate, but, even if the site wasn’t so beautiful, it would still be worth your time for simply the awe-inspiring posts that one can often find here. I’m talking so many gold nuggets that you might start looking into moving to Australia.
A recent post on the Detector Prospector forum by user tnsharpshooter links to a YouTube video that shows him finding a large old gold coin as well as some other colonial finds. This one user has posted 5,835 times since registering 7 years ago, proving the dedication of the members found on this forum.
Warning: If your metal detector isn’t completely waterproof you might not want to scan beaches. When a metal detector manufacturers WATERPROOFS a unit it has been designed to keep SAND, SALT WATER and MOISTURE out. Don’t ruin your machine get a waterproof unit – I highly recommend the: Garrett AT MAX link to Kellyco
6. The Dankowski Metal Detecting Forum (http://dankowskidetectors.com/)
Thomas Dankowski (aka NASA Tom) is the architect of this forum, (Dankowski Metal Detecting)and it is the place where the best minds in metal detecting get together to talk shop. Moreover, these seasoned professionals are always willing to interact with amateur to try and pass on the information they have amassed over the years.
Of course, like on any forum, the occasional silly argument can be found without having to try to hard. But, in its defense even the silly arguments that happen on this forum are going to be well researched and intellectually sound. It’s only because the people on this forum are so passionate that can get caught up in the weeds of discussion so often.
7. American Detectorist (http://americandetectorist.com/forum/)
The American Detectorist Forum is owned by ‘Epi-hunter’ and ‘angellionel’, although an entire administrative-team work in conjunction to keep the forum operational. This forum is relatively small as it has 229,745 posts, 22,500 threads, and 3,807 members. But, don’t let this forum small size fool you, it is still built on the vBulletin platform and therefore it has a top of the class User Interface. Additionally, every month an award is given for the best relic, coin, and jewelry related find for a total of three awards that are given out.
This forum’s home page is actually separate from the main forum in that it is just a website that has a bunch of information regarding finds that have been posted on the forum and also articles that were written by members of the forum on tips and tricks to metal detecting. There are two metal detecting tutorials on this site as well.
If you’d like more articles about metal detecting check out the links below.
8. The Treasure Depot (http://thetreasuredepot.com/)
The Treasure Depot is definitely an old school forum in the sense that it looks a lot more like 4-Chan than Reddit. Despite the ancient User Interface, the treasure depot forum has over 1,000 topics, almost 5,000 total posts, and around 15,000 members.
A recent post by user John-Edmonton entitled ‘I really can’t stay (Baby it’s cold outside) I gotta go away (Baby it’s cold outside)’ describes going out on his first hunt of 2020. Even though it was -2 degrees Fahrenheit outside, John was still able to find a total of $3.96 dollars’ worth of change, 16 coins in total.
Relichunting.net is a niche forum which deals specifically with the art and practice of hunting relics with a metal detector. This forum has 6 sections, 120 subjects, and 28 categories in total. With only 84 users this is by far the smallest forum on this list, but it is also the most specific.
User FooserPaul recently posted about his finds from a 5-hour hunt. He found a Colonial Buckle, Crotal Bell, and a Fatty Indian Head Penny all in a 100-ft by 100-ft field. To me, this post perfectly captures the spirit of this forum in that it is filled with posts of completely unique finds which are really interesting to learn about.
