The device has iron and notch discrimination, which is used to discriminate the metal by your decision.

  • Iron Discrimination

The iron discrimination comes with 40 segments so you can dial the discrimination to find the target and input the value to the iron discrimination by setting around 30-35, which is great for starting. On the contrary, if you set the lower value, then there are chances for missing the target.

  • Notch Discrimination

There are 12 discrimination segments in this part, and it’s quite easy to notch out this segment. If you want to operate this you need to just press and hold the ELIM button. And remain one thing, you can use this notch feature in custom mode, but can’t use in zero modes. More than a detector, it is great for coin shooting method, and you should carefully work with it while using it.

How to Choose the Right Metal Detector

Here we will discuss a few factors that you should consider while purchasing a metal detector.

First and foremost, be specific on your choice. 

Because you may need the ‘best metal detector,’ but the fact is it is not possible to find one like that. 

There are different types of metal detectors, and each one has its best model or brand. Also, every brand has its unique features, functions, and way of use. 

So, decide which type of metal detector you will need. Like, if you are more likely to hunt gold metals, search the best metal detectors for gold, and if you are a coin collector and need a metal detector for your job, search for the best metal detector for coins. 

In this way, you shortened the process of selecting the right metal detector. 

Your Experience

Are you a beginner or a starter? Do you already have experience of purchasing metal detectors?

If you are not the one who just started metal detecting, jump into the next section.

Otherwise, I am sure you are in search of the best entry-level metal detector probably for gold hunting, coin collecting, or else.

Don’t complicate your hobby by buying a machine that you don’t understand.

No matter if it is small, long, cheap, or pricey, any metal detector can detect the metals. Only their added functions and features help us to decide if it is a good fit or not.

As a beginner, you should have a budget between $150 to $300. Anything below this range will not agree as a detector.

If you are a hobbyist, then I don’t recommend you spend more than $300 on a detector.

There are detectors above $700 to $800 that are worth buy for the professionals.


As already said, the type of hunting you do or planned to do with a metal detector impacts the choices you have.

1. Coin and Jewel

Most of the hunters use a metal detector for hunting coins and jewelry.

The metal detectors under $600 are intended for coin and jewel hunting.

If you need a metal detector for coin and jewel, make sure you don’t go for very high-frequency like metal detectors for gold. 

Stay under 15 kHz.

Because frequency and depth shares an inverse relationship so 

If the frequency is high, the depth of how long the metal detector goes will low. The result, you lose coin-sized targets.

Avoid pulse induction or PI machines. These are built for saltwater and gold hunting.

2. Saltwater Hunting

For hunting in and around saltwater, you will need a special metal detector. But dry sand areas of saltwater beach will not require it.

If the area to be detected is wet or full of water, you will need a PI or multi-frequency machine.

Avoid single frequency machines for saltwater.

  • PI for Saltwater

PI machines are not for differentiating things. So if the beach area you are searching for is filled with trash and different items, choose multi-frequency machines.

Most PI machines are designed for diving, so they weigh high. These diving machines will require a shoulder harness to make you comfort and balance the weight.

The highest depth is the great benefit of PI machines. With these machines, you can hunt effortlessly even in high mineralized areas.

After all, it is not necessary to tell that you need a waterproof machine for the beach, as that is the essential quality.

  • Multi-frequency

The multi-frequency machines are best at the discrimination of different metals.

Unlike PI, you can use multi-frequency machines for all types of hunting.

Having less depth ability is the only drawback of multi-frequency machines.


Freshwater hunting is not as tough as saltwater. It just needs a detector that is fully submersible and has good discrimination.

Relic Hunting

All-purpose machines do an excellent job in relic hunting. 

Few features must account for an advanced metal detector for relic hunting. Check the below list if you need one for relic hunting.

  • Coil Size: Large (DD preferred)
  • Frequency: 10-20 kHz
  • Adjustable Threshold
  • Iron Audio
  • Ground Balance: Auto and Manual


Once you decided to buy a metal detector, you should search and know about different technology that comes with a machine.

Let see one by one.

  • Very Low Frequency or VLF

Very Low Frequency or VLF is the standard technology seen on most metal detectors. These machines come under $1000.

These single frequency machines are the best choice for entry-level detectors and highly used for coin, jewel, and relic hunting.

  • Pulse Induction or PI

All specialty machines have pulse induction technology. In hunting at saltwater and high mineralized areas, this technology performs well.

These machines can find all the metals even through salt, iron, and other minerals.

  • Multiple Frequency or MF

Multiple Frequency machines have highly seen in high-end Minelab detectors. These machines cost above $1000.

It is for the most serious coin, jewel, relic, or other hunters.

These machines can be used to detect all the metal objects in dry land and saltwater areas. It combines both VLF and PI.

Search Coils

Stock coil size is another important thing you should check when purchasing a metal detector.

Does coil size important?

Generally, coils are ranged from 6 inches to 14 inches. We can divide the size groups into three as Small, Medium, and Large.

Small Coils – 6 to 8 inches

Small coils are used to identify and differentiate the metals. 

For fast-moving water, small coils are the best because they have less chance of getting aside by the waves because of their lightweight.

Medium Coils – 8 inches

Most commonly seen coils in the metal detector are these medium coils.

Medium coils can cover more space than the smaller ones, and they are far better in identifying the smaller objects than the larger coils.

Large Coils – 10 inches

Larger coils are highly recommended for deeply hidden metal objects, and they can cover a large amount of ground.

The only concern is its weight. For long-duration inspections, it is a bit difficult to hold. You will need a harness if your hunting extends 30 minutes.

Circular Coils Versus Elliptical Coils

Standard circular coils cover more area. On the other hand, Elliptical coils can only serve smaller spaces, but they can be used in very narrow and tricky places.

Choose the coil based on the area to be detected and the size of the metals you are searching for (if you know already).

I know, now you have decided that the larger coils are the best, but it is not the end, we have to discuss it further.

There is no doubt that larger coils have high depth and cover a large area. But there are other things to consider, such as ground condition and mineralization. These two have a significant part in choosing a coil size.

As the large coils go better depth and search a large area, they have to work on more signals in highly mineralized zones that lead to false alerts, and then you will miss the targets. So you have to reduce the sensitivity. Thus you lose depth.

While a small coils search less ground and process fewer signals, you can maintain the sensitivity and depth. 

Smaller coils also best at discrimination so you can find multiple metal objects.

There are reasons why you should have different coil types other than soil type and ground mineralization. 

While you are searching in small areas, you need a smaller coil for better mobility. These are also called as sniper coils.

On the other hand, hunting at the beach, farm fields, or any open areas will need a larger coil. 

Coil Type

Though there are various coil configurations available, the most commonly used are concentric and Double D (DD).

  • Concentric

Most cost-effective option.

It is easy to pinpoint the target with concentric than DD.

  • DD

DD offers high depth than concentric.

It deals better with ground mineralization.


The sound and screen or VDI (Visual Display Indicator) are two things with which a hunter can identify the metal objects.

As for as we know, most of the hunters use sound for detection. But the screen has things like the depth of the target, the time, what is the metal or target, battery life, sensitivity and discrimination values, and many more based on the model.

There are detectors with and without a screen. Mostly, people like the ones with the screen. Only, few choose detector without the screen.

The detectors without the screen are identified as dig machines. It just has a knob and doesn’t tell what it thinks about the target.


We have metal detectors from different ranges of weight from lighter as a feather to heavier as concrete.

If you can do only limited physical activities because of the elbow or other bone problems or if you are just a beginner started hunting, or if you will hunt for several hours, I would recommend you to choose the lighter models. Fisher and Garrett are well known for their lightweight metal detectors.

Considering weight is a must especially if it is your first metal detector.

The Working Mechanism of a Metal Detector

The style, look, and design of metal detectors may vary between different brands and models but the way they work is the same.

Let see how a metal detector works.

Any metal detector has 4 main parts. 

Control Box

It is the heart of the detector that is placed with the power source. The control box is located at the top of the machine that is near to your hand.


Antenna otherwise known as a coil is placed at the base. It consists of two parts.

  1. Transmitter
  2. Receiver


It is the lengthy rode or tube to which all the components of the detector are attached.


Obviously, from the name, it says what it will do. It stabilizes the machine so that you can easily control and hold.  

Batteries are the power source of metal detectors. The electricity from the control box with the shaft is transmitted using cables to the coil. By this, a magnetic field is created. 

When you use a metal detector on the ground, this magnetic field will be placed over the hidden metals so the current flows via metals and turn it to the detector that activates the receiver coil.

After that, the receiver coils alert you with the ‘beep’ sound about the metal objects.

Few detectors have bell and whistle sounds for the alert but the process is the same.

Consider the Essential Terms of Metal Detector


Sensitivity is a feature or the ability of a metal detector that used to detect different metal objects even in high mineralized areas. Nowadays, most metal detector comes as default sensitivity settings based on the manufacturer’s instruction, but you can also adjust the sensitivity based on the ground condition. This feature will help when you planned to hunt at different soil types.

Most of the starters think that having high sensitivity will provide them more treasures, but it is not true in all cases.

Yes, the high sensitivity will offer high depth, but it signals all the metal objects, even minerals and trashes. The metal detector will end up uncontrollable and annoying. So you need adjustable sensitivity that you can adjust it based on the ground condition and mineralization. 

Ground Balance

Metal content is present in all types of soils, so you can’t deny it while detecting metals. Sometimes they turn you against the detector. 

If your metal detector has ground balancing, it will detect the soil and find what types of minerals it has. Later, the detector avoids these minerals while detecting on the ground and give a signal to only the valid objects.

Metal detectors come with four variations of ground balance adjustment.

Preset Ground Balance: This is the ground balancing settings set by the manufacturer that works fine for most of the environments that have low or medium mineralization. 

Automatic Ground Balance: Modern metal detectors with automatic ground balancing will adjust itself based on the mineralization on the soil as you move around. 

Manual Ground Balance: If you have great knowledge of soil types and minerals, and you need full control of the detector on your hand, then you can choose manual ground balancing. Here, you, the user has to adjust the detector based on the soil type. Mostly for gold hunting, these manual setting is used.

Multiple Ground Balance: With multiple ground balance in a metal detector, you can switch between manual and automatic as per your need.


Discrimination is a great ability of a metal detector that saves searching time by differentiating different metals. If you set discrimination value as low, the metal detector will avoid detecting nails, coins, bottle caps, tins, trash cans, and other small targets. 

As the discrimination value increase, the metals a detector detects will decrease. So if you are searching for a specific metal or object, this mode will help you a lot with time and effort. It is a good choice to pick a detector with discrimination mode as you can utilize it if you want; otherwise, you set it off. 

Target ID

Target Identification in a metal detector allows the machine to tell you which type of target you are currently detecting. This alert will be provided in two ways, either Tone Identification or Visual Identification. 

Most of the recent metal detectors come with Visual ID, where a value called VDI number shown on an LCD screen to indicate the type of target. You have to familiar with these numbers to know what number probably means what target.

Machines with Tone ID will provide different types of tones based on the target. High pitch tone for valuable treasures and low pitch sounds for trashes or minerals. 

With these identification methods, the overall detecting, digging, and variating time will be reduced.

Ground Mineralization

You can’t simply ignore minerals and chemicals in soil and sand while using a detector.

The most problematic mineral while hunting treasures is Iron. It is conductive and turns the machine against you.

Iron exists in the soil for decades by itself. Most of the treasure hunters mention it while talking about ground mineralization. A metal detector can trace even a small mineralized thing as they are more sensitive. 

Then imagine, detecting or finding metal in highly mineralized soil or sand with chemicals. It is nearly impossible because the machine says ‘find.. find…’ every time it detects any mineral content.

Mostly, soil in Red or Black is old with high iron components that are forced by rain. It is merely tough to identify if the signal is for metal or mineral.

You can experience serious ground mineralization problems on the beach of black sand with iron compounds. 

To solve this problem, you just need a metal detector with auto or manual ground balancing and manual sensitivity features.

Like ground mineralization, another interference too affects the detectorists, Electrical interference. 

If you hear your detector singing, check if there are nearby power lines. 

Also, make sure the machine has enough space from their fellows.


It shows how depth your metal detector can detect coins and other treasured metals. Usually, lower frequency metal detectors provide better depth. 

Search coil size also matters. A large search coil will more likely go deep. 

For your easy understanding: In a depth of 1 ½ time of coil diameter, you can find coin-sized objects.

But it also based on the soil being detected and types of targets.

How Deep Can A Metal Detector Check?

A very common question asked by almost all the buyers.

As there so many factors invloved in this case, it is not easy to give a solid answer.

Some of the variables that can affect the accuracy of metal detectors are below.


If the soil contains more minerals, it is hard for a detector to penetrate as they are sensitive.


The objects that are grounded for years will have rust so they make strong signals even if they buried so deep.


Finding the large-sized objects in deeper water or ground in a large area is easier than finding smaller ones.

The larger the size of the object, the quicker you will get it.

Coil Size

Like the size of the objects, the size of the coil also plays a major role. Large coil detectors penetrate so well.


Rounded metals are caught more likely than lean or sticky objects.


Using the specified detector for metals makes the job easier. If you are hunting gold, then use the perfect gold detector than a random type.

Accessories You May Need With A Metal Detector

Having a metal detector is enough for detecting any metal objects but you may need extra tools and accessories after you found the targets. 

Dig Trowel

You get the alert to the target metals, now what you have to do? Just dig and get off the metals from the ground. For that, you will need a trowel. There are special trowels for metal detectors that are long and thin. But I would recommend the normal hand trowels. 

Sand Scoop

A utensil having a mesh that used for filtration. After digging sand or water, you have to drag the targets before you lose it to sea. A scoop with a pointed tip is best for rocky areas.


If you hunt for a long time or you use heavyweight metal detectors, having shoulder harness will cut off the weight and offer great balance. 


Wearing headphones while hunting metals avoid the noise from outside so you can focus on your search and more likely find targets. If you hunt at the beach, using a headphone will avoid sound from waves, wind, and people.


Pinpointer is not an essential tool for hunting metals but they make sense.

An external pinpointer is a great option if your metal detector can’t pinpoint to save the digging time and avoid guessing.

Pinpointer used to exactly locate the target. Your metal detector may lead the search to one or two feet, but it will be hard if it is a large area. In that situation, a pinpointer is much helpful.

Frequently Asked Questions About Metal Detectors

How To Use A Metal Detector?

After you powered up the machine, sweep the machine in front from side to side. You need to keep it close to sand or soil that the magnetic field will create and penetrate. Be careful that you don’t strike the coils on stones or rocks.

Do it steady and slow giving time to coil to detect the target and reach depth.

If you already have an experience of using a metal detector on your lawn for buried coins, metals, trashes, and tins, you know which moves of your machine will work out.

The metal detectors come with tone and visual identification. So be familiar with that VDI numbers and different tones. 

When you got that successful ‘beep’ sound, it is the time to pinpoint the location. Pinpointing will reduce the digging time.

Start digging a small hole without damaging the ground. 

After digging out your target, fill the hole and remove the waste then leave. 

What Is The Best Metal Detector for 2020?

From our research and review, we chose Garrett AT Pro Metal Detector as the best metal detector with overall features and abilities. It is an All-Terrain metal detector so you can use it for coin hunting, metal detecting in any ground, and beach.

AT detector comes with a manual and automatic ground balancing, adjustable settings, and quick recovery time. The price of this machine is entirely worth its features.

What Are The Best Brands for Metal Detector?

In no particular order, some of the best and famous brands that make from basic to high-end metal detectors are Garrett, Fisher, Minelab, and Whites. 

Any machines from these brands will be a good choice. 

Branding is essential, but it is not everything. So choose a metal detector that you can afford. All those brands offer machines from hundreds to thousands of dollars, so sure you will get one that suits you.

Should You Buy or Rent A Metal Detector?

If you just started metal detecting as a hobby, it is better to rent a machine. 

Mostly, you get the opportunity to try out different brands of high-quality metal detectors in a renting option. So you know better about various features and functions of metal detectors.

But as everyone says, owning a one is always the best choice.

Because each machine works differently, even if they are from the same brand, you will know how your machine will behave and which settings will work for specific soil types, targets, and metals as time goes and you use.

Though you have the user manual for coin or gold settings, features like mineralization and sensitivity, it will not match the self-exploration you do with your machine.

Where to Use A Metal Detector?

If you don’t have any location ideas already, you can start your first detection at your yard or lawn. You can understand your machine a lot when you tried in a comfortable place.

There are chances you or your family dropped something in the land. It does not matter if it is your new house; the land should be used so you can find valuable objects.

The second will be a beach as it is a mostly used public place. Playing games, handling things in slippery hands, keeping or taking coins in cold fingers will leave the valuables for you on the beach.

You surely need legal permission for both private and public beaches.

Parks are another congregate place that people often go. You can search around trees, benches, and places where the public sits and spend time.

For historical research in certain fields, you can use these machines. If you know what type of finds you are going to detect, it will be easier and make the job done quickly.

Churches are old buildings that must be respectful. There you have chanced to collect different coins under the trees and gates.

Following a footpath will lead you to a place with a human activity that offers valuable dropped objects.

Abandoned towns due to mining and transportation is a great place for exploring. Get permission from your Government if it needs to be safe. 

You are lucky if you live near historical fields or battle sites because you can get very interesting things like pistol balls, uniform buttons, and others used by our ancestors.

How To Troubleshoot A Metal Detector?

Here are the answers to a few questions that users raise while starting the machine.

Why is it not working?

Turn the machine on. If it is not working, you have to check the batteries. 

The high-end metal detectors come with the screen that shows the level of the battery, and it warns if the battery is low. 

Try after changing the battery. Always keep a spare battery with you. 

Also, check for loose connections.

Why I can’t read the display?

When the detector is in the shortage of power, the display will fade, so check the battery.

Why is it not signaling?

Check if the volume turns up or low.

Increase the volume and check without headphones. If it works, then the problem is with the headphone. 

Don’t check with high discrimination; otherwise, you will miss valuable signals.

Why is it too noisy?

Reduce the sensitivity if you were set it high. Make sure there are no powerlines, cables, or radio stations nearby.

Take a move from that place.

What if I dropped it on water?

If your machine is not waterproof, then it is a severe problem even it just got wet. It will surely damage the control box.

Remove the batteries and place the machine in a warm place and let it dry.

If it is saltwater, then you must prepare yourself to replace your machine because it will quickly corrode the sensitive parts of the device.

Why I can’t change the controls?

Once you switched on after taking out or changed the batteries, try a factory reset option.

Why I can’t move the needle?

It is because of static electricity. Use a damp cloth to remove it.
