Buyer’s Guide

Are you still not certain with these reviews and need more information about metal detectors to purchase the best one for yourself? You will be pleased to know that we have also prepared a detailed buyer’s guide for you.

This guide lists all the important features of a good metal detector and also help you understand its functionality, so you know exactly what to look for and how to compare different units.

1. Discrimination

Discrimination is the ability of a metal detector to differentiate between one target and another. It should be able to tell you whether the signal you are getting is something valuable, like a quarter, or just trash.

It goes without saying that the soil is filled with endless rusty nails and bottle caps along with the valuable treasure, which is why this feature is very important. Having this feature in your metal detector will ensure that you don’t waste unnecessary time digging up trash.

Most metal detectors either have an auto-adjust feature or will allow you to tune out the trash manually. For certain things like relics and gold, you will not be able to choose discrimination, as it will want to dig up everything that is metal.

2. Ground Balance

With any soil you use your detector on, you will find that it will contain some level of metal, like iron. This could end up interfering with the detector’s ability to find jewelry, coins, or any other valuables. Having ground balance in your detector will allow it to bypass these minerals.

There are a couple of different variations of this on a metal detector. Many modern metal detectors will have an automatic ground balance that can detect and adjust automatically. Others may come with a preset ground balance. In this, the manufacturer will preset the ground balance at a particular level, which will work adequately in most environments.

With manual ones, the user will need to adjust the ground balance every time they use it for detecting. This may be a desirable option if you are looking to detect gold because of the changes in the ground conditions.

There are also metal detectors with multiple ground balance options, allowing the user to either select automatic or manual settings depending on their preference.

3. Target Identification

A great feature to look for in a metal detector is target identification as that will be able to differentiate between coins like a quarter, nickel, dime, penny, foil, junk, silver jewelry, or even the probability of gold.

The output for this could be a low grunt for junk items and a high-pitched audible tone for any valuables. This is often referred to as tone identification.

In most cases, target identification will be visual and will appear on the detector’s LCD screen. There will also often be a numeric value known as a VDI number that will appear on the screen. You will learn what exactly these numbers mean and also its probable targets.

4. Operating Frequency

The frequency on the metal detector is the number of times its signal gets transmitted and received by the metal detector every second. With lower frequency detectors, it can scan deeper, so they will offer an overall better detection depth.

In most general-purpose metal detectors, they will operate at lower frequencies. Detectors with a higher frequency tend to be more sensitive to smaller objects and gold.

If you are looking for specks of gold or smaller relics, then you should look for a metal detector that has a higher frequency. That said, know that these detectors are incapable of penetrating deep into the soil.

4. Sensitivity

The metal detector’s sensitivity is its ability to find metal objects from a distance. You could compare this to the volume control of a speaker. If it is set too high, then the sound gets all static and distorted, but if it is set to low, you will not be able to hear the sound.

Most metal detectors that come with sensitivity control will be marked with the maker’s recommendation. There will be certain situations wherein it will be necessary for you to lower the sensitivity.

For example, you will need to lower the sensitivity in areas that have a high mineral content and also those areas that are close to power lines.

5. Search Depth

All metal detectors are capable of searching for coins and other objects up to a certain depth. This is referred to as the detector’s search depth.

Metal detectors that have a lower frequency tend to offer a better search depth. What also plays a huge part in the search depth is the composition of the soil that you are using the detector on as well as the search coil.

If you have a larger search coil, then it will be capable of searching much deeper. Typically, you will be able to find coins that are at a depth of about 1.5 times the diameter of the search coil.

If you are making use of an eight-inch search coil, then you will be able to find coins typically at eight to 12 inches, for example.

6. Budget

If you are someone who is buying a metal detector for the first time, it can be quite confusing to select from so many options with a wide range of prices.

As a beginner, always look for an entry-level metal detector. There is no quicker way of becoming frustrated with metal detecting than buying a complicated unit that you just don’t understand.

Entry-level metal detectors normally tend to be under $200. Don’t go spending over $500 on a metal detector, which you aren’t even sure whether you will like using.

7. Weight

Some metal detectors are built as light as a feather, and then there are others are built like bricks and are quite heavy to carry around.

Weight is an important factor to take into consideration, especially if you suffer from shoulder or joint problems or even other ailments that will limit your physical activity.

8. Warranty

Always look for metal detectors that have a good warranty. Typically, most brands will offer a warranty that ranges from two to five years. Some brands offer a lifetime warranty; however, these tend to be quite pricey and are offered by only a handful of brands.


1. Can metal detectors find coins?

Every single metal detector on the market, whether it costs $100 or $1,000, is capable of detecting coins. Coins are metal, and metal detectors, by that logic, will detect metal.

2. How deep does a good metal detector detect?

If you are using a good quality metal detector, then it is capable of detecting at least six to 10 inches below the soil for objects like coins. With that said, several factors can affect this. For starters, it always begins with the kind of soil that you are using the detector on.

Additionally, when you are trying to detect larger objects, the right kind of detector is capable of detecting up to even 16 inches below the soil in ideal conditions. There are a couple of factors that could impact the depth. These are:

  • The size of the object that you are detecting. The bigger it is, the deeper it will be detectable.
  • The discrimination amount that you’ve set. If the unit is not set for proper discrimination or just unable to do so, you will be unable to find targets that are deep through the junk metals.
  • The metal composition of the target. Some will have higher electrical conductivity, such as brass, silver, and copper, while others, like stainless steel, don’t have enough.
  • The distance of the actual target to other larger metal objects in the same area.
  • The unit’s sensitivity settings. If this is set to an appropriate level, then even smaller objects can be found easily at a deeper depth.

3. Where are the best places to metal detect?

An ideal site for finding things with a metal detector will be in an area that is used by people over a long period. Other areas where you will likely find some interesting things would be an area that has been used by thousands of people in recent times.

Every region or locality will have areas of human activity and natural events, and these will offer great potential for detecting any metals. These areas may include abandoned sites, parks, beaches, gardens, churches, deserted towns, woods and footpaths, fields, and several more.

Other than just coins, there is always a possibility that you can find other valuable items, like lost jewelry, gold nuggets, and more. However, make sure that you are taking appropriate permission from relevant people for certain areas.

4. What’s the best frequency for metal detecting?

In the past, frequency on the metal detector was considered to be a big thing. However, with modern units, it has overcome the worries of the frequency with better circuitry and design.

Ground conditions will also dictate the frequency you need to use it, which is where having an automatic ground balancing can be advantageous. With that said, there are some basic kHz for successful hunting. These include:

  • A low-frequency machine at two to four kHz is considered to be the best for detectors for deeper coins.
  • The mid-level frequency at five to 12 kHz is ideal for relics, jewelry, and coins.

Most frequencies will easily pick up coins, but users tend to have the highest success when the unit is set between six to 15 kHz and, more specifically, eight to 12 kHz. Also, note that coins are made from different metals, which means that you will need to adjust your frequency for the specific outage.

5. Can I metal detect on public land?

Unfortunately, the laws are not very clear when it comes to using a metal detector on public land. What makes it worse is that every state has its own set of laws that tend to be very vague.

We recommend taking the necessary permissions from the right authorities on paper before you metal detect on public land.

It is also important to keep in mind that if you don’t have the necessary permissions to detect on a particular land, you could end up facing some stiff fines, misdemeanors, and, in some cases, it could also be a felony charge where you could serve some prison time. Ignorance isn’t bliss in this case. Hence, make sure that you are doing thorough research.

Final Verdict

There you have it. Those were the five best metal detectors for coins. Each of them comes with impressive features and will do a good job finding coins wherever you use them.
