Best Metal Detector for Coins Buying Guide

Before you start looking at new metal detectors, it’s good to have a basic understanding of how these things work!

Metal detectors use very basic principles to help you find hidden metals in the ground. Essentially, large coils produce an electromagnetic field. When those coils get close to a metal object, the electromagnetic field uniquely affects the object.

You see, metal is a highly conductive substance. That electromagnetic field creates an eddy current within the object. As a result, it creates it’s very own electromagnetic field. Your coin metal detector will pick up that second field, alerting you to the item below.

Of course, things get a bit more complicated than that. The technology used to power these devices has only gotten more complex in recent history.

Types of Detection Technology

There are a few different types of technologies used to find metal. Two of the most common are pulse induction and VLF technology.

VLF or Very-Low Frequency metal detectors are often regarded as the best for finding coins. They rely on different magnetic field polarities to find objects. The device itself produces a downward magnetic field, while the metal object underneath produces an upward one with reverse polarity.

The reason they are considered to be better for coins is that they produce continuous lower frequencies. Pulse induction devices create short bursts of current and rely on a reflected pulse to find objects. This technology is great for tiny objects buried deep within the ground, such as gold nuggets. However, it’s prone to missing coins that are closer to the surface.


The Trouble with Finding Coins

The truth is that most metal detectors can find coins. However, the issue that many people face when start coin shooting is efficiency and accuracy.

Let me explain…

Some of the best places to look for coins are areas that people once frequented. This could be old buildings, historic sites, old parks, beaches, and more. There’s a higher chance that these places could have old coins hidden beneath the soil.

However, there’s also going to be a lot of stuff you don’t want. Not only will you find random junk and trash, but you also have to deal with ground mineralization from centuries of settlement.

A standard metal detector may not have the ability to look past all of the unwanted junk. Instead of having the occasional “beep,” you’d be dealing with constant noise and distractions.


Must-Have Metal Detection Features for Finding Coins

The best coin metal detectors will have a selection of essential features that can improve efficiency as you search. Here are a few to look out for.

1. Notch Discrimination

One of the most beneficial features you can have is notch discrimination. This feature allows you to select certain parts of the conductivity spectrum to ignore.

Not all metals will produce a powerful electromagnetic field. Most detectors use the strength of the field to discover the object’s overall conductivity. As a result, it can determine the type of metal it’s made out of.

With notch discrimination, you can exclude certain types of metals. Most of the junk metals you’ll encounter are on the lower end of the scale, allowing you to focus your attention on things a bit more valuable.

2. Ground Balance and Mineralization Filter

Ground mineralization is your worst enemy when metal detecting coins. Small traces of metal in the soil can cause your device to go off regularly while masking targets. Ground balance settings overcome this problem.

With this feature, the device will remove the signals produced by minerals on the ground. High-end machines offer automatic filters. Though, manual ones work just as well in different ground conditions with some fine-tuning.

3. Pinpointing

Once you think you have found a coin, your job is not done. You still have to pinpoint it to dig it out of the ground.

Pinpointing features offer the precision you need to get closer to the object’s location. Usually, the signal will get louder or beep more frequently to let you know that you’re getting close.

4. Target Detection

While not always necessary, target detection systems can make your life a lot easier. Remember how we said that detectors use the strength of the magnetic field to determine it’s composition? Well, they use the same principles to suggest what the object is.

Some premium models go so far as to provide you with an outline of the hidden treasures. It’s a nice perk that can help you ignore even more junk.


Other Considerations

In addition to those features above, there’s a lot to consider when buying a metal detector for coin hunting. The following factors can affect the overall efficiency of your hunt and change the user experience.

1. Frequency Range

The frequency range of your machine will have a significant effect on the types of things you can find. Generally, a detector that can produce between 6 and 15 kHz is best for finding coins.

Many devices offer multiple frequency settings or let you adjust your settings manually. These options offer the greatest flexibility as you search.

2. Depth Capabilities

When it comes to depth, the size of the coil is important. Larger coils can penetrate deeper into the ground. But, you might sacrifice accuracy and efficiency the larger you go.

Most coin detectors can find items 3 to 12 inches below the surface. So, a medium-sized coil should do just fine.

3. Waterproofing

Do you plan on searching for coins around a lake or beach? If so, you’ll want to invest in a device with some fresh or saltwater protection. Water-resistant metal detectors are capable of withstanding splashes. However, if you want to go deeper and search under the surface of the water, you’ll need a completely waterproof model.

4. Weight

The weight of a coin hunting metal detector can make or break the experience. Take a look at a potential model’s design and weight distribution. Generally, units with arm cuffs and centrally located control boxes are the most comfortable to use. The weight is distributed evenly, reducing the load on your arm.

5. Controls

Finally, you should always consider the overall user-friendliness of the control box. Some metal detectors are very complex. They can be a bit confusing for novice detectorists who don’t know much about various settings.

On the other hand, simple controls may not offer enough variety for seasoned hobbyists. The key to finding an option that’s right for you is to match it up with your skill level and needs.


Conclusion

Finding hidden coins has never been easier with the right coin metal detector. Gone are the days of having to second-guess your alerts or digging up junk. The best metal detectors for coins offer some advanced technology to help you get past all of the things you don’t want.

Thanks to features like notch discrimination, ground balance adjusters, and more, you can set your targets high and stick to it. As you can see from our comparison chart, there are many great machines for coin metal detecting. Choose one and start searching!
