The Best Metal Detector Options


Metal detectors are devices designed to find metal buried under dirt, sand, grass, and even in bodies of water. Metal detectors work by creating a magnetic field around the electrical search coil, which spreads out to an average depth of about 10 inches. If conductive material is within the detector’s range, the electromagnetic signature of the material disrupts the magnetic field. The detector’s visual and audio alerts let you know you have found something.

Metal detecting is a great hobby for individuals or for families with children—some dedicated and skilled practitioners even pursue it as a professional career. The best metal detector for you will depend on how and where you want to use it, and whether you want a simple, straightforward model or one with lots of bells and whistles.

The Best Metal Detector Options


Types of Metal Detectors

Metal detectors are categorized based on how they are used and the items they detect. There are three main types of metal detectors: Very low frequency (VLF) detectors, pulse induction (PI) detectors, and specialty detectors.

Very Low Frequency (VLF) Detectors

Very low frequency (VLF) detectors are the most common and affordable types of metal detectors. A VLF detector has two coils: a transmitter coil that creates the magnetic field, and a detector coil that senses any disturbance in the field created by conductive materials.

In addition to being inexpensive and easy to find, VLF detectors are lightweight and durable, which makes them great options for beginners and children. This kind of metal detector is typically used to find coins, jewelry, relics, and other metal deposits. Though there are water resistant and waterproof VLF detectors on the market, pulse induction (PI) detectors are better for underwater metal detecting.

Pulse Induction (PI) Detectors 

In contrast to the VLF detector’s two-coil design, Pulse induction (PI) metal detectors have just a single coil. This one coil transits the magnetic field and detects conductive materials. PI detectors’ single-coil design is less affected by ground mineralization than VLF detectors, which is why it’s better to use PI detectors when searching beaches, rivers, or underwater (if you have a waterproof detector). PI detectors are not the best metal detectors to use in cities because they cannot discriminate between iron trash, like nails, and treasures like coins or gold. Another disadvantage of PI detectors is that they are more expensive than VLF metal detectors. Novice metal-detecting hobbyists may not want to make such a substantial investment.

Specialty Detectors

Specialty metal detectors such as multi-frequency detectors, gold detectors, and waterproof detectors can be either VLF or PI detectors, but they also have functions that enable them to execute specialized tasks.

  • Multifrequency metal detectors are ideal for professionals or hobbyists who enjoy metal detecting in a variety of locations. By changing their frequency settings, multifrequency metal detectors can be used in cities, on the beach, in rivers or lakes, or even in the ocean without needing both a PI and a VLF detector. The downside is that multifrequency devices tend to be expensive.
  • Gold metal detectors, as the name indicates, are designed specifically to find gold. This type of detector can be either a VLF or a PI detector, but has a higher frequency range than the other detectors. This higher frequency won’t set the detectors’ alerts off when they encounter salts and other minerals commonly detected while searching for gold.
  • Waterproof metal detectors run the gamut from those that have waterproof coils for searching in the shallows at the beach or in a river, to fully submersible metal detectors with waterproof coils and sealed controls that you can use while scuba diving. Make sure that a product’s “waterproof” designation—some units may not be submersible, for example, or others submersible only to a certain depth—is in line with the level of waterproofing you’re looking for.

What to Consider When Choosing the Best Metal Detector

Before choosing a metal detector, take a few minutes to think about the ways you’ll use it to find hidden treasures, and the features that will help you do this.

Target Type

Before you decide on a suitable product, think about where you will be using your metal detector and the types of targets you will be looking for. If you live near the ocean, lake, or a large river and you want to explore the waterfront with your metal detector, it’s prudent to invest in a product with waterproof coils or even one that is completely submersible.

If you’re headed to the desert to seek gold deposits, waterproofing isn’t as much of a concern. Rather, shop for a metal detector with a gold-specific detection range. For history buffs who seek Civil War or other historically significant relics, VLF detectors are often a viable option because they can differentiate between screws and coins. Some relic hunters opt for PI detectors, however, because they will detect most metal objects in an area, allowing the hunters to sort through all] the metallic bounty they find.


The discrimination of a metal detector is its ability to distinguish between types of material. For instance, a detector with good discrimination would be able to tell the difference between a coin and a bottle cap.

Having a detector with excellent discrimination saves you a lot of time because you don’t have to stop to dig up a target, only to find out it’s trash. Instead, the detector will only sound an alert when it finds an object that meets the selected criteria. For some relic hunters, metal detector discrimination may not be necessary. They prefer to locate everything and sort through it themselves, and not let a piece of equipment decide what’s trash and what’s treasure.

Ground Balance

Soil contains trace amounts of metals and metal alloys. No matter where you use a metal detector, these traces can interfere with a metal detector’s ability to locate coins, jewelry, and other metal objects. Metal detectors that have a feature called ground balance, however, are able to ignore these metals, effectively reducing false readings. There are four main types of ground balance:

  • Automatic ground balance will automatically detect and adjust for interference. The user doesn’t have to do anything.
  • Preset ground balance cannot be controlled by the user. The manufacturer tests and sets the baseline for detection, allowing the device to ignore small interferences that fall below this threshold.
  • Manual ground balance settings can be changed by the user, according to the target you’re looking for. Beginners who do not know how to properly set ground balance may find a detector with this feature challenging to use.
  • Multiple ground balance gives the user the option of setting the ground balance level manually, or leaving it on an automatic setting.

Target Identification 

Having a metal detector with target identification takes discrimination a step further. Instead of alerting you when there is something worthwhile to dig up, this kind of metal detector actually indicates what the object is, within an acceptable range. A metal detector with target identification can usually distinguish between jewelry, junk, gold, even coins of different denominations.

When a metal detector with target identification finds an object, the machine will either emit an audible sound or display a visual notification. The audible sound is typically high pitched for valuable items and low pitched for trash. The visual notification will display an icon of the assumed type of object. Most detectors have five or six indicator symbols for typical finds, like coins.

Operating Frequency

The operating frequency of a metal detector is the number of times per second that the signal is transmitted and received by the detector. Low-frequency metal detectors are able to scan deeper into the ground, which is why they’re very good for finding large, buried objects. In general, most metal detectors have a low- to medium-frequency range.

If you seek gold or small objects, you might want a device that operates at a higher frequency. While these high-frequency metal detectors have less penetration depth than a low-frequency detector, the high frequency of the transmissions allows these detectors to identify small objects that would elude a low-frequency detector.


The sensitivity of a metal detector refers to how well it can detect conductive materials from a specific distance. Most metal detectors are labeled with the recommended sensitivity level that is appropriate in most applications. In some situations, the user may have to lower the device’s sensitivity level for it to work effectively. The level might have to be adjusted, for example, if the search area is high in mineral content or is near power lines.

On the other hand, you may have to turn up the sensitivity level if you find that the device is not reacting properly to the presence of conductive materials. Just be aware that if you set the detector’s sensitivity too high for the application, then you’ll likely receive a lot of distortion and static instead of clear indicator sounds. Lowering the sensitivity should rectify the issue.

Search Depth

The depth that a metal detector is able to search for conductive material is known as its search depth. Typical search depths vary greatly between products: They range from about 2 inches to 15 inches. Lower-frequency detectors offer a better max-depth rating than high-frequency detectors.

Keep in mind that search depth isn’t just dictated by the metal detector you use. Your location, the type of ground you’re working with, and interference above or below ground can all reduce or improve your metal detector’s search depth.


A metal detector’s weight is a factor that is often overlooked, but shouldn’t be. You’ll be lugging a metal detector for long periods of time. Choose one that you won’t have to struggle with so that you can focus on the readings and your findings.

If you’re buying a metal detector that you’ll share with others, think carefully about who you’re sharing it with. Children will need a metal detector that isn’t too heavy, and preferably one that can be adjusted to an appropriate height. Sharing a metal detector with another adult who’s different in size or strength will also impact which detector you select. Those with back or shoulder injuries should avoid heavy detectors that could exacerbate existing health problems.

Before investing in a new metal detector, take a look at these frequently asked questions and their answers below.

Q: What makes a good metal detector?

A quality metal detector should have features that will help the user get the most accurate readings possible. These features include a ground balance setting to focus the detector on specific materials, and high-quality sensitivity control. Look for a model with fast reactivity time, so you can pinpoint or pick up several objects in a single sweep.

Q: How deep do most metal detectors go?

Most metal detectors can detect materials at depths between 2 inches to about 15 inches.

Q: Which metals do metal detectors detect?

Most metal detectors should be able to detect various types of metal, though the type of detector will impact how strong the signal is from less conductive metals like aluminum, iron, zinc, lead, or heavily corroded or coated metal objects. These kinds of metals have less of an electromagnetic signature for the detector’s magnetic field to pick up.

Q: Can a normal metal detector find gold?

All metal detectors can find gold if it’s within the device’s prescribed depth range and the pieces of gold are big enough for the detector to find. A gold metal detector is a specialized device designed specifically for finding gold.
