How the Shape of Your Metal Detector’s Search Coil Effects Your Treasure Hunting Success

Search Coils

Owning the right type of search coil that matches your metal detector will make it easier when searching for treasure.

The shape of the search coil you use on any of your metal detectors will change the capabilities of your machine and, as a result, having several different types on hand will really enhance your treasure hunting experience. In fact, many metal detectorists feel that you can transform your metal detector into an entirely new machine simply by selecting different size and shape search coils as opposed to actually buying a whole new machine! There are two parts of a search coil to talk about when discussing their shapes. First is the shape of the search coil itself. The search coil itself will be either round or elliptical – most will be round. More important than this though is the internal construction. The way the wires are attached to the coil internally will take one of the three following forms – Concentric, Double D, or Coaxial – each giving your metal detector different capabilities. Let’s discuss each of these search coil designs, their benefits, drawbacks, and more.


Concentric circle search coils are probably the most popular design of search coil for metal detectors today. Most commonly used for finding smaller targets like gold, jewelry, coins, and relics that are generally found near the surface concentric coils are also excellent at target discrimination and pinpointing. They’re drawback? Concentric coils are easily compromised in heavily mineralized soils.

Double D

A Double D search coil is designed in the shape of two capitol letter “Ds” hence it’s name! Double D metal detecting search coils are reliable in heavily mineralized soils, like what you run into at the beach for example, and cover more ground in one sweep than other types of coils. They’re not as good at pinpointing nor as adept at target discrimination; although many of the newer DD coils being made today are.


Coaxial coils are probably the least popular search coil design type and are rarely found on metal detectors made today. While it’s detection depth is usually lower, the coaxial search coils are the best type of coil to use when you need to minimize interference from utility wires or other metal detectors. Coaxical coils are also great at pinpointing and discrimination even in areas with very heavy trash.

All shapes are generally available in all sizes (extra small/mini, small, medium, and large) and vice versa. Whatever size and shape search coil you buy for your metal detector though, be sure you’re purchasing quality search coils that are compatible with your metal detector in order to avoid violating any warranties or, worse, causing your machine to malfunction. You’ll also need to consider the type of metal detector you’re using, the frequency it operates on, and, as we mentioned, where you’re working, and what you’re hunting for. From there though you’ll easily be able to buy all the right shapes and sizes of search coils to find treasure wherever you’re metal detecting.

What Does a Metal Detector’s Search Coil Do?

search coil

The search coil of your metal detector allows you to better scan the ground for hidden treasures.

The finest metal detector in the world is no better than its search coil, so be sure not to overlook your search coil’s importance in treasure hunting. The type of search coil you use will determine how effectively your metal detector will perform the task at hand. What exactly is the search coil’s function? The search coil is mounted on the lower end of the detector’s stem. It takes power from the control housing through the search coil cable. Then, it transmits data between the metal detector and the ground. The search coil simply scans to allow the metal detector to find metal targets.

Most search coils operate with electromagnetic transmitter and receiver antennas embedded within the search coil. An invisible electromagnetic field is generated and picks up signals from the surface you’re scanning—soil, rock, water, sand, etc. Search coils designed by major manufacturers and provided with their detectors are generally reliable because they are maximized for performance. However, experts say there is no such thing as a standard search coil. A coil that operates perfectly in the park may not be suited for a pop-top filled beach. Search coils that find coins are not the same as those used to search for a treasure cache. There is also the issue of moisture and/or water-resistant capabilities. Find out if your search coil can resist a small amount of moisture, is waterproof for operating in heavy rainfall, or is fully submersible. Most coils made today fall into this last category of fully submersible.

Size Matters When it comes to Search Coils

Search coils come in many shapes and sizes. In general, the smaller the search coil, the smaller the object that can be detected. Larger search coils are designed to detect larger, deeper targets—but they can often locate small objects at deep depths, too. From small to large, search coils are designed with specific objectives in mind. Here is a snapshot of sizes & functions.

3-5″ Diameter: Very small search coils, also called “Snipers,” are ideal for trash-filled areas, allowing a detectorist to pinpoint coins in spite of nails and other junk. These search coils are able to maneuver in tight spots and around obstacles. They will signal at the detection of small and shallow targets. However, depth of detection is not as great as larger search coils.

7-9.5″ Diameter: This size search coil is what comes equipped with most detectors. 7-9″ search coils are usually the best for coin hunting and general purpose treasure hunting. These search coils are lightweight with a good scanning width and they are sensitive to a wide range of targets. Mid-range search coils offer decent depth of detection.

10-12″ Diameter and Larger: Large search coils are designed to detect coins and other targets at greater depths. Precise pinpointing is more difficult with the larger sizes because they pick up more mineralization. But these search coils are beneficial for finding, large relics and treasure caches. They provide considerable ground coverage, so you can cover a lot of ground more quickly than with a medium search coil.

Digging and Retrieval of Coins with Metal Detectors

Digging and Retrieval of Coins

Michael Bernzweig of is above metal detecting with the the Lesche digging trowel says "When trying to find buried coins, having the right tools will make it easier to find and retrieve them."

Once your metal detector has given you a strong signal and you’ve located a coin or something more valuable, how do you dig it up without damaging your find? Expert coin hunters give much advice on the safe retrieval of coins and interestingly, it’s all different. They say it depends on the kind of turf you’re digging. Each type of soil can require a different digging and retrieval method. Recovering coins from the beach may be easy, but digging coins from hard-packed clay is much more difficult.

Michael Bernzweig of said “Garrett Metal Detectors are one of the most popular brands for locating coins and valuables.” He went on to say “If you are looking for our top metal detectors for sale be sure to check out our top 10 list.”

For recovering coins on the beach, many people use two tools—a wire mesh or stainless steel sand scoop sifter and a small trowel. When they have pinpointed a metallic object with their detector, they scoop through the sand with a sifter. If the sand is loose and fine, the object may be in the sifter. However, if the coin is in wet sand near the water, it’s time for the trowel. After pinpointing, a detectorist will insert his/her trowel several inches into the beach sand and with one quick twist, remove the clump of sand. Hopefully, the coin will be at hand. Otherwise, keep digging with the trowel. It’s important to use tools for beach retrieval because you may encounter broken glass.

Other Methods for Probing and Retrieval

Some coin hunting experts like to use knives when retrieving their finds. They cut a plug of grass about three inches deep. When folding the turf back, the coin is usually in the plug of dirt. If not, you can remove a second and deeper plug. You can use a pinpointing metal detector to locate the target within the hole. After retrieving the valuable, you can fold the turf back into place and secure it. A stainless steel digging trowel is a great way to retrieve your target. Treasure digging trowels have marks to gauge the depth of a hole and they help to avoid marring coins while digging. You can shop for Digging Tools, Pinpointing Probes and Metal Detector Accessories at

When you click on the Browse Shop tab in the top navigation, you’ll see the Shop Accessories category. There are subheads for each accessory category, making it easy for you to locate what you’re shopping for. You can even find digging kits, such as the Garrett Treasure Digger Kit, which comes with a pouch, probe and trowel. Shop by Features or even do side-by-side comparisons by adding two products to review.

Types of Retrieval Equipment for Metal Detecting

Among the useful tools that you will need for locating and recovering coins are a knife such as the Lesche Digging Tool, stainless steel trowels, pinpointer and some type of apron or pouch. Electronic Pinpointer metal detectors are considered a gem among retrieval tools for many coin hunters. Electronic pinpointers help speed up recovery while adding extreme accuracy. The most popular model on the market today is the Garrett Pro-Pointer. Knives are essential for cutting plugs; metal detecting knives allow you to be exact, precise and quick. Trowels specifically designed for this hobby are typically made of hardened stainless steel. They come in many sizes to adapt to your needs.

Diggers: A New Metal Detecting Show on National Geographic You Should Be Watching shares information on National Geographics Diggers television Show

National Geographic's new show Diggers is a must watch for those who love metal detecting as it provides an inside look into how the pros do it.

Today we’re excited to share a fun new show with you that we’ve all been enjoying on the National Geographic Channel called Diggers. The show is about two guys based in Montana, Tim Saylor and George Wyant (AKA Ringy and The King), who love metal detecting. They head out into all kinds of different terrain all around the country and film their adventures. They’re fun to watch because you can tell that they truly enjoy the hobby. They’re both knowledgeable about metal detecting as well as history so they are able to create a solid mix of entertaining and informative content too. Plus, when one of them actually finds something; let’s just say they’re not low key about it!

Some hobbyists and pro metal detectorists comment that Nat Geo’s Diggers is overly dramatic and the actors use slang that is not representative of the hobby. Nonetheless, we find it to be entertaining as it unveils the hobby of metal detecting to the public. Perhaps it will inspire newbies to test their hand at this amazing hobby.

Metal Detectors Used on Diggers TV Show

Watching Diggers is also neat because we get to see all kinds of cool, high tech metal detectors and detecting equipment in action. You can watch them search with their Garrett AT Series metal detectors and even hear the signals as they would through their headphones. There are two Garrett detectors in the AT Series. The Garrett AT Pro used more for coins, relics and jewelry and the Garrett AT Gold for gold nuggets. Watch as they pinpoint their targets with the Garrett Pro Pointer, and dig everything up with their Lesche Digging Tools. These are some of the best metal detectors out there, products we’ve sold for a long time, and, unless you were using them yourself, seeing them out in the field like this used to be rare. Ringy and The King are changing all that though with Diggers the television show.

Diggers not only provides metal detectorists with the honor of finally having a show that celebrates our hobby though, it’s also turned a lot of folks onto the spectacular world of metal detecting that didn’t know about it before. Tim Saylor and George Wyant explain the basics as they go through a show, yet, they have a way of talking about what they’re doing that doesn’t distract from the fun of the program for more experienced metal detectorists either.

And then there’s the sites they get to explore. Whether you’re a metal detector yourself or not you can’t help but think it’s cool when they verify a former Buffalo Soldier camp by finding soldier’s buttons and coins from that time, or when they get to search the site of an old hotel locating jewelry, antique bottles, rare coins, and more.

They don’t always keep the treasures they find from sites like these. When they searched the hotel site for example, they were assisting the property owners and a local historian who were starting a museum about the famous property and were given access to the site on the condition everything they found went to the museum. But, Ringy and The King didn’t get into metal detecting for the money (they say they actually end up spending money each time they go out!). They’re in it for the thrill of the hunt. So, they say, whether they come away with a treasure jackpot or not they’re always having a good time because they’re out metal detecting.

In addition to Tim Saylor and George Wyant Diggers also employs an Archaeologist, Kate Culpepper, to authenticate the finds and add additional historical information to the show. She ensures all the metal detecting is done in an ethical way and that it respects the historical integrity of each site they visit as well as the artifacts the guys find. If you are new to metal detecting, we ask that you read the “Metal Detecting and Treasure Hunter’s Code of Ethics“.

So, if you’re a metal detectorist, have one in your life, or are just looking for some good TV, you won’t want to miss Diggers on the National Geographic Channel and at It’s authentic metal detecting with awesome equipment on a show that’s just simply fun to watch!

Accessory Necessity: Metal Detecting Headphones

Metal Detector Headphones

Owning the right metal detector headphones can help make it easier to find hidden treasures.

Do I really need to buy separate headphones for metal detecting? This is a question that Michael Bernzweig of gets asked a lot. His response, “You should always wear headphones when you search with a metal detector. In noisy areas, such as the beach or near traffic, it’s the only way to filter out interference and hear your signal.” As a rule, you will hear weaker sounds and detect deeper targets when quality headphones are used.

Quality headphones for metal detecting don’t cost a fortune, either. You can find a good set for under $50. See our metal detecting headphones page to view our full product selection, compare features and prices. The Depthmaster Audiophone II is our most popular model as it offers top quality features at an affordable price. Another reason headphones are invaluable is that most detectors are operated at full volume with the audio control adjusted so that a faint sound continually comes from the speaker. When a target is detected, the volume increases to maximum loudness. Headphones allow you to set the threshold lower, thus hearing more, more deeply and thereby increasing your finds. To answer whether you need headphones other than the ones you already own, read: Choosing a Metal Detector Headphone.
