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.

Geocaching with a Metal Detector

Metal Detecting and Geocaching – Enjoy Both Hobbies Together for Twice the Fun

Metal Detecting and Geocaching are two really fun and exciting hobbies. But, they’re pretty different. Or are they? Well, in some respects metal detecting and geocaching are different. When you head out with your GPS coordinates to find your geocache, you’re not expecting to dig or wander around until you find your treasure like you would if you were going metal detecting for a treasure cache. That said, these two hobbies actually have more similarities than they do differences.

Just to name a few, both Metal Detecting and Geocaching are:

  •     Excellent forms of exercise
  •     Great ways to enjoy the thrill of hunting for treasure
  •     Hobbies that get you outside in nature
  •     Activities that take you to new and wonderful places
  •     Things you can enjoy alone or with family or friends

Actually, even if we only look at this short list of things metal detecting and geocaching share, it’s easy to see that these two unique hobbies could actually benefit each other and

be enjoyed together for even more treasure hunting fun. For example, geocaching can give metal detector enthusiasts a starting point to begin looking for buried treasure as well as a guaranteed find; something that doesn’t always come with metal detecting.

When geocaching in and around cellar holes and old home sites, bring your metal detector along. These are great spots to find treasure as well. In fact with a metal detector you can easily pinpoint targets through the various layers of debris, walls and other obstacles. Simply put, after you have found your geocache, your metal detector will help you find coins and relics commonly found around old home sites.

As you can see, geocaching and metal detecting really do go hand in hand. The only question left is, what’s the best metal detector for geocaching?

This is a question that doesn’t have just one answer and instead, it will actually have a different answer for each person. The type of metal detector that’s best for anything,

including geocaching, varies from person to person. Some factors to consider when deciding on which metal detector will be right for your geocaching expeditions include whether or not you’ll be near water, your height and strength, and, as always, your budget.

With these personal preferences in mind, some of the best entry level metal detectors for geocaching are made by Bounty Hunter Metal Detectors. The Bounty Hunter Platinum is a great starter model. Garrett Metal Detectors also makes a great model for geocaching, the Garrett AT Pro. If you’ll be near water for even part of the time this is a great choice. If you just want the best, the top of the line model is the XP DEUS. While they each have different features and strengths, any one of these metal detectors will help you find that buried treasure cache more easily. Use the links to each of these models, above, for full details on each one and to read metal detector reviews left by experienced users.

And, whichever model of detector you choose, you’ll definitely enjoy geocaching and metal detecting even more when you combine them together for one exciting trip. Each hobby has so much in common, that, when they’re done together, it makes both more fun than ever before!
