One of the most important parts of a metal detector is it’s search coil. Search coils help determine in part how deeply the metal detector can search, the size of treasure it can find, the way the machine reacts to the type of ground you’re hunting, and more. Let’s take a minute to talk about the types of search coils available and how to determine which metal detector search coil that would be best for you.

Search Coil Size: Small, Medium or Large?

Search coils come in small, medium, and large sizes. Smaller metal detector search coils will find smaller treasures closer to the surface, like gold flakes for example. Larger sized search coils are used for finding larger items like treasure caches of coins that are buried deeper underground. Mid sized search coils fall in about, you guessed it, the middle with regard to the size and depth of treasure they can locate.

The type of metal detector search coil has an effect on your treasure hunting as well. The two most widely used search coils found on metal detectors at this point in time are:

  1. Concentric
  2. Wide Scan

Concentric metal detector search coils offer improved target discrimination while you should choose a wide scan search coil if you’re hunting in a location with heavy ground mineralization like the wet salt water beach.

One company to look to when selecting an additional search coil is Detech. Detech makes search coils for a wide variety of metal detector models from today’s top brands.
