WHAT IS A METAL DETECTOR COIL?
A metal detector coil, also called a search coil, is a coil of wire at the end of your metal detector. This is the part of the metal detector that you sweep along the ground to discover metals hidden beneath the surface. The coil is probably the most essential part of your metal detector, as it detects metals and treasures underground.
How Does a Search Coil Work?
A search coil works by transmitting an electric current, which creates a magnetic field between itself and the ground. When the magnetic field bounces back towards the metal detector, the search coil receives the information and analyzes it. The electrical impulse will change if it comes in contact with metal, which then alerts the search coil that metal is present. If metal is found, the search coil will send an alert through the control center, which lets you know it’s time to dig!
