Tesoro 9x8 Inch Concentric Spoked Searchcoil

The 9 x 8 Inch Concentric Spoked Searchcoil is perfect for coin jewelry and relic hunting. The concentric coil uses two round antennas one inside the other. This coil is used on most detectors that are designed for coin jewelry and relic hunting. Concentric coils discriminate very well and pinpoint very easily because the strongest signal is always in the center of the coil.
