Fully waterproof, these Mono and Double-D 12x8" Goldhunting Elliptical Search coils are the only coil for prospecting the shoreline, rivers and wet terrains.
These coils are potted with epoxy resin, holding all windings secure. These coils are tough enough to withstand the knocks and bumps of a normal swing action. Choose the DD coil for more stability in highly mineralized soil types. The DD coil offers good depth and sensitivity too. Choose the Mono coil for excellent depth and target separation. Mono coils have slightly more depth but require more overlapping sweeps of the Coil.
