6" Concentric 7.5 kHz Coil

 If there are coins and relics hiding amongst iron junk, this coil is the one that will find them. The best X-TERRA coil for target separation. Water proof: Submersible to 1 meter. Ideal for shallow water wading and gold prospecting in shallow streams.

A Concentric coil has an inner circle and an outer circle wire winding. Its search pattern is cone shaped and can be useful for accurately pinpointing the target. Concentric coils tend to be noisier in highly mineralised ground and require more overlap of sweep for thorough ground coverage.

All X-TERRA series detectors
