Metal Detector Search Coils

A coil swap changes a detector more than most people expect. A small DD or elliptical will separate targets in trashy parks and iron-infested relic sites where the stock coil smears everything together. A 15-inch DD buys you depth and ground coverage on open fields and beaches, at the cost of weight and target separation. Mono coils belong on pulse machines in the goldfields. Whatever you are running, check the coil is built for your exact model and firmware before you order, because connectors and tuning are not interchangeable between brands. We stock factory coils alongside aftermarket options from Coiltek, CORS, Mars, NEL and Detech.
