The 11-inch FMF coil is waterproof to 20 meters (65 feet) and supports full submersion for saltwater surf hunting and river wading. The wireless design eliminates cable connections that can corrode in saltwater, and the coil-housed battery removes the need for a control-box harness in chest-deep water. The multi-frequency transmission adapts to shifting mineralization levels in wet sand and surf zones without manual rebalancing, and you can lock to a single frequency like 15 kHz for small gold chains in dry sand or run a multi-frequency program when working the wet-sand transition zone.
