Turn your Pulse 6X or 8X into a boat deployed metal detector with this coil and cable assembly. It boasts a very large detection area which extends up to five feet on either side of the coil and seven feet below it. It is great for locating outboard motors, anchors, moorings, cannons, etc. The 18" coil can be mounted on a sled and towed across the bottom. The JW Fishers underwater connector is needed to use this coil.
