J.W. Fisher's 8"x48" Oval Coil with Skids and 100' of cable (deploy from boat)
The 8" x 48" (203 mm X 1219 mm) coil has the largest detection area of all the optional coils. For a large target, such as several cannons or a ship's boiler, the detection envelope extends 4' (1.3 meters) to either side of the coil 12' (3.66 meters) total width and 8' (2.44 meters) below the coil. The coil is mounted on four small skis for dragging along the beach or in shallow water. This coil is ideally suited for locating buried targets because it travels just inches away from the bottom.
The unique oval design gives this coil both good sensitivity to small targets (rings, coins, etc.) and deep detection of larger targets. The coil has been used by treasure hunters worldwide for locating coins and jewelry along beaches as well as gold and silver bars at wreck sites. The P6/8X must be ordered with the optional u/w connector to use this coil.
