When to use the 10COIL-F70
Fisher's F70 manual says the open-frame concentric elliptical coil is made for a broad sweep. A concentric coil pinpoints easily, while the F75's standard 11 inch Bi-Axial coil is the one Fisher points to for maximum depth in mineralized soils. Fisher says its searchcoils are waterproof for shallow water about 2 ft (0.6 m) deep.
On ground with little mineralization, the 10COIL-F70 gives F70 and F75 owners an easy-handling concentric option with a wide sweep. Overlap each pass, and fit a smaller coil where junk lies thick. In hot soil, Fisher's DD coils are the better choice. Our metal detector coil guide explains how coil size and type trade coverage for separation.
