When to use the 11COIL-F75
Fisher's F75 manual says the 11 inch elliptical Bi-Axial coil is there for maximum detection depth in mineralized soils. The same manual notes that Double-D coils have a reputation for difficulty telling steel bottle caps from coins. Fisher says its searchcoils are waterproof for shallow water about 2 ft (0.6 m) deep, and the coil is electrostatically shielded.
For F75 and F70 owners the 11COIL-F75 is the general-purpose coil, the one to leave on for coins and relics across open and moderately littered ground. Around concentrated iron, slow down and work each signal from more than one direction, or change to one of Fisher's smaller coils. Redo the ground balance whenever you change coils. Our metal detector coil guide explains how coil size and type trade coverage for separation.
