The Fisher F70 is a high-performance metal detector built for enthusiasts who demand precision in a wide range of detecting environments. Ideal for coin shooting, relic hunting, and even shallow water searching, the F70 combines professional-grade performance with user-friendly controls. Its standout feature is the intuitive GroundGrab™ ground balancing system, which helps maintain accuracy even in mineralized soils.

Operating at 13 kHz, the F70 delivers excellent sensitivity to small and deep targets, including gold, jewelry, and coins. It features both Discrimination and Autotune search modes, a pinpointing function with depth indication, and a large LCD screen showing target ID, confidence, and mineralization levels. Users can fine-tune performance with adjustable sensitivity, threshold, and notch settings, while the multi-tone audio helps distinguish metal types. With programmable memory slots, it adapts easily to varied detecting conditions.

Weighing just under 3 lbs and equipped with an adjustable armrest, padded grip, and waterproof 9.75” elliptical searchcoil, the F70 is built for long hunts without fatigue. Its locking collar design reduces rattling during use, and the intuitive interface makes setup and operation effortless.
