The F75 is a multi-purpose high-performance computerized metal detector. It has the high sensitivity and ground balancing control needed for professional gold prospecting, the discrimination responsiveness needed for serious relic hunting under difficult conditions, and the visual target ID considered essential in searching for coins. The F75 operates at 13 kHz for good sensitivity to gold nuggets and jewelry as well as to coins. The F75 comes with an 11-inch elliptical Bi-Axial search coil for maximum detection depth in mineralized soils.

The F75 is among the lightest and best balanced of all high-performance metal detectors, so you can hold and swing it almost effortlessly. The armrest position is adjustable to fit your arm. The grip is durable high-friction foam elastomer, comfortable in any kind of weather. The controls are conveniently located and easy to learn how to use. Locking collars on the tubes eliminate rattling.

The entire menu is always visible on the LCD display. The LCD display indicates the electrical signature (target I.D.) of the detected metal object. The display provides continuous information on battery condition and on-ground mineralization, which affects detection depth. Help messages are automatically displayed on the bottom of the display when necessary.

The F75 is powered by four AA alkaline batteries, which will typically last for more than 40 hours of use before needing replacement.

The lead engineers on the F75 design team were John Gardiner and David Johnson. David Johnson’s previous Fisher design credits include the CZ-platform, the Gold Bugseries, most of the 1200-series, Impulse Underwater Detector, CZ-20 Underwater Detector, FX3 magnetometer, the Gemini 2-box locator, the XLT-16 Acoustical Leak Detector, and the XLG-80 Ultrasonic Leak Detector. John and David were supported by fellow electrical engineers Jorge Corral, and Mark Krieger. The mechanical design was a collaboration among David Johnson, Brad Fulghum, John Griffin, and Tom Walsh.
