Introduction to the Fisher F70
HIGH PERFORMANCE
detector. It has the high sensitivity and ground balancing control needed for even the
most challenging soil conditions, the discrimination responsiveness needed for serious
relic hunting under difficult conditions, and visual target ID considered essential in
searching for coins. The F70 operates at 13 kHz for good sensitivity to gold nuggets and
jewelry as well as to coins. The F70 comes with a 9 3/4"-inch open-frame waterproof
concentric elliptical search coil for broad sweep yet narrow target pinpointing.
USER COMFORT The F70 is among the lightest and best balanced of all high-performance
metal detectors, so you can hold and swing it almost effortlessly. 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.
