The Fisher F75 Limited Edition Metal Detector is a multi-purpose high-performance computerized metal detector.
The F75 Limited Edition comes with a more powerful microprocessor and new DSP code implementing two new signal algorithms – The “Boost Process” substantially increases depth under most conditions, and the “Cache Locating Process” is designed to find the large deep objects.
The F75 Limited Edition operates at 13 kHz for good sensitivity to gold nuggets and jewelry as well as to coins. The F75 Limited Edition comes with an 11-inch elliptical Bi-Axial search coil for maximum detection depth in mineralized soils and a 5″ DD coil for trashy areas.
