Fisher metal detectors Founded in 1931, under the experimental conditions very difficult circumstances, developed the world's first metal detector. After nearly a century of painstaking research, has become the best-known brands in the field detector. Fisher metal detectors use the most cutting-edge technology, it has become one of the most trusted brands. Fisher metal detector treasure-hunting was a favorite among fans, because of its versatility, depth and wider use of the most cutting-edge technology, and is very easy to use and technical innovation. New gold exploration experts in all gold detector is outstanding. It also has a small nugget high resolving power control and function is designed specifically for the detection of gold, including sophisticated ground balance system, numerical signal obtained and threshold separation design, unique to distinguish control mode.
