White’s GMT Metal Detector

White’s GMT Metal Detector

White’s GMT Metal Detector canceling detectors are capable of finding gold nuggets in the ground.
However, none will perform as efficiently as the line of Goldmasters created especially for nugget
hunting. The new GMT is the culmination of a series of Goldmasters, refined and improved over
the years. With the addition of Fast Ground Tracking the GMT is the ultimate Goldmaster.
The reason the Goldmaster stands above all other detectors in finding gold nuggets is the
care taken to accommodate the particular conditions encountered while gold prospecting. Since
gold is most often found in highly mineralized soil, it was necessary to design a ground balance
circuit which had the range to cancel out both extremes (+) and (-) mineralization. The GMT has
made it easier to achieve and monitor ground rejection by utilizing digital microprocessor software to automatically track out (eliminate) ground mineralization. In addition to automatic elimination of ground minerals, the GMT retains the manual ground balancing system perfected for its
predecessor, the GM/4B. In this way, the GMT will satisfy both preferences, manual or automatic.Technical Specifications:
