The AT Gold metal detector was designed to find tiny gold nuggets in the most challenging prospecting environments, including shallow fresh water hunting. The AT Gold operates at a high frequency optimized for gold prospecting and includes a True All Metal Mode. The All Metal Mode is preferred for prospecting because it provides the greatest possible depth and sensitivity. It also provides a continuous audio response to allow the operator to hear the subtle detection signals produced by faint targets. The AT Gold is a Motion All Metal detector, meaning that slight motion of the search coil is required to maintain detection, although static detection of targets can be achieved while in Pinpoint mode.
