Fisher Gemini 3
Management is carried out by several regulators, the location of the frame (transmitter and receiver) relative to each other depends on each other depends on the chosen type (mode) of the search, the options are detailed in the instructions.
Views (search modes):
Search with a little scan coverage. This mode of operation is carried out by a single operator using a three-section bar. This is the best way to detect short and small items (chests, cans, shotguns). However, it is also effective for detecting pipes, cables and ore veins.
Search with extensive scan coverage. This mode is preferable for a quick search (intelligence) in large areas. This requires two operators, the barbell is not used. A wide-scanning mode is recommended when searching for ore veins, pipes, or cables more than 40 feet long.
Tracking. Usually used to trace long objects that do not reach the surface of the earth, but are known starting points (pipes, wires or other objects).
