Gold detection metal detector without sensor

A circuit that is designed according to the principles of a detector or metal detector or  ground handy radar and mine detector can in practice detect and identify metals, especially gold, in depth, according to the type of circuit design, by emitting magnetic current or field frequency, and the presence of sensors is the main factor. It is an aid in the circuits of the detectors, and all types of sensors and accessories are auxiliary factors and they do not perform the main task of detecting the field of metals and gold, but the circuit detector or metal detector or ground handy radar or mine detector perform the main task to detect metals and gold. Data and sensors and accessories increase the ability and accuracy. As a result, a detector or metal detector or manual ground radar or ground handy radar or mine detector will have the detection conditions according to the principles of its circuit, and a detector or metal detector or manual ground radar or real mine detector without sensors. devices or accessories can reveal the field of metals and gold, and the scientific and practical principles of revealing the field of metals and gold can also be recognized and separated without sensors and accessories.
