The Metal Detector MachineMetal detectors use electricity to generate electromagnetic waves that they project into the ground. A buried metal object will respond to these electromagnetic waves by creating its own electromagnetic response that the detector interprets as a sound or numerical value that indicates target type; these signals are transla

How to Use a Metal DetectorMetal detectors are tools designed to locate pieces of metal, coins or jewelry. It works by producing an alternating magnetic field using an oscillator; when an electrically conducting material such as iron comes within range of this coil it causes its magnetic field to change, which is then detected by another coil locat

Raw Gold DetectorsRaw gold detectors are metal detectors designed specifically to locate raw gold nuggets and other treasures underground. They work by transmitting electromagnetic waves which, when bounced off an object such as a gold ring or coin, hit their receiving coil and transmit a signal back.When purchasing a gold detector, look for one wi
