Metal detectors are useful for finding metal inclusions hidden in objects or metal objects buried underground. They often consist of a handheld unit with a sensor probe that can be swept over the ground or other objects. If the sensor approaches a piece of metal, this is indicated by a change in the sound in the headphones or by a needle moving on a pointer. The device usually provides some indication of the distance; the closer the metal is, the higher the tone in the headphones or the higher the needle moves. Another common type are stationary metal detectors, used for security screening at access points in prisons, courthouses, and airports, to detect metal weapons concealed on a person's body. The simplest form of a metal detector consists of an oscillator that produces an alternating current that passes through a coil.. metal detector, metal detection, gold detector, metal detection 2021, metal detection romania, gold seekers, metal detector romania, detector, metals, metal detectors, metal detector romania, ro detecting, are you allowed with a metal detector, I found gold with the detector, am I allowed with a metal detector in germany, metal detector, silver detector, archaeologists and metal detection, alluvial gold, gold found with the metal detector, detector authorization You can subscribe here: / @mihaistanciu2701 Facebook: / detectieprahova Instagram: / mihai1977
