Metal Detector

Metal detector. This category includes metal detectors of traditional design - devices designed to search for metal objects in the ground or under water in vast spaces. Such devices in most cases have a characteristic design - with a long rod, at one end of which there is a handle, at the other — a coil. The accuracy of metal detectors in most cases is quite low – about 20-30 cm, they make it relatively easy to find the right objects over a large area, however, to determine the exact location, most likely, you will have to dig the ground manually or use a pinpoint.
