Description:
The metal detector is a portable electronic instrument which detects the presence of metal nearby.
Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground.
They often consist of a hand-held unit with a sensor probe which can be swept over the ground or other objects.
If the sensor comes near a piece of metal this is indicated by a changing tone in earphones, or a needle moving on an indicator.
Usually the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes.
