A metal detector is an instrument which detects the presence of metal in ground or in any other place . Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects.
it's structure :
A typical metal detector is light-weight and consists of just a few parts:
Stabilizer (optional) - used to keep the unit steady as you sweep it back and forth
Control box - contains the circuitry, controls, speaker, batteries and the microprocessor
Shaft - connects the control box and the coil; often adjustable so you can set it at a comfortable level for your height
Search coil - the part that actually senses the metal; also known as the "search head," "loop" or "antenna"
