How do metal detectors work?
To achieve the best performance from your metal detector, it is important to understand exactly how it works and why it 'beeps' when it comes across a metal target.
A metal detector consists of three basic parts: (a) the coil (b) a power supply and (c) the control box.
Inside the coil there are normally two sets of copper wire windings. As electrical current from the detector is passed through one of these windings, an electromagnetic field is created and sent into the ground. This is commonly called the transmit winding.
Metal objects conduct electricity and will therefore alter this electromagnetic field. Alteration to the field caused by the presence of a metal object is picked up by the second winding in the coil, known as the receive winding. This alteration is sent to the control box where it is interpreted as a metal object and an audible signal is given to alert the operator.
