Operating a metal detector is simple. Once you turn the unit on, you move slowly over the area you wish to search. In most cases, you sweep the coil back and forth over the ground or person in front of you. When you pass it over a target object, an audible signal occurs. More advanced metal detectors provide displays that pinpoint the type of metal it has detected and how deep the target object is located.

Metal detectors use one of three technologies, very low frequency, and beat-frequency oscillation.
