Metal detectors are used in many industries for the detection of metal objects. The utilization of metal detectors to search out and find metal objects is a well developed art that has become increasingly important in recent years. Metal detectors have been used to screen foodstuffs for the presence of foreign ferromagnetic or electrically conductive objects. Metal detectors in the food industry typically radiate an electomagnetic signal having a single operating frequency in the range of fifty kilohertz to two megahertz. Metal detectors are popularly used by hobbyists and collectors to search for buried or otherwise hidden metal objects of value or particular interest, such as coins, jewelry, and artifacts of historical significance. Metal detector systems are utilized in airports and security buildings to detect transport of weapons by individuals. Metal detectors are also used in other industries such as plastics, timber, and quarrying for the protection of machinery. Metal detectors work by generating a low intensity magnetic field from a current flowing through a coil of wire and examining the various types of distortions produced in this field by a surrounding matrix of materials. The sensing coil and sensing circuit are used to detect presence of a metal object in the zone by comparing perturbations in the magnetic field caused by the presence of the metal object to a threshold value. Some metal detectors identify target type by analyzing the phase relationship between a signal transmitted into the ground and a received signal.
