A metal detector is a device that uses an electromagnetic field to detect metal objects, such as concealed weapons, by distorting the normal electromagnetic field when eddy currents are generated on the metal detector.

Hand held metal detectors are designed for quick and efficient body search scanning for knives, weapons and concealed metal objects. Metal detector wands offer a practical, low cost alternative to airport style walk through, arch type detectors which are designed for rapid scanning of high volumes of people.more used in mall airports etc.
