Hand-held metal detector is a kind of metal detector, which is named because it is operated by hand. Mainly used for anti-theft in factories, places and examination rooms. Compared with security doors, hand-held metal detectors are more accurate. Alarm is through the electromagnetic induction of metal objects, mainly through sound and light, vibration, or through headphones.

Hand-held metal detectors are used to check the specific position where people carry metal, and can also be used in conjunction with metal detection doors. When the "security door" alarms to find a metal object, you can use the hand-held metal detector to find the exact location where the metal object is hidden. The metal detector adopts a rectangular probe with a detection area of 12 cm. When examining the human body, the examination work is completed at one time from top to bottom.
