MD-300 Hand Held security Metal Detector

The MD-300 is a hand held metal detector that can detect metal objects hidden in clothing and other items. The device uses a physical search method to locate the target item, which means it will scan an area around the person being searched and indicate whether or not there are any concealed items.

The MD-300 has two modes of operation: manual and automatic. In manual mode, the operator places the device on the surface of an object that is being searched for metal objects and then presses the button on the top of the device to start scanning. When an object is detected, an audio signal will sound and a green light will flash to indicate that there is something present. In automatic mode, once activated by pressing a button on top, the device begins scanning continuously until it detects something or its power runs out.
