The OPENGATE system is a battery-operated walk-through detector that consists of two free-standing pillars that are 6 feet tall. Metal-detecting hand wands were also purchased and can be used in ...
Magnetometers can be used as metal detectors: they can detect only magnetic metals, but can detect such metals at a much greater distance than conventional metal detectors, which rely on conductivity. Magnetometers are capable of detecting large objects, such as cars, at over 10 metres (33 ft), while a conventional metal detector's range is ...
