The HS90V Hand Held Metal Detector is ideal for use in airports, border checkpoints, conferences, government buildings, hospitals, industrial sites, prisons, schools, seaports, sporting events or anywhere where security is required. It is sensitive enough to detect metal objects the size of a 25-cent coin from 60mm.
It will sound a high-pitched tone or vibrates when it detects metal, a longer tone for larger objects, and a shorter one for smaller objects.
It operates from a standard 9v DC battery. Optionally a rechargeable battery can be used.
