The HS90V Handheld Metal Detector is ideal for use at border checkpoints, conferences, government buildings,hospitals, industrial sites, prisons, schools, seaports, sporting events or any where where security is required.
It is sensitive enough to detect metal objects the size of a 25-cent coin (Dia 24.3 mm) from 60 mm.
It sounds a high-pitched tone (or vibrates) whenever 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.
A de-sense button reduces the sensitivity by about 50 percent, so you scan near floors, which contain large amounts of steel reinforcement, or only for larger objects.
Visual indicators: Tri-Colour LED status indicator: Green LED power on indicator, Red LED Indicator lights when the Body Scanner detects metal, Amber LED flashing when battery is low.
