The benefits of
hand-held metal detectors
Hand-held
metal detectors are designed to safeguard
security-sensitive areas like schools,
courtrooms, corrections facilities, sports
events, businesses, nightclubs, bars and other
public areas and events. They are used along with
walk-through metal detectors. Construction crews
and woodworkers also use hand-held metal
detectors to find dangerous nails or other
metallic debris in reclaimed building materials
and trees.
A recent study proves that hand-held metal
detectors are just as accurate as X-rays in
finding coins and other metallic objects
swallowed by children. They are cheaper and
radiation-free, are usually lightweight, highly
sensitive and require little maintenance. The
special shape of the sensitive surface makes
operation of the device easy, unlike portable
metal detectors with ring transducers. They come
with 9V batteries or rechargeable NiMH batteries.
Hand-held metal detectors are most commonly used
for body searches for weapons in crowd control,
and checking parcels and letters. The Garrett
Enforcer G-2 is the smallest body scanner and
sensitive enough to detect even the smallest of
knives or guns. The Super Scanner. It can detect
hatpins as small as 1 inch.
When hand-held detectors are switched on, a red
signal pattern in transmitted from the coil to
the ground. When the signal comes in contact with
a metal, it interrupts the signal and the
detector alerts the user with an audio signal and
flashing lights. Hand-held detectors are of
various types – commercial, professional, all-purpose,
beach, gold metal, relic metal and 2-box deep
searchers.
