HHMD - Hand-held metal detectors are the most commonly-used type of metal detector. They are
inexpensive and come in variety of form factors, from baton size to cell-phone size. The HHMDs
generate various frequencies of time-varying magnetic fields and different magnetic field
strengths. Handheld metal detectors consist of two parts, a transmitter coil that creates the
electromagnetic field and a receiver coil that observes electromagnetism.
An electromagnetic
field will be generated around the transmitter coil which goes around 20cm from the handheld
metal detector. When the metal detector is searching over a subject’s body, if the hidden metal
object falls into the generated electromagnetic field then it will trigger an alert for the operator.
SCS handheld metal detectors provide multiple alarm indicators, visual LEDs, selectable alarms,
and vibration. Our handheld metal detectors are lightweight, handy in design, and come with a
standard 9v battery that will provide continuous operation for a long time.
