LOOP METAL DETECTOR (LMD)
LMD has been developed to detect of metal objects like gun or bigger, but not
small like watch, carried by man through door embrasure.
LMD is inexpensive variant in comparison with traditional metal detectors. LMD
can be hidden from people viewing.
LMD consists of transceivering antenna and electronic unit.
