Army Contraband Detector
A contraband detector finds material concealed inside a structure rather than carried on a person: goods packed behind panelling, inside tyres, in vehicle voids, in walls and in cargo. It reads the density of what is behind the surface, so an operator can compare a suspect area against a known-clean reference on the same vehicle or container. Configuration depends on what is being searched and by whom, so the unit is built to the specification supplied with the enquiry rather than sold to one fixed build.
