Detectors and scanners screen for potential threats and alert security personnel to the presence of metal or explosives. Metal detectors locate metal in non-invasive body searches, packages, or in the ground or underwater. Explosive detectors identify explosive compounds. Security screening stations use handheld and walk-through metal detectors to enhance safety in a facility. Ground search metal detectors help find lost or hidden items. Carrying cases and tents shield sensitive scanning equipment from sun, rain, or wind.
