  2. Metal detector - Wikipedia

    en.wikipedia.org/wiki/Metal_detector

    A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped pickup coil. When the coil nears metal, the control box ...

  3. Rapiscan Systems - Wikipedia

    en.wikipedia.org/wiki/Rapiscan_Systems

    Rapiscan Metor walk-through metal detectors stem originally from Outokumpu, which was one of the first companies to develop walk-through metal detectors for security screening. The systems were originally adapted from metal detectors used in the mining industry to locate parts of broken drill bits in minerals on a conveyor belt. [5]

  4. Induction loop - Wikipedia

    en.wikipedia.org/wiki/Induction_loop

    A different sort of "induction loop" is applied to metal detectors, where a large coil, which forms part of a resonant circuit, is effectively "detuned" by the coil's proximity to a conductive object. The detected object may be metallic (metal and cable detection) or conductive/capacitive (stud/cavity detection). Other configurations of this ...

  5. Airport security - Wikipedia

    en.wikipedia.org/wiki/Airport_security

    A technology released in Israel in early 2008 allows passengers to pass through metal detectors without removing their shoes, a process required as walk-through gate detectors are not reliable in detecting metal in shoes or on the lower body extremities.

  6. List of metal detecting finds - Wikipedia

    en.wikipedia.org/wiki/List_of_metal_detecting_finds

    This is a list of historically significant items found by metal detecting method, only excluding magnet fishing finds, since magnet fishing is usually considered a distinctively different and separate hobby from traditional metal detecting.

  7. Magnetometer - Wikipedia

    en.wikipedia.org/wiki/Magnetometer

    Magnetometers can be used as metal detectors: they can detect only magnetic metals, but can detect such metals at a much greater distance than conventional metal detectors, which rely on conductivity. Magnetometers are capable of detecting large objects, such as cars, at over 10 metres (33 ft), while a conventional metal detector's range is ...
