An ADE 651 device in 2016. The ADE 651 is a fraudulent bomb detector [1] produced by the British company Advanced Tactical Security & Communications Ltd (ATSC). It was claimed to detect many substances, such as drugs or explosives, from long distances.
A Y-shaped twig or rod, or two L-shaped ones, called dowsing rods or divining rods are normally used, and the motion of these are said to reveal the location of the target material. The motion of such dowsing devices is commonly attributed to random movement, or to the ideomotor phenomenon , [ 7 ] [ 8 ] [ 9 ] a psychological response where a ...
A variety of technologies are used to detect landmines, improvised explosive devices (IED) and unexploded ordnance (UXO), including acoustic sensors, animals and biologically-based detection systems (bees, dogs, pigs, rats), chemical sensors, electromagnetic sensors and hyperspectral sensor analysis, generalized radar techniques, ground ...

Many such devices contain non-functional circuitry or naively constructed approximations of radio transmitters. A few do have functional circuitry, putting out a weak signal with a function generator or a simple timer circuit, but are still largely useless in comparison with a coil-based metal detector; others have been found to contain intentionally obfuscated or completely superfluous ...
When the visitor held one end of the rod and von Graeve the other the rod bent towards the coin but not as violently as before. [1] The motion of such dowsing devices is generally attributed to the ideomotor phenomenon, a psychological response where a subject makes motions unconsciously. The scientific evidence is that dowsing is no more ...
The Quadro Tracker, also known as the Positive Molecular Locator, was a fake "detection device" sold by Quadro Corp. of Harleyville, South Carolina between 1993 and 1996. . Around 1,000 were sold to police departments and school districts around the United States on the basis that it could detect hidden drugs, explosives, weapons and lost golf bal
