This video is a test of the ADE 651, description below: "The ADE (Advanced Detection Equipment), is a revolutionary tool in the effective detection and location of Narcotics (drugs), Explosives, and specific substances at long-range distances. The first tests we conducted showed an ?indicative? detection range of approximately 650 metres and hence, the first version was called; ADE650. However, over the years, the ADE developed and its current model, (ADE 651, 680) has more enhanced features making it a more useable and more effective device. How does the ADE work? The ADE works on a principal we have termed as Electro-Magnetic Attraction. The principle for long range detection is based on the substance excitation that needs to be detected, with an electromagnetic field that propagates on a long distance and is not disturbed by the "electromagnetic noise" from the environment generated by the RF transmitters and other electronic equipments that use electric current or electromagnetic waves. Simultaneous Detection of Multiple Types of Explosives or Drugs As mentioned, the ADE651® incorporates electromagnetic attraction [EMA] technology to target specific substances. It can accommodate multiple substance detection through the use of our proprietary sensor-cards to detect a broad range of explosive or drug [narcotic] materials. It can narrow-down this to identify a specific substance by removing the individual detection cards from the unit after first detection, until the ...
