The GT200 is a fraudulent device that "helps" people find drugs and explosives. Actually, the GT200 is an 21st century divining rod.

  • Mexico... a few years ago
  • Mexico... today
  • Mexican drug war
  • How does the Mexican Government protects its army?
    • Giving them the GT200:
      • A so-called “remote substance detector”
      • Made by UK-based Global Technical Ltd
      • It “detects” various substances including explosives and drugs.
  • More about the GT200
    • The GT200 has many iterations: Sniffex, ADE651, HEDDI
    • The UK Government has banned the export of such devices to Iraq and Afghanistan
    • The government of Thailand spent $21 million on the GT200 but has now accepted that the device is completely ineffective at detecting explosives
  • How does it work?
    • The GT200 consists of three main components:
      • A swivelling antenna
      • A Plastic handgrip
      • Sensor cards
    • It requires no battery or other power source and is said to be powered solely by the user's static electricity
  • In other words...
  • So how does it actually work?
    • The antenna is not stable
    • People move the device unconsciously (ideomotor effect)
  • What about the media?
    • Mexican media has mostly ignored this issue
    • A few science promoters have written about this
    • The most reliable sources however: Mexican bloggers
      • Blogger Andrés Tonini has done lots of research
  • Asking Questions
    • Tonini has been asking governmental agencies why they purchased the GT200
    • Some agencies have replied
    • PEMEX (Mexican Oil Industry) explains that there was a committee (names provided) and tests where made: the GT200 is effective, they concluded
  • My Question
    • Is this GT200 issue a matter of corruption or lack of knowledge on how to perform scientific tests (like the double-blind method?)
  • What can we do?
    • Keep blogging!
    • Be bilingual
    • Be nicer
    • Also: We need a celebrity (there is no Spanish-speaking Richard Dawkins or James Randi)
