Sniffex
Sniffex and Sniffex Plus are fraudulent explosive detection systems produced by Homeland Safety International. == Performance == An article in The Dallas Morning News in April 2007 describes Sniffex as a "divining rod" and states that "In a test by the U.S. Navy, Sniffex didn't register when two trucks passed within 20 feet, hauling a half ton of explosives." The Navy's counterterrorism technology task force tested Sniffex and concluded "The Sniffex handheld explosives detector does not work." Despite this, the US military bought eight for $50,000.
