Handheld Raman for Explosives Identification
James T. Thurman, associate professor at Eastern Kentucky University and former Chief of the FBI Bomb Data Center, conducted an independent evaluation of FirstDefender as a screening tool for field ID of commercial, military, homemade explosives, and explosive precursors. FirstDefender returned an 89% positive ID rate (including mixtures) with no false positives. Contact us to obtain the full test report.
The above First Defender is in the arena with the Cdex ID2, not the G4, lol.
