Tripwire Odor Imprint Devices (TOIDS)

Tripwire Odor Imprint Devices (TOIDS) serve as training aids for explosive detection K9 teams when access to live material is not practical. TOIDS offer real explosive odor but are absolutely INERT and DO NOT present an explosive hazard. TOIDS are non-controlled and require no licensing or special storage. TOIDS have been designed to be an inexpensive and unregulated alternative to live explosive aids. TOIDS are constructed with a laboratory grade filter material that contains microscopic odor particulate matter, which has been suffused via a proprietary method, which is permanently sealed between two (2) aluminum discs utilizing rivets – NO adhesive is used. Our devices are prepared and packaged in accordance with FBI safe-handling techniques to prevent cross-contamination.

TOIDS have been extensively tested by third-party agencies and results have shown that odor remains active for approximately 90-120 days* for conventional and 30-days* for HME odors, under normal use with proper storage and handling. TOIDS are packaged and shipped in patented and state-of-the-art OPSAK® odor barrier bags by LOKSAK®. These resealable polybags boast of a hermetic seal and are certified waterproof to 200 feet (60 meters). Any item placed inside the OPSAK® bag remains impervious to the elements and retained to the highest degree. The OPSAK® bag offers an absolute airtight seal preventing the re-entry or release of air and microorganisms, therefore minimizing breakdown and decomposition. The Tripwire Odor Imprint Device is currently in use by U.S. Special Operation Forces Multi-Purpose Canine (MPC) Teams and law enforcement agencies throughout the United States.
