The 12 Gauge Tactical Distraction Training Block Device is a safe and useful device for police training. The device will produce a loud sound effect from the triggering of a special 12 gauge safety shell case (filled with urethane energy absorbing foam) to simulate officers under fire in a realistic way. An option for an alternate version accepting only a 20 gauge safety shell case is also available. A simple pull cord triggers the device when desired in the training exercise. All parts manufacturing is done at the Lamperd Less Lethal plant in Sarnia, Ontario, Canada.
