VirTra's patent-pending Threat-Fire device safely simulates the pain of hostile return fire with a 300-millisecond electric stun (adjustable to 2.5 seconds). Enemies often try to use the element of surprise and this training accessory is being used worldwide to better prepare trainees. The Threat-Fire II is a clip-on return fire simulator, similar in function to the Threat-Fire belt. However, the Threat-Fire II is designed to clip onto an officer's duty belt for maximum efficiency. The Threat-Fire II is not only small, lightweight, and designed to be unobtrusive, but it is also rechargeable and compatible with VirTra's wireless system.
