There are times, especially when operating the DryFire system in a noisy room, when the Voice Release system releases unwanted targets because of “the background sounds.” Therefore, we have included a Hand Release Cord in the standard “Squad Packs” because we know the Squad environment (especially in a clubhouse) can become quite noisy. The cord is 20 feet long and plugs directly into the back of your DryFire unit. The moment the cord is plugged in, the Voice Release circuit “goes to sleep” and later you can return to Voice Release by simply pulling the plug.
