The HotShot™ from BullEx employs digital flame technology and Bullex’s SmartExtinguishers™ to allow users to dynamically interact with digital fire. The self-contained HotShot fire safety system enables realistic training indoors or outdoors. If trainees fail to use proper technique, the flames respond accordingly; flames can diminish, grow gradually or even reignite.BullEx Digital Safety,, (888) 4BULLEX
