*Recently upgraded design now includes a 12v 5A rechargeable battery system to enable our new air raid siren. This increases the detonation audibility to over 1/4 mile outdoors with varied terrain!

Our flagship device, a.k.a. "Fat Man", is a durable yet complex explosives simulation device used primarily for paintball and airsoft scenario play. This device is robust and realistic enough to be used for military and law enforcement bomb plant-and-defuse missions. Since our devices use non-lethal means of detonation and disarm notification, the risk of injury is eliminated but the scenario possibilities are limitless. Let the opponent know from up to a mile away outdoors that you've just destroyed your target with our multiple high-decibel sirens.

Originally designed for and installed within a 50mm ammunition can, Fat Man can take a beating. Dropped it while running to your objective? Fat Man will perform. The outer lid protects the interior screen and keypad from physical damage, and its impact-resistant body can even survive a 10 foot vertical drop onto a hard surface.

Fat Man's internal components and electronics are secured safely within the metal body of the device, providing the necessary defense against the elements and the physical exposure of scenario play and training situations.

Does your scenario play ofen have players that aren't as aggressive as the gameplay calls for? Add a timed bomb device to create a sense of urgency to the situation. Whether you use the arm/disarm feature to stimulate players to engage on the battlefield, or just use our bomb props as a round timer, those slow players will have in incentive to engage in the action.

The versatility of our devices allows us to custom program features into your own personal bomb prop. Customize codes, detonation time limits, messages and more. Enter the battlefield with a simulated expolosive device that works exactly how you need it to. No more limitations with cheap timers, quieter sirens, and inferior craftsmanship.
