Developed for military / tactical training use and similar to real landmines, S-Thunder's IGG-3 Series rechargeable dual use gas powered landmine shell is triggered when foot pressure is applied to the gas landmine and activates with a loud bang to simulate an explosion (spraying water or powder) when the foot is released. Durable, reusable, easy to maintain and operate, the IGG series utilizes S-Thunder's patent pending technology to offer a realistic simulation of a battlefield experience. This unit is compact in size and can explode with 10 lbs of pressure allowing for a 90dB sound volume (with CO₂) and a 3.5 cubic meter blast volume. The unit is shipped with a cloth bag for convenience. To charge the unit with CO₂ gas, S-Thunder's CDC series CO₂ cylinders with adaptor is recommended (Sold Separately)
