The High Heat SmokePistol is different from the standard SmokePistol in that the smoke chamber is isolated from the electronic control. This is for use in very hot conditions. The SmokePistol BBQ smoke generator is great for hot smoking and cold smoking. Just light a cartridge, insert it into the SmokePistol and you have continous smoke for 4 - 5 hours on a single cartridge, Cartridges are available in 10 real wood flavors and are made of real wood with nothing else.Quickly attaches to any BBQ grill or smoker. The smoke output is fully adjustable with an electronic control. Can even be hooked up to a cooler for cold smoking of fish, cheese, etc
