The FireDisc Cooker was designed to use with a 16.4 oz. disposable propane canister for maximum portability, but you can also use your FireDisc Cooker with a refillable 20 lb. propane tank using our propane tank adapter hose with gauginator. The gauginator provides easy ability to see level of propane in your tank. This comes in handy if you’re going to use your FireDisc all season in deer camp, all summer at the cabin, on a long weekend or on an all-week trip.
