Red and green color may vary. Cold campsites and frozen lakes call for the warmth of a Big Buddy heater. For your next excursion, the Big Buddy will keep you comfortable with up to 18,000 BTU of heat. Swivel regulators make for easy setup; just screw on two 1-lb propane cylinders or connect to a 20-lb tank using Buddy accessories. The 450 square feet of coverage makes any ice shanty a sauna and any deck a sunroom. With the heaters' registered Life Safety System you won't sweat too much knowing the oxygen depletion sensor, thermal shut-down system, and tip-over switch are keeping you safe. For all of your indoor and outdoor adventures, the Big Buddy is there for you.
