Product review - the Coleman SportCat Catalytic Heater is a safe, convenient way to warm your tent on those chilly nights. A single 16 oz. propane cylinder can provide heat for up to 14 hours at 1,500 BTU. It's easy to carry, and it comes with a sturdy stand. SRP $38.00 and $43.00 (with electronic ignition).
