What heater to use for ice shelter?

[RyanCreek]

I use a Coleman black cat catalytic heater. I've been very happy with this heater so far. It's a solid heater, compact, simple, not expensive, and works at any altitude you are going to ice fish at. You can get the one you have to light, like mine, or an upgraded one with an electric start. Like any heater, it consumes oxygen, so if you get woozy let some air in. The Mr. Buddy has a little more BTU's though.
