What heater to use for ice shelter?

[StillHuntin]

I have an old "cooker-heater" style Mr Heater for the ice and it's ok in a Fish Trap shelter. I use a Big Buddy for hunt camps (base camps elev at 7400 and up) it produces much more heat and has a blower. I had a problem with the Big Buddy this year and called the customer service desk. The heater needs a filter if you use a remote tank (but not for the 1lb bottles). They asked me to send mine in and they replaced it with a new unit. Mine was 2 or 3 years old. Great service.
