Big Heater

Great heater for deer blinds, low setting is more than enough for the average blind. Almost too big for a single person blind.

Great backup heat

I bought a buddy flex this past months for a backup heat source. I tested it out and it was easy to set up and worked great! I plan on buying the cooking attachment asap.
