MyFishFinder.com Just like iceshanty but warmer
The regular portable buddy will do the trick. I use one in a 6x8 and have yet to be cold down to -14. Do yourself a favor though and get a big bottle and the adaptor...buying 1 pound bottles all the time gets old.
So I just got a Cabela's 6x6. Probably only going to bring it along to get out of the wind on really cold days or if im gonna do a lot more jogging than tip up fishing that day. Would the regular buddy heater be big enough? Fleet farm has a good sale on both right now. Like I said I won't be using it all the time so I don't know if it's rally worth it to me to buy the big buddy
