Buddy heaters work great in the blind. The only noise it will make is when you first fire it up when you "click" the igniter. When its running its quite. I have used the buddy to heat a camper, wall tent and used it last weekend in my Double Bull Blind. Had my son out there with me and you could sit in there with a t-shirt on. It was so nice in there my son fell asleep until i woke him up when a coyote came in.

You can get them for around 79 bucks now on sale here and there if you take some time to look.

You wont be dissapointed
