PA- I have used a thermacell for several years, when they first came out. I own three of them. They do have a odor, however so do we no matter how hard we try to conceal it with all the steps and gadgets that we use. If a deer gets down wind of use there is a good chance that they will bust us so the small amount of odor out of them does not bother me, it sure beats setting there with all those bugs swarming around my head.
Mulie- I also have been shooting my bow, might as well kill my target for a while till I can set in a tree. I practice out to 50 yards but want my hunting shots to be 30 or under. I would take a shot out to 40, IF everything was in my favor to take the shot.
(Calm deer, true yardage known, and no cross wind that would effect my arrow.)
I have never taken a shot past 32 yards and have shot them as close as 5 yards on the ground.
