Never had any trouble getting all the deer I wanted when I used to do this. In fact my second biggest buck was taken from this climber. The climber had been being left on this same tree from early Sept.(thats back when I had that bow hunting affliction) until the third Sat. of Oct.(opening day of rifle)when the buck was taken. It was back before scent coverage was in vogue.
It has been my experience you can put anything in the woods. You just have to do it plenty of time for the deer to get used to it before season.
