I do not strap my climber to the tree. After I get everything at the height I want it, I sit on the bar for the top half and use the leverage to dig in further and then bounce a little on the bottom half. I never have knock it loose and sometimes it requires some effort to get it loose for the climb down. I always climb with a harness. As soon as I steep in the stand, I attach the harness as high as it or I can reach, climb until my stand reaches the strap, loosen it and slide it up the tree, tighten and repeat. The reverse for going down. Just make sure you tie the two halves of the climber together with about 4 feet of line incase you drop the bottom half.
