I dont use the climber now either -for other reasons-- used to tie a rope between the bottom and top sections just long enough to allow the climb up without gettin in the way --if there was a slip on the bottom it could only go down a short distance.
A lot of us have been left up there clinging to the top half -lol.
Seems that all tree stands have their 'issues' I HATE the first trip up that shakey ladder stand to affix the top to the trunk. Now tie a rope around the tree and the top section and kinda try and slip it up the trunk when setting up. Felt like it was gonna tip over more than once on that first trip up.
