Thanks for the advice everyone. I tried my climber tonight and it wasn't that bad. It took a few minutes to figure out the mechanics, lol, and I had a few scary moments but thank God I was wearing my safety harness on the way up or I would have been toast! I never lost the platform end but the seated end did end up sliding on me a couple of times and if it were not for my safety harness I would be seriously hurt or worse. It is going to take some more practice but it will not be long before I am setting up in the dark and climbing trees in a jiffy I think! I also tied both ends together with the rope that it came with but I may get another one and have two of them just in case!

Question. I thought of maybe taking an extra D ring and hooking the seated end up to the rope on the tree that holds the safety harness. That way if both ends slip they won't slip to far. What do you think?
