That's why I love the Fall Guy safety system. It hooks on at the bottom of the tree and NEVER comes off until I unhook it when I get down from the tree. I am switching to climbers due to theft in our area, so I have 2 of them for sale in the classifieds if any one is interested. They have been used about 4 or 5 times. They retail for $85 in Cabela's, I'll take $60 each plus shipping. I am telling you, there is no substitute if you are hunting a hang on!! Please, please everybody be careful and pay attention - ALWAYS!! Thank God he will be okay.
