Not only wear one while hunting out of the tree but while climbing up or down aswell.. My Dad almost had a bad accident last year. He has a new ole man climber and a pin worked loose and while he was climbing down the cable slipped and the top part of the climber gave way. He fell backwards luckily caught by his safety harness. You never know when something can seriously go wrong. I have been guilty of hunting without one and climbing without one, but after what happened to my dad never again..

I am glad to hear he is Ok I bet that was a scary lesson for him.
