I need some help in finding a climbing aid for my tree stand. I use a portable climbing stand that I made with the help of my uncle. You simply put your feet in the straps on the platform and bear hug the tree and pull yourself up like a inch worm. I know they make climbers that make it so you do not have to hug the tree, but I can not find them any where. Does anyone know were on the internet you can buy one of these climbing assist?
