I just discovered what I've been looking for for a long time. It's faster than tree steps, lighter and smaller than climbing sticks, weighs about one pound and can fit into my back pack. Rock climbers use these things to scale vertical rocks so they are load tested and safe. I just ordered two of them which should get me about 14 feet up into a tree. I'll use these with my Trophy Line Tree Saddle to have the ultimate lightweight versatile quiet mobile hunting system. My plan is to strap two of these to the tree and climb up. I'll be able to get up into the tree quickly and quietly. What do you guys think?
