Looks like a good setup, Question how do attach it to the tree? is it just a rope tied around the tree? you can go 360 degrees around the tree? Then it would be better then a stand, you would never have an awkward angle to shoot from.
I'm thinking patent, that is ingenious. I would look at marketability.
Can't do it. We stole the idea from a friend we hunt with,we have refined the design though.
