Red seems to be quite confident that you can get this buckle crazy tight. This has not always been my experience. With a smooth bark tree (like beech or poplar) that's pretty symmetrically round I've been able to crank it really tight. On trees with shaggy, loose or really thick bark and on trees that aren't perfectly round I've struggled to get the buckle as tight as I would like. It still works, but there's more play in the steps than I'm happy with. For reference I've hunted with this buckle about 10 times and I've been happy with the tightness probably 6 or 7 of those hunts.
