Spur Ascenders

[DMc]

True, Kevin. But big is a relative term. A 36" to 42" diameter tree is what I would considered an average big tree for me and they are not particularly challenging for "tree length" gaffs. If you can set a top rope, they become even easier.

It only takes a couple of minutes to swap out to gaffs once in position and it gives me a chance to breathe a little after a long climb without letting my ground help know I'm gassed
