The petzl pantin and crol foot and knee ascenders together with the zig zag is phenomenal on SRT, im 40 now, i took a long break from climbing after breaking both femur in a bike accident, and moving up to contract manager i did a lot less on tools, especially tree stuff, but ive decided to go self employed so doing a lot of tree work, and the petzl knee and foot ascender are a god send, you can get up very large trees in no time at all without breaking a sweat, i bought my 12 year old a petzl harness and its so self intuitive, even he can climb using them (without the tools of course).

If you combine the foot ascender with a knee ascender on the other leg, you’ll be flying up there 👍

A hand ascender or hitch cord with a petzl roll clip attached to either or is excellent mechanical advantage for feeding the tail of your cord from below your zigzag, into the rollclip. Now attach your foot ascender. You won't advance the tree faster but you will be able to do it with much less effort. Give it a try🤔😁

How about attaching the ascender as you did but clip a small pulley to it, put the tail of your climb line into it then clip your foot ascender to the tail coming out of the pulley.... :) :) It won't be faster but it will be super easy ;)

I actually used it as a Rad system today instead of the petzel ID.

Wow... !!! My best friend, You Great Good... !!! I wish you every day of your development. Best Relaxing +thumb up3!

Yeah honestly double rope is really going out of fashion single rope is the way to go with a foot ascender then knee ascender and bass tie your anchor .

this was painful and exhausting to watch.

Double rope technique is going out of fashion single rope is the way to go with a knee ascender and a foot ascender and base tie

Much better techniques of climbing without having to use just your arms like that w the zig zag …
