Hi Cameron, valid point to raise - I just wonder, would Petzl advocate a technique for a counterbalance that could / would foreseeably be used on a “live” set of ropes if they felt there was a risk of the toothed device damaging the rope? The point Ally raised about not wanting to use a piece of kit that most techs won’t have on the job is valid. Given that a toothed ascender confirming to EN567 will not damage a compatible rope below 4kN, we’re safe to re-anchor using it. Good comment though and good to have constructive debate.

This is great

Hi Alex, SPRAT shouldn't have an issue with two person loads on a hand ascender as one of the techniques Petzl recommend for lifting a casualty out of a Croll is a counterbalance using a hand ascender as an anchor, this places a two person load on the ascender. Hopefully this helps.

Can you do that for Sprat, two person on a tooth device rescue.

Can you use laces from your work boots as a substitute for cord if you don’t have any on site?

So, are you coming down with the casualty, on the hope held by the hand ascender?

3:01 ASAP to face)))

Nice

Is it possible when you get down to the knot on the working line that you clip an extra backup ontop the descender, then clip an extra descender to where you have backup, and continue descender from there... instead of using a toothed ascender as an anchor point. Then when you reach the 2nd knot (where the former backup has been, and the descender is now), you can switch over again? Also, can you also use a non-toothed camming device (ie. Camp Goblin, Petzl Rescucender, Beal Monitor, etc.) as an anchor point in lieu of the hand ascender?
