A must for canyoneering
this is a must for technical canyoneering in my opinion. i have used an BD act, totem, etc. This is just solid, and easily adjustable. got me through heaps canyon, which would have been a pain to have dealt always taking off the device and possibly loosing it in the holes. you don't have to undo it to take off the rope, and it won't fall off either. loved it.
