I finally got most of my SRT (single rope technique) equipment together. First tests on a nearby quarry and a small bridge.
First had the Petzl STOP descender device, but after finding out that this thing does not STOP at all (it’s not belaying you unless You hold the rope) I bought the Petzl I’Ds. With this one and a hand ascender it’s very easy to climb up everywhere where You also have a wall to push the feet against.
After being confident I went to the first nearby limestone cave that had a 5+ m slippery drop and i still live. Success!
