It was a cable friend (flexible friends, so no shaft) break off. The cable attachment to the friend body is always a weak point. Flexible friends can be placed in horizontal crack and the cable should not break off when catch a fall. It is a manufacturer’s fault if the cable breaks off. For the cable itself (not the cams mechanism), it will be a very similar catch as shown in the picture.
The cams may pop-off due to soft rock or too shallow so the cams chip the rock edges, but it depends. Anyway, I am scared to death, I won\'t put the placement like the picture shown.
To travel in all directions, I learn whatever skill necessary.
