I was in my friendly local gear shop today and (in addition to the usual eighty euro Miura Laces) they were selling off some Dragon Cams for forty euros apiece. At times like this one doesn't hesitate or ask questions; I went straight for my wallet.
My question is this: I was studying the instruction leaflet in the U-Bahn on the way home, and I have no idea what Diagram 10 is trying to say to me. Couldn't see any reference to it in the text. It shows a cam with the sling extended and two krabs pulling in opposite directions. It gets a tick, so evidently it's ok/recommended for something. But what?
