Sling Dynamics

[Tim Watts]

This is actually talking about climbing and taking dynamic falls, something that we should never do when caving. But it still shows the importance of knowing about the gear and techniques you're using. I.e. if life-lining using a slack sling in the system, or possibly using a sling as a back up anchor that isn't equalised properly.
