D Ray East wrote a question about Black Diamond Super 8 Belay/Rappel Device on January 20, 2012
One thing that might be really nice is to show how a rope goes through a figure eight belay device. just a large photo of a figure 8 and then show the line coming down from the top of the rock going through and around the figure 8 and then out the bottom and showing the tag end going to the bottom of the rock.
Also the quick and easy way to hook into the figure 8 with a rope. show a single line starting at the top then the device bext to the line. then how you hook to your harness and the rope and the device to get them to all work together and the way it actually works and why. You might get some total beginner to give some thought to joining in. dray.
