The Basic Vertical Training Student Manual can be obtained here:http://caves.org/section/vertical/2012%20Basic%20Vertical%20Manual.pdf (Note: the Figure 8 rappelling device is no longer used because it, and other things like it, cause a twist in our ropes.) Never learn to do rope techniques by yourself. Always have someone with you that can get you down and safe. Vertical caving is not the same as rock climbing and our equipment is different, both are dangerous, so get training.
