In this lesson, you will learn how to progress safely along a retrievable handline, used to reach an anchor while allowing the rope to be recovered afterward. You will discover how to move efficiently by correctly using your two cowstails on the two rope strands, while maintaining stable balance and support on the rock or the rope. The lesson also explains how to pass intermediate points by transferring the cowstails one at a time in order to remain constantly secured. This technique is essential for moving safely through exposed traverses in a canyon.
