The Silverback
A lot of the mechanical devices were specifically designed for rock climbing and caving. In tree care there is a lot more debris, weather extremes and chances for abuse than in the recreational arena. I do use mechanical devices both in rock climbing and in tree work. There are some that I feel are best left to recreational climbing, but that is only my opinion. I like using rope on rope on my climbing line to secure me in the tree. This easy to teach and works well. For work positioning lanyards mechanical devices are far superior. You are usually the most productive with what you are comfortable with. This really reduces the mental strain during the job.
