This is an amazing piece of safety gear. A lead climber is able to safely climb without a belayer when setup correctly. The Silent Partner uses a hitch that slides until loaded at which point the system will lockup and arrest the fall of the climber. I am looking forward to training in the use of this superb piece of equipment. Once I have picked it up from the store I hope to get a number of uses out of it this climbing season. I had special ordered this equipment so soon as it arrived at the store my mate who works for them texted me the photo. I look forward to posting on it again once I have had a good go with it.
