Those were days when we simple tree climbers were trying like hell to figure out things the cavers had long since begun to develop. Stole a bunch of ideas from them, didn't weI tried single rope technique in the early 1970s. Quite simply by tying a taughtline hitch to a single run of manila rope. My attempt failed miserably. Low and slow.
Despite the fact I figured it could be done... if by some means the friction on the hitch could be eased enough to make it run smoothly on the rope. Instead of herky-jerky, and the thought of using roller chain in the system come to mind. 30 years later Morgan Thompson's Unisender come to be. It was the incarnation of what I was imagining in the 70s.
Many variations have come about since.
In the early 80s I bought some Gibs Ascenders to reach the old-growth canopy. Although not close to the arborists methods of single line technique all of it has made dramatic improvements over the years.
. You and I, Jer...and some others, not many but for sure we were not the only ones...began the journey that today's SRT equipment designers/developers have now brought to full fruition.Did the ninja do any SRT?
Miriam and I discuss a Busman's Holiday, post covid... I'd show you a trick or two, Cory.
