Oh, okay.
I thought it wouldn't need to withstand too much tension if it allowed the ascender to advance the hitch upward, much like the micro-pulley allready does only the force of lift would be transferred to the ascender and not a "tailing" pulley. There's a lag distance always from my pulley, this way would take that slack up. Just wondering.
Good thinking on the invention though. As far as a locater I identify with that big time. Lost a bunch of stuff today...non-mowed ground cover and thick as pluff mud. Might go back with a metal detector but a pole saw section? Can't believe my son lost it.
