RE: Safety Harness Question... Ascending/Descending
It's exactlythe same thing that I linked to in the HSS lifeline and the directions I outlined for you for the home made version.
A long length of rope tied to the tree above your stand and at the bottom of your stand. You hook into the prussic knot and slide it up or down as you are climbing up and down the ladder. It really doesn't get any easier than this.
A linemans belt is used while hanging stands or taking them down not for climbing up and down the ladders while hunting.
