When I started, I use binder twine with slip knot. Hung by one leg. Skun for years with one back leg. Then I bought first gambrel in pic #1. Then tried different rigs since then.
Warm days trapping before work, I would skun at the end of the line. Cord tied to choker, hung by one back leg. Cord over limb, end tied to tree.
Goose, if I find a faster way to do things, I change. Especially during fur season.
I built a prep table to ring ankles & legs. Turn around, there is the gambrel. If I save one or two minutes skun'n, that add up to more sets I can make or more sleep.
That's why I posted about gambrels. Alot of guys overlook a speedier, time saving way to hang a critter, .
