Read Ragnar Benson's Survival Poaching. Learn to make your own, either out of "stranded" copper electrical wire, for small game, or aircraft cable for big critters. You hook the elk-moose-bear snares to a big drag log, like 100+ lbs and let them exhaust themselves moving it, while creating a trail that literally a blind man could follow. Snaring deer and larger critters is illegal, by the way. It's a shtfONLY sort of thing. The cable needs a "one-way" device, which Benson shows you how to make, out of a small pc of angle iron. I'm sure that the guitar strings would too, as would piano wire, etc.
