Snaring is a great way to get meat while you sleep and is not all that complicated. The hardest part is coming up with the snare.
The snare need not even be triggered. In fact, most people I know who snare just arrange things so the critter goes through the noose and tightens the snare as it tries to get away. I knew a woman who once snared an Elk.
8-10 feet of aircraft cable can take you a long way in snaring. Find well used trails and look for openings in the trail where the critter has to pass its head through first. Anchor your snare so the struggling animal will not get loose. For larger game a tree makes a nice anchor.
You can set as many as you have and it’s best to do so to increase odds.
Don’t practice this in an urban setting as you’re more likely to catch the neighbor’s dog than a deer or coyote.
