Was that a Creedmoor or PRC snare?
Thompsons best i've used ,120 inches,1XX.I like to use 3/32 " 7x7 air craft cable some like 5/64 " . The shortest length that I use is 8 feet long ,so that a coyote has plenty to tangle up and chock themselves faster . You can buy the parts from a trapping supply house as well as buying premade snare's . O'Gorman , Minnesota trappers supply are a couple of places to look for books and or supplies .
Nice set up,will keep in mind.I sure like snaring and use a killpole wit it. 5ft 5/8 rebar for coyotes 1/2 rebar for beaver with big washer weld on. And about 30 inch #9 wire wrapped around 2 or 3 times. Hammer it in ground hook snare around rebar and thru washer. U dont have to tie anything off. U have snare support and anchor all in one .Plus if it's a good place leave rebar in place. For the yrs to come. U just need to bend the wire back. The one in picture is for beaver or coon.
Great job,you will definitely see an increase in,beneficial game species,i surely have.In Texas Hill country and in the last 3 years have trapped or snared 77 coyotes. They were making a big buffet out of my deer, but putting a dent in them.
