I picked up a Wolf Master ram snare. I wanted the #2 size but the place I shop at I was lucky they even had that. The #2 goes up to a 12 inch loop and the Wolf Master goes down to a 12 inch loop so i figured i would be ok with that. I blocked off a small area with square bales in the bush across from the driveway where we dump all our table scraps. I left a 2 foot opening for the yote to walk through with the snare set about a foot off the ground. No luck yet but I'm not sure if my Dad is checkin the trap for me faithfully. i have never heard of the collar um trap but i will look into them also for future reference.
