Ive done lots of trapping years back. I caught an 80 pound beaver once. Steel leg traps is what I used. I was never a fan of snares because dogs and cats can end up in them sometimes especially if you bait. I managed to make Christmas money several times. Victor leg traps are one of the better brands out there. Jump traps and long springs. Under water or dry land sets. No.1 for muskrats, No.2 jump or long springs for coons, Otter or Fox. No. 4 for Beaver. Conabear traps are killing traps and can kill a large dog if placed improperly.
Trapping is an art form where study, trial and error, careful planning and knowledge of the animal your trapping is valuable. Go out with a seasoned trapper is one of the best things.
