Promar Crab Snares Crab Gear - The Promar 6 Loop Crab Snares are made of vinyl coated wire mesh. Catching crabs on a rod and reel is a load of fun with this series. The snares come equipped with 6 soft monofilament loops and allow the snares to close with less effort and cinches down to secure your catch. Bait up the bait cage with fish scraps or your bait of choice and cast out to rocky structure. Once you feel a tug, set the hook and reel in something other than a fish!
