I use the snares quite often & was disappointed with the "hookup" ratio initially. If you get the square wire cage with the leg snares, they will work a lot better if you cut the cage down by half & move the swivel to the side. It's difficult to describe but if you or anyone else wants to see pics you can pm me your email & I'll send a few your way. The "crabhawk" style folding traps work better but are more expensive & take a heavier rod/reel/line combo. They are also more prone to getting stuck in the rocks if there are any present. I've also been experimenting with making some homemade snares with modest success. As to the legality of using a snare & fishing at the same time its perfectly legal. The regs state that each crabber is allowed " crab may be taken by crab rings, pots, or baited lines ( limited to 3 rings, pots, or baited lines per person), by hand, dip net or rake. So they are considered separate from fishing. hope that helps you out
