HI-LO Rig:
Tie a barrel swivel on the leader material. Tie a dropper loop about 12 inches below the swivel. Tie another dropper about 12-18 inches below the first one. Tie a snap swivel about 12-18 inches below the bottom dropper. Put your hooks of choice on the droppers. Put the weight on the snap swivel. I use palomer knots at both swivels and to connect to the main line.......
You can substitute 3-way swivels for the droppers, but I don't like that - more knots, more tackle, etc.......means more points of failure......
You can do the same thing using only one dropper and one hook. I like the two, as you can put two different types of bait on, or two of the same bait.......if one is gone due to crabs or, better yet, missed hits, they can always come back for dessert.....
