Here's what you use:
You have a bobber (needs to be of decent size) then you string your line through the bobber or around it, depending on what sort of bobber/float you have. Then, you tie on a 1 oz banana weight right below the bobber to the top part of the weight, then on the other side of the weight you tie on a few feet of leader and then your hooks. That's what I do when fishing for silvers, but I'm not positive on the leader length for saltwater Chums...
