Chasin's response is almost dead on of what I am doing with my downriggers. I use the small slide diver to gain both depth and width of my trolling pattern. You run a lead behind your small slide diver, lets say 10 pulls or arm lengths of line, you then let out the slide diver (I use 50 feet or so), hook your line to the downrigger ball (I use rubber bands), then let the ball down. By doing this, you are getting away from the ball and open up your trolling pattern at depth. A lot of people us SWR's, or lead core on their riggers. This does the same thing, but also gets wider and you can control how far below the ball you are. -Eric, Owner of Slide Diver
