I've managed to put together a setup that gets crankbaits down really deep. First I use a 7'3" G-Loomis MH Deep Flex Crankbait Rod with 12lb Seaguar Flourocarbon and a Revo Winch. The 12lb flouro makes sure that line sinks and gets that bait down a foot or so deeper than normal. The rod allows you to cast super far to again get maximum depth and the reel allows to crank very very slowly since its 5.4:1 which keeps the bait from rising too fast. This combo will let you get those deep divers down deep like you want. You can expect true depth out of your DD-22's and others.
