I agree with all of above posts. I always use a depth finder to locate structure. I also troll, using a rod holder, using deep diving crankbaits, usually Rapalas or Reef Runners. I have also used large, heavy swimbaits, and they work great. When I find fish, I will stop and switch to a jig with gulp or powerbait, casting toward the structure that holds fish. Vary the retrieve, popping the jig up, and keeping a tight line on the drop. It is usually the drop that will trigger the bite. I also, sometimes allow the bait to sit on the bottom for 20-30 seconds, remaining motionless, which often triggers a strike, if the fish are not aggressive.

I also don't take or use Lindy Rigs, since I don't take live bait. I use three jig sizes, 1/8, 1/4, and 3/8 oz. I choose the size according to the depth and wind. You want the lightest one that will get to the bottom and give you control of the jig. This post doubles as my tip of the month. :D
