Been trolling Bandit300's on Hamilton at a variety of speeds, anywhere from 1.5 to 3 mph. Mostly catching both black and white bass and hybrids and only a few crappie. To my best estimation, a Bandit300 at 1-1.5mph should run about 8ft. deep. At 2-3mph they will run as deep as 12ft. deep. A few times I've gotten busy in the boat and the speed topped 3mph. When this happens the bait begins to tumble and twist your line, get the hooks tangled, etc. A few times when running at 2.5 I ran across a point that was 11-12ft. deep according to my sonar and I could see the rods bouncing. When reeled in, the hooks had moss on them.
