If your not going to use boards, use 6 oz bouncers in the front rod holders, 4 oz in the middle holders and if you have another on board use 2 oz in the back holders. That way you won't get any tangles. If only 2 of you, use 4oz and 2 oz bouncers if that's all you have. It doesn’t matter if you make/buy yours from 1 ft long to 5 ft long. The weighting system is what’s going to determine your depth along with your speed. Taking speed out of the picture for now. Get your boat set at let's say 1.2 mph to start with. Put out a harness on the heaviest bouncer. Let out line on your line counter reel with your thumb lightly on the spool till you touch bottom. Right there your harness would be running approximately 4 to 5 ft off the bottom once the bouncer reaches the boats speed/water drag against your line etc. Let out line and touch bottom again, your harness would be 3ft off bottom. Touch again and your lure will be running just off bottom if not tagging the high spots on the bottom. Do that with each bouncer and you know where your running. And can repeat.
