I am sure you can get better info from the more experienced than from a part timer like me but here goes. I used to have downriggers but seemed like to much work and did not produce that well. Most use jet divers but I like Dipsy divers, for me their are easier to use and adjust. I only run 4 rods and the dipsy's work well for me. Tried the planner board thing but again seems like to much work for me as I get onto perch to soon to make the time and trouble worthwhile. As far as perch hotspots you have to watch as they can be anywhere, I have caught them all over the western basin on any given day. Normally not in the same spot as the day before so searching is the key. I just enjoy being on the water whether I am catching or not so simpler is better for me and we prefer the perch, not that walleye is bad hell no we eat as many as we can, just prefer the perch.
