Hey Mike I'm in the central basin too. Used to fish for perch a lot. Going to try trolling for walleye. The 10 perch bag limit is ridiculous. Thanks for the good info will be checking in for more tips.

Speed is very critical with any presentation that uses a weight to achieve depth. Divers are not as speed sensitive. With that, I think the best way to start is put on weight desired and with rod in hand set out enough line to get to drag bottom, note depth. Use this as a start.
