The boards you got are fine,boards just get your baits away from the boat the jets get your lures to depth. Get dive charts for your jets.I use lurk,and true trip jets and have done very well with both,but they have their own dive charts 99% of the captains on Erie around the islands use true true trips. You need a radio to listen to the depth range they are fishing so you need their charts to see how deep they are then convert that to what your using to achieve the same depth or close to that higher up its better than lower as walleye feed up.there are more variables, speed and line size. Line size isn't as important at say 50 back,maybe a foot. Do s turns to get speeds dailed in more, inside bite slow down,outside bite speed up. I hope this helps Frank
