Thank you. When I was shopping for trolling rods before, I saw planer board, dipsy diver, lead core, and downrigger all as options for a type of rod. For longlining is there a certain type that would be better than others or a kind I should stay away from?
Sorry for the late response, haven't been on here much. But to start I would keep it basic. Get some trolling rods. Start with a couple shorts, 5'6" and a couple 8'6". Add lead core if you want, the thing that drives me nuts with lead core, is you are tied to a specific speed of 2.0mph or slower. Much faster and the line rises due to its thickness. more on this in a minute. No need for down riggers fishing for walleye in this state. Yes, they can catch fish, but not often you will be pulling cranks over 40 fow, and you can get that deep with lead core or snap weights. I personally don't like dipsy divers but to keep things simple to start, I would stay away from them and add them later if you want.
Ok lead core: I will probably catch some flack for this, but I think it's completely over rated. I use it, I catch fish with it, but there isn't anything lead core can do that my snap weights can't. and when I want to get down deep, say 30 feed deep, with lead core I need to let out 150' feet of line. I can get that deep running 70-80 feet of total line out with a 3oz snap weight, plus I late in summer when the fish are super active with warm water, I can run at 2.5mph and 3.0mph and stay down deep, which lead core can't do. Don't get me wrong, I like lead core, it works, but I find myself using snap weights much more.
Also, late summer and fall, don't be afraid to put on big cranks and troll deep. Nothing like having a 25"+ pound a crank zipping by at 2.5mph with a big lip on the front.
