I will put you on these big fish, explain a couple of techniques and give you some hints on how to catch them. It s not the only method, but it is definitely the most effective. The next best way is to troll with snap weights and planner boards. Planner boards and lead core line give your baits more action from the surface. Snap weights do just the opposite, they reduce the action from the surface.
Snap weights absorb a lot of the wave action, while lead core transmits it to the lure.
Trolling over deep water is one of the most effective methods of producing big walleyes. Contrary to what most people believe, trolling has to be very exact if you are going to be effective. Where you make your trolling pass is only a small part of the total presentation. Things like water temperature, water depth, lure depth, lure color, lure size, lure action, speed of presentation, direction of presentation, wind, wind direction, and surrounding structure all plat an important role in how effective trolling will be for you. It is what controls the depth that these fish are in, where most of the oxygen is and where the food is.
