This is a method that can be extremely effective if you figure out the right formula.
It all starts by locating fish and finding your target depth range.
Once you have a good idea of what depth range you will want your bait at, you will be able to pick out a few different crankbaits to use.
If you have multiple anglers in the boat try to select different colors and body styles of crankbaits. This will help you determine what features on the bait the fish are keying in on.
Another thing we will do is switch out our baits often. Play around with the size and color of crankbaits. A small change can make a huge difference in the number of bites.
Once you have your crankbaits selecting that is when your Off Shore Planer boards come into play.
Trolling with boards allows you to cover more ground and spread your baits out further.
One recommendation when trolling for deepwater walleyes with boards is to use a line counter reel. By using a line counter reel you will know exactly how far back your bait is and how far away your board is from the boat. It also makes it easier to replicate the process.
The key to deepwater trolling for walleyes is to your formula dialed in and then continue to repeat the process.
