Andrew Martinsen's Walleye Fishing Update Speed Trolling Map Success Utilizing Topo Maps and Speed Trolling to Pull in More Walleye An advanced speed trolling technique involves the use of a topographic map and a depth finder. Troll over areas where there is underwater structure shown on the map, using the fish finder and the depth finder to locate where the Walleye are and what depth they are staying at. Many anglers troll in an S pattern, but trolling a contour line may be a better option on certain days and in certain waters. Troll the contour of the shore, staying out far enough to be over deeper water, and moving from one structure to the next. Troll in a back and forth motion along the contour, varying the speed from two or two and a half miles an hour all the way up to four or five miles an hour. Pay attention to what is working. If varying the speed of your trolling does not work, try to switch to a live bait harness or a jig, so that you can use the speed of the trolling to bump the lure up and down on the bottom of the water column. Using a bottom bouncer or spoon when trolling along at higher speeds may be effective, but many times these lures will not stay at the depth you want them to be if your trolling speed is high. Do not be wary of trying new techniques, or switching up tactics at any time. Speed trolling can catch you more walleye. But make certain to always keep safety in the front of your mind. If something seems like too great of a risk out there, it likely is. Staying safe should be priority number one always. Have fun on the water, and stay safe!
