Side imaging remains one of the most effective tools for targeting walleye—especially when fishing shallow flats in summer. In this video, walleye stick Tom Boley shares a proven method for using side imaging to locate and catch more walleye without relying on forward-facing sonar. This strategy is straightforward, fast-paced, and ideal for anglers who want to cover water efficiently while making precise presentations.

Why Side Imaging Still Dominates
While forward-facing sonar has become popular, side imaging still offers a major advantage when scanning wide areas of water quickly. By projecting a clear image of the lake bottom and surrounding structure to both sides of the boat, side imaging allows anglers to spot fish schools, bait clusters, and transition zones with precision. This is especially valuable when targeting walleye that roam weed edges, sand flats, and breaks during the mid- to late-summer season.
The Importance of Range Settings and Screen Layout
Maximizing side imaging starts with the right screen setup and range configuration. Many anglers prefer to run their side imaging out to 90 or even 100 feet on each side. Including range lines and interval markers on the display makes it easier to estimate distance and cast accurately once fish appear. Using a split screen with mapping and imaging also helps anglers track boat position while scanning for fish.
Reacting to Fish in Real Time
Once fish show up on screen, timing becomes everything. The key is to respond quickly with an accurate cast to the zone where fish are marked. By maintaining a consistent casting distance and having gear prepped ahead of time, anglers can make immediate presentations without delay. The faster the reaction time, the better the chances are of triggering a strike. This real-time targeting is what makes side imaging so effective.
