Forward-facing sonar has changed how bass anglers locate fish, watch their movements and present lures. But having a clearer underwater picture does not automatically mean catching more fish. Two fisheries studies published in 2026 reached different results, revealing that the technology’s effectiveness depends on habitat, water depth and how anglers use their time.

For recreational fishermen and tournament competitors, the findings challenge a common assumption: expensive electronics do not automatically produce better fishing results. In some situations, live-imaging sonar can improve catch rates. In others, anglers may spend so much time tracking individual fish that they actually reduce their opportunities to catch them.

A 2026 Tournament Study Found That Habitat Matters

A study published in the North American Journal of Fisheries Management examined forward-facing sonar use across eight Major League Fishing Bass Pro Tour events during 2025.

Researchers Ryan Gary, Joseph Love and Steven Bardin analyzed information from 73 professional anglers. Tournament rules restricted live-imaging sonar use to one of three daily competition periods, allowing researchers to compare performance during periods of use and nonuse.

The multi-fishery live-imaging sonar research paper found that catch-rate improvements varied considerably between fisheries.

Lake Conroe in Texas and Lake Murray in South Carolina showed notable increases during sonar-use periods. However, researchers found no statistically significant catch-rate advantage on the Potomac River or Lake Guntersville.

Another important finding was that anglers did not catch significantly heavier bass when using live-imaging sonar.

The research also identified a relationship between sonar use and underwater habitat. Anglers were more likely to use the technology when targeting bass in deeper water and areas with less complicated cover. Maryland DNR’s research summary reported that anglers catching fish deeper than nine feet were nearly three times as likely to be using live-imaging sonar.

This suggests that forward-facing sonar has a particular advantage when bass are suspended or moving through relatively open water rather than hiding among shallow vegetation and shoreline cover.

Why Another Study Found Fewer Smallmouth Bass Caught

A separate experiment conducted by researchers working with the University of Wisconsin examined how forward-facing sonar affected smallmouth bass fishing on Nebish Lake in northern Wisconsin.

Unlike the professional tournament analysis, this research used a controlled experiment involving two teams of two anglers. The teams alternated access to forward-facing sonar during the summer of 2025.

Across 512 hours of fishing, researchers recorded 1,722 smallmouth bass.

The results were surprising. Catch rates were approximately 0.64 fish per hour lower when the experimental teams used forward-facing sonar. However, the average length of captured smallmouth increased by approximately 25 millimeters, or just under one inch.

The Wisconsin forward-facing sonar experiment published in Fisheries Research also identified changes in angler behavior.

When using the technology, anglers covered less distance, moved more slowly and made sharper turns. Their movements were consistent with spending additional time searching for individual fish rather than covering larger areas of the lake.

The researchers suggested that this additional searching could help explain why catch rates declined despite the slightly larger average fish.

This finding offers an important lesson for anglers: locating a fish on an electronics display and efficiently catching fish are two different skills.

Why the Two Research Results Are Not Contradictory

At first glance, one study showing higher catch rates and another showing lower catch rates might appear inconsistent. However, the experiments examined different fishing environments and conditions.

The professional tournament analysis included multiple fisheries, different habitat types and experienced competitors. The Wisconsin experiment concentrated on smallmouth bass in one northern lake with a small number of experimental anglers.

The difference in habitat is particularly important.

Deep reservoirs with relatively open underwater environments can provide opportunities for forward-facing sonar to locate suspended fish. In contrast, shallow lakes with vegetation, timber, docks and complicated shoreline cover offer different challenges.

Anglers fishing around thick vegetation may gain more from identifying productive cover, understanding depth changes and presenting lures accurately than from tracking individual fish on a screen.

The studies therefore suggest that sonar effectiveness should be evaluated according to the fishery rather than treated as a universal advantage.

How Bass Anglers Can Avoid Spending Too Much Time Watching Screens

The research offers practical lessons for anglers who already own forward-facing sonar or are considering investing in it.

Use electronics when they answer a specific fishing question.

If bass are suspended over deep water, live imaging can help locate individual targets and observe their responses to a lure. However, scanning an entire lake without a clear objective can consume valuable fishing time.

Continue covering productive water.

The Wisconsin experiment suggests that excessive searching can reduce the distance anglers travel and the opportunities they create through additional casts. Moving through productive areas and testing different presentations remain important skills.

Match technology to habitat.

Deep, open water and suspended fish provide situations where live imaging may offer a practical advantage. Shallow vegetation, docks, timber and complex shoreline cover may require more traditional approaches.

Measure actual fishing results.

Instead of judging a fishing session by the number of fish displayed on the screen, compare real catches, average fish size and time spent fishing. Recording results across similar conditions can help anglers determine whether the equipment is genuinely improving their performance.

Tournament Rules and Fish Care Still Matter

Forward-facing sonar has also become an important subject in tournament regulations. Different organizations and events can impose different restrictions, so competitors should never assume that equipment permitted in one tournament will automatically be allowed in another.

For example, Bass Lake Roadhouse’s Guntersville Elite Qualifier preparation guide explains how the event’s restriction on forward-facing sonar changes tournament preparation and increases the importance of traditional pattern-fishing skills.

There is also a conservation consideration. If technology increases the number of bass caught in particular habitats, anglers may need to pay closer attention to handling and release practices.

However, higher catch rates in a tournament analysis do not automatically establish that a fish population is declining. The studies examined angler catches and behavior, not long-term population collapse.

Fisheries managers will need to consider habitat, fishing pressure, species, seasonal patterns and fish survival when evaluating the broader consequences of advanced electronics.

The Future of Bass Fishing Is About Better Decisions

Forward-facing sonar is a valuable development, but the latest research shows that its usefulness depends on more than screen quality or equipment price.

One study found improved catch rates in certain fisheries, while another demonstrated that excessive searching could reduce smallmouth catch rates despite producing slightly larger fish.

For everyday anglers, the message is straightforward: use electronics to support fishing decisions rather than allowing the screen to control the entire day.

Understanding habitat, choosing productive presentations and knowing when to move remain essential parts of successful bass fishing, regardless of how advanced the equipment becomes.
