10 Best Side Imaging Fish Finders 2026 in the United States

The Humminbird XPLORE 10 GPS Fish Finder is a solid choice for anglers wanting a clear and detailed view underwater thanks to its 10-inch HD touchscreen with 1280 x 720 resolution. Its MEGA Side Imaging+ sonar covers up to 200 feet on each side, providing sharp images to help spot fish and understand underwater structures better than many basic models. The unit’s Dual Spectrum CHIRP sonar gives flexible options for detecting fish in different water conditions.

For navigation, it includes built-in GPS with detailed maps covering over 10,000 lakes plus additional US and Canada charts, which is great for planning trips and marking fishing spots. The AutoChart Live feature lets you create your own depth and vegetation maps while on the water, adding extra value for serious anglers. Connectivity is another strong point, with high-speed Ethernet and Bluetooth allowing you to connect to other devices like trolling motors or networked fish finders, plus compatibility with NMEA 2000 systems. The transom mount transducer comes included, making setup easier.

This unit requires a corded power source, which means it needs installation on a boat with power access, limiting portability. While it is not the cheapest option, its powerful sonar, large clear display, and advanced mapping features make it well-suited for fishing enthusiasts who want detailed underwater imaging and sophisticated navigation tools without overly complex tech. Beginners might need some time to get used to all features, but the dual control system (touchscreen plus keypad) helps with ease of use.

The Garmin ECHOMAP UHD2 94sv is an impressive option for side-imaging fish finders, especially for anglers seeking clarity and ease of use. Its 9-inch touchscreen is bright and easy to read, even in sunlight, which is a significant advantage during outdoor fishing trips. The included GT56-TM transducer offers excellent traditional, ClearVü, and SideVü scanning capabilities, allowing you to see underwater structures and fish with great detail, enhancing your fishing strategy.

One of the standout features is the built-in Garmin Navionics+ coastal charts, which provide detailed mapping that can guide you to the best fishing spots. The device also offers built-in Wi-Fi connectivity, allowing you to share sonar data, waypoints, and routes with other ECHOMAP UHD2 units wirelessly. This is particularly useful if you're fishing with a partner or need to coordinate with others on the water.

While the ECHOMAP UHD2 is packed with great features, it might have a bit of a learning curve for those who are not tech-savvy. Some users may find the multitude of options slightly overwhelming at first. Additionally, while the touchscreen is responsive, using it with wet hands or in the rain could be a challenge, which is something to keep in mind in tougher weather conditions. In terms of power output and frequency, it performs well within its category, though it’s always good to check if it meets your specific fishing needs. The choice of mounting, whether dashboard or flush, adds versatility but may require some additional tools for installation.

For recreational boaters and serious anglers alike, the Garmin ECHOMAP UHD2 94sv provides an excellent combination of functionality and advanced features, establishing it as a strong contender in the side-imaging fish finder market.

The Lowrance Elite FS 7 Fish Finder stands out with its 7-inch high-resolution, multi-touch screen, making it easy to view and use. The screen size is quite suitable for most users, providing a clear view while still being compact. The Active Imaging 3-in-1 sonar is a major strength, offering CHIRP, SideScan, and DownScan capabilities, which helps in identifying fish and underwater structures with refined detail.

The inclusion of preloaded C-MAP Contour+ charts adds value by providing detailed mapping of 8,900 U.S. lakes, which is useful for identifying key fishing spots and navigating accurately. GPS integration is another plus, helping users mark waypoints and navigate efficiently on the water. The fish finder is also ActiveTarget ready, meaning it supports high-resolution live sonar images, which can be very beneficial for serious anglers wanting real-time data on fish movements.

Connectivity options are robust with integrated wireless, NMEA 2000, and Ethernet, allowing for the addition of extra devices like radar or sharing data between displays, enhancing the fishing system. However, the maximum measuring depth of 40 feet might be limiting for users fishing in deeper waters. Additionally, the product's weight at over 9 pounds could be considered heavy for a portable device. Despite these drawbacks, the Lowrance Elite FS 7 is a solid choice for both casual and serious anglers, offering a comprehensive set of features to improve the fishing experience.
