10 Best Side Imaging Fish Finders 2025 in the United States

The Humminbird XPLORE 12 GPS Fish Finder is a strong choice for anglers looking for detailed side-imaging and navigation capabilities. Its 12-inch HD touchscreen offers clear visuals with a 1280 x 720 resolution, making it easier to spot fish and underwater details. The standout feature is the MEGA Side Imaging+ sonar, which provides wide 200-foot scans on each side, delivering highly detailed underwater views. The Dual Spectrum CHIRP sonar further enhances fish detection with both wide and narrow beam options, helping you find fish more effectively.

GPS integration is solid, featuring built-in maps with coverage of over 10,000 lakes and compatibility with popular mapping cards like LakeMaster, CoastMaster VX, and Navionics. The AutoChart Live feature allows you to create custom maps in real time, which is a big plus for exploring new waters. Connectivity options include Ethernet, Bluetooth, and NMEA 2000 compatibility, allowing smooth integration with other marine devices like Minn Kota motors. The package includes a quality transducer and offers dual control options (touchscreen and keypad), which adds flexibility depending on your preference or weather conditions.

One downside is that it’s battery powered, which might limit usage time compared to models with external power sources. While it has good power and imaging range, some users might find the price a bit high, especially if they don’t need advanced mapping features. The fish finder is well suited for serious hobbyists and semi-professionals who want detailed imaging and reliable GPS navigation, but casual anglers might find simpler models more cost-effective. This product effectively balances advanced sonar technology with user-friendly operation, making it a capable tool for freshwater and coastal fishing.

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.
