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 Ultra 2 is a solid choice for anglers looking for a high-quality side-imaging fish finder. With a large 12-inch screen, it offers an impressive resolution that makes it easy to see underwater details, even in bright sunlight, which is a real plus for those spending long hours on the water. The device is equipped with Garmin Navionics Plus mapping, providing comprehensive coverage of US and Coastal Canada waters, which can be incredibly useful for navigation and finding fishing spots. Additionally, the LiveScope live-scanning sonar feature allows for real-time monitoring of fish movements, making it easier to locate and catch fish.

Some users might find the lack of a transducer included in the package a drawback; this means additional costs for those looking to maximize the device's potential. The power source is battery-operated, which may raise concerns about battery life during extended trips, especially if using features like LiveScope that demand more power. While the weight of 5.5 pounds makes it relatively portable, it may still be cumbersome to manage for some users, particularly when mounting it or moving it aboard a smaller vessel.

Connectivity options are not explicitly mentioned, so users who rely heavily on syncing their devices may need to check for additional compatibility. The Garmin ECHOMAP Ultra 2 is well-suited for serious anglers who value advanced features and high performance in a fish finder, but it may require extra investments and considerations for those just starting out.
