10 Best Sonar Fish Finders 2025 in the United States

The Lowrance Elite FS 9 Fish Finder is a robust tool designed for avid anglers looking for detailed underwater views and efficient fishing functionalities. With its 9-inch high-resolution LCD touchscreen, users will find it easy to operate and read, even in bright conditions. The large screen size ensures that details are clear, making your fishing experience more productive.

The Active Imaging 3-in-1 transducer, which includes CHIRP, SideScan, and DownScan, provides detailed imaging of structures and fish, improving your chances of a successful catch. The FishReveal feature further enhances clarity by highlighting fish on the display. For those who prefer live updates, this fish finder is ActiveTarget ready, allowing you to see high-resolution images of fish in real-time.

GPS integration with preloaded C-MAP Contour+ charts helps in precisely locating fish-holding areas and navigating through 8,900 U.S. lakes with detailed 1-foot contours. The device supports full networking, with wireless, NMEA 2000, and Ethernet connectivity, enabling you to build an integrated fishing system with additional accessories. This device may not be the most portable due to its larger size and 12-volt power requirement, making it more suitable for boat installation rather than for portable use. The Lowrance Elite FS 9 is a highly capable fish finder for those who are serious about fishing, offering excellent imaging and comprehensive GPS features, though it may not be as convenient for those needing a more portable solution.

The Garmin Striker Vivid 7cv is a user-friendly fishfinder that comes with a 7-inch color display, making it easy to read and use while out on the water. One of its standout features is the vivid scanning sonar color palettes, which help distinguish between fish and underwater structures more clearly. This model includes the GT20 transducer, providing both CHIRP traditional sonar and CHIRP ClearVü scanning sonar, offering detailed and accurate readings of what’s below the surface.

The addition of high-sensitivity GPS allows you to mark waypoints, create routes, and monitor your boat’s speed, which is highly useful for navigation and returning to productive fishing spots. Another significant benefit is the built-in Quickdraw Contours mapping feature, enabling you to create your own fishing maps on the fly. The device also supports Wi-Fi connectivity, allowing you to connect with the ActiveCaptain app on your smartphone to transfer waypoints, receive notifications, and access the Garmin Quickdraw Community for shared data and maps.

However, there are a few considerations to keep in mind. The device relies on button controls, which might feel less intuitive compared to touchscreens. Additionally, while the 7-inch screen is a good size for visibility, it may not be sufficient for those who prefer larger displays. The unit’s portability could be a concern for some users, as it weighs 4.4 pounds and requires a surface mount, which might not be ideal for smaller boats or those needing more flexible installation options. Despite these points, the Garmin Striker Vivid 7cv offers a comprehensive set of features that make it a solid choice for both novice and experienced anglers looking for reliable fishfinding and navigation tools.

The Lowrance Eagle Eye™ 9 Live + C-MAP® is a solid choice for anglers looking for a reliable and high-performing sonar fish finder. With its 9-inch IPS screen, the display offers excellent visibility from all angles, even when wearing polarized glasses. The autotuning live sonar feature is particularly beneficial, providing focused down and forward views without the need for additional modules, which simplifies setup and usage.

Additionally, the included C-MAP® Discover charts for the US and Canada enhance navigation and fishing accuracy, making it a valuable tool for both seasoned and amateur fishermen. The twist-lock connector system is another strength, ensuring easy installation on various boats and kayaks, thus adding to its portability and versatility.

For those prioritizing GPS integration, detailed sonar views, and durability, this fish finder stands out as a strong contender in its category. However, it's important to note that the device is battery-powered, which might require frequent recharging depending on usage.
