10 Best Fish Finder For Pontoon Boat 2025 in the United States

The Lowrance Elite FS 9 Fish Finder is well-suited for use on a pontoon boat, offering a clear 9-inch multi-touch LCD screen that ensures good visibility and ease of use. The inclusion of the Active Imaging 3-in-1 sonar, which combines CHIRP, SideScan, and DownScan with FishReveal technology, provides detailed images of underwater structures and fish, enhancing your fishing experience. Additionally, it's ActiveTarget ready, enabling high-resolution live images of fish, which is a significant plus for serious anglers.

The preloaded C-MAP Contour+ charts provide high-resolution details of key fishing areas, making navigation and fish location more precise. This model supports full networking, allowing for integration with other devices and sharing of data such as sonar readings and waypoints, which widens its functionality and utility on a pontoon boat setup. However, to utilize the Active Imaging HD features, an additional S3100 module is required, which adds to the cost.

The unit operates on a 12 Volt DC power source, typical for marine electronics, and its sturdy construction ensures durability. While the cost may rise with the need for additional modules, for those looking for a comprehensive, high-tech fish finding system, the Lowrance Elite FS 9 is a strong contender.

The Humminbird XPLORE 9 GPS Fish Finder is a well-equipped device ideal for pontoon boat enthusiasts. Its 9-inch full HD touchscreen display offers high visibility and easy operation, with both touch and keypad controls. This makes it user-friendly, even in varying light conditions. The standout feature is the MEGA Side Imaging+ and MEGA Down Imaging+ sonar technologies, providing 200-foot range on either side and below the boat. This gives anglers a detailed view of their underwater environment and helps in identifying fish more effectively.

The Dual Spectrum CHIRP sonar adds to its ability to detect fish with precision, offering both wide and narrow modes for different fishing scenarios. The built-in GPS with Humminbird Basemap covers over 10,000 lakes, and it also includes LakeMaster and CoastMaster VX map cards for detailed navigation in both the U.S. and Canada. The AutoChart Live feature is particularly beneficial for creating real-time maps of your fishing spots, which can be saved on AutoChart Zero Line SD cards for virtually limitless mapping.

On the connectivity front, the fish finder is equipped with high-speed Ethernet and Bluetooth, making it compatible with NMEA 2000 networks and allowing for integration with other marine electronics like Minn Kota and Cannon products. This enhances the fishing experience by unlocking additional features. However, the unit is on the heavier side at 9 pounds, which might be a consideration if portability is important. Additionally, its premium features come at a higher price point, which may not suit all budgets. Despite these minor drawbacks, the Humminbird XPLORE 9 offers advanced sonar, comprehensive mapping, and robust connectivity, making it a top choice for serious anglers using a pontoon boat.

The Garmin Striker Vivid 4cv is an easy-to-use fishfinder suitable for pontoon boats with its compact 4-inch color display. The display, although on the smaller side, offers vivid scanning sonar color palettes that make it easier to distinguish between fish and underwater structures. This can be particularly useful for both novice and experienced anglers. The included GT20 transducer provides both traditional CHIRP sonar and CHIRP ClearVü scanning sonar, giving you a clearer and broader view of what’s beneath your boat. This helps in identifying fish and underwater obstacles more precisely.

Additionally, the high-sensitivity GPS allows you to mark waypoints, create routes, and track your boat's speed, which is excellent for navigation and ensuring you can return to promising fishing spots. The built-in Quickdraw Contours mapping feature lets you create personalized fishing maps, adding further value. One notable drawback is the relatively small 4-inch screen, which might be less convenient for those preferring larger displays, especially in wide-open water conditions. The device is button-operated, which could be less intuitive compared to touchscreen models. However, this may also mean greater durability and ease of use in wet conditions.

It includes a tilt/swivel mount for flexible installation, and at 2 pounds, it's quite portable. Connectivity is a plus with Wi-Fi capabilities, but it lacks more advanced networking features found in higher-end models. This fish finder is battery-powered, which offers flexibility but may require carrying spare batteries for longer trips. In summary, the Garmin Striker Vivid 4cv is a solid choice for pontoon boat owners seeking a reliable fish finder with clear sonar imaging and basic GPS functions, provided you don’t mind the smaller screen size.
