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

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 Lowrance Eagle Eye 9" Live Sonar is a robust and versatile tool designed to enhance your fishing experience on a pontoon boat. One of the standout features is its ability to offer four sonar views from a single transducer without needing additional modules. This includes Live Forward and Live Down views, which can significantly improve your ability to locate fish. The autotuning capability is user-friendly, allowing for focused imaging that adjusts automatically to provide optimal clarity, making it easier for both seasoned anglers and novices alike.

The detailed C-MAP charts with Genesis Live add another layer of sophistication, enabling you to navigate effectively and spot underwater structures that attract fish. The 9-inch IPS display is another highlight; it ensures great visibility from various angles, even in bright sunlight or when wearing polarized sunglasses.

However, it comes with some drawbacks. While the twist-lock connector system simplifies installation, beginners may still find it a bit challenging compared to more plug-and-play options. Additionally, its weight of around 2 pounds might be considered on the heavier side for some users, especially if they plan to move it between different boats or kayaks regularly. The display quality is excellent, but those looking for the sharpest resolution might find it lacking compared to higher-end models. In terms of connectivity, it lacks advanced networking features that some fishing enthusiasts may desire, such as smartphone integration or Wi-Fi capabilities. Despite this, its solid build and effective sonar functionalities make it a strong contender for pontoon boat users who want reliable performance without the complexity of high-end models.

The Garmin Striker Vivid 7sv is a solid choice for anyone using a pontoon boat who wants a reliable and easy-to-use fishfinder. It features a clear 7-inch color screen with vivid scanning sonar color palettes, which makes spotting fish and underwater structures easier than on some older or black-and-white models. It supports several sonar types—including Garmin’s CHIRP traditional sonar and ClearVü and SideVü scanning sonars—giving you detailed views beneath and around your boat, although you’ll need the compatible transducer included for all features to work.

The built-in high-sensitivity GPS lets you mark fishing spots, create routes, and even check your boat’s speed, which is handy for navigating lakes and rivers. The Quickdraw Contours mapping feature is a nice bonus, allowing you to generate custom depth maps as you go, which can be very helpful for understanding your fishing area better.

Connectivity-wise, the fishfinder can connect via Wi-Fi to Garmin’s ActiveCaptain app on your smartphone. This allows easy transfer of waypoints, smart notifications, and software updates without needing to connect to a computer. The device is also compact and lightweight, with a tilt/swivel mount included for flexible positioning on your pontoon. While the display is large enough for clear viewing, it may not be as crisp as some higher-end models with larger or higher resolution screens. Also, the interface uses buttons rather than a touchscreen, which some users might find less intuitive. For those looking for an effective fishfinder for a pontoon boat that balances good sonar capabilities, GPS mapping, and wireless connectivity without overwhelming complexity, the Garmin Striker Vivid 7sv presents a compelling option.
