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

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 010-01550-00 Striker 4 is a compact and user-friendly fish finder designed for pontoon boats. It features a 3.5-inch display with a resolution of 480 x 320 pixels, providing clear and detailed images of what’s beneath your boat. The Chirp Sonar technology enhances target separation and provides crisp fish arches, making it easier to identify fish and underwater structures. The Clear Vu scanning sonar offers near-photographic images, giving you a comprehensive view of the water around your boat.

The device also includes a built-in GPS for marking waypoints and navigating to specific locations, which is particularly useful for returning to productive fishing spots. Installation is straightforward, and the interface with dedicated buttons is simple to use, even for beginners. The unit is waterproof with an IPX7 rating, meaning it can withstand accidental water exposure.

However, the 3.5-inch display might be considered small for some users, especially when compared to larger models available in the market. Additionally, while the sonar is effective in both freshwater and saltwater, it may not offer the same depth range in saltwater (up to 750 feet) as it does in freshwater (up to 1,600 feet). Connectivity options are limited, as it does not support networking with other devices. Despite these minor drawbacks, the Garmin Striker 4 offers excellent value for its price, making it a great choice for amateur and hobbyist anglers who need a reliable and portable fish finder.

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.
