10 Best Kayak Fish Finders 2025 in the United States

The Lowrance Elite FS 9 Fish Finder is designed for anglers who want detailed underwater insights. It features a 9-inch high-resolution multi-touch LCD screen, making it easy to view and navigate through various settings. One of its standout features is the Active Imaging 3-in-1 transducer, which combines CHIRP, SideScan, and DownScan sonar technologies. This allows for clear and refined imaging of underwater structures and fish. Additionally, it supports ActiveTarget Live Sonar, which provides real-time images of fish and their movements, enhancing the fishing experience.

The preloaded C-MAP Contour+ charts are another significant advantage, providing detailed mapping of 8,900 U.S. lakes to help locate prime fishing spots. The inclusion of full networking capabilities like integrated wireless, NMEA 2000, and Ethernet connectivity allows for easy integration with other devices and data sharing. However, the device is relatively heavy at 4.53 kilograms, which might affect portability for some users, especially those looking for a lightweight option to carry on a kayak.

The high-tech features and networking options might be overwhelming for beginners who prefer simpler fish finders. Additionally, it requires a 12 Volt DC power source, which is something to consider for long fishing trips. The Lowrance Elite FS 9 is a robust and feature-rich fish finder suitable for serious anglers who need advanced sonar capabilities and detailed mapping, but its weight and complexity might be a drawback for casual users or those prioritizing portability.

The Lowrance Elite FS 7 Fish Finder is a solid choice for kayak fishing, offering several features that enhance fishing experiences. The 7-inch high-resolution, multi-touch LCD screen is a good size for visibility in a kayak, making it easy to interpret sonar data and navigate. The Active Imaging 3-in-1 transducer is a standout feature, combining CHIRP, SideScan, and DownScan sonar technologies, which provide a detailed view of underwater structures and fish. Additionally, the FishReveal feature is useful for detecting fish around these structures, increasing the chances of a successful catch.

Another strong point is the preloaded C-MAP Contour+ charts, offering precise navigation and detailed maps of 8,900 U.S. lakes, which is valuable for planning fishing trips and locating fish-holding areas. The unit is also ready for ActiveTarget Live Sonar, allowing users to see real-time images of fish and their responses to lures. Full networking capabilities, including wireless, NMEA 2000, and Ethernet, allow for integration with other marine electronics, which can be beneficial for those using more advanced setups.

The power output (12 Volt DC) and the maximum measuring depth of 40 feet might limit its use in deeper waters. Portability might be a concern due to its weight (9.31 pounds) and the need for mounting in a kayak, which could be cumbersome for some users. Despite these points, the Lowrance Elite FS 7 remains a powerful tool for those looking to enhance their kayak fishing experience, thanks to its advanced sonar features, detailed mapping, and comprehensive networking capabilities.

The Garmin Striker Vivid 7sv is designed to be a user-friendly fishfinder with a bright 7-inch color display that makes it easy to see fish and underwater structures. Its vivid scanning sonar color palettes help differentiate fish from other objects, which is a big plus when you're on the water. It supports multiple sonar types including traditional CHIRP, ClearVü, and SideVü, giving you detailed views beneath and beside your kayak. The built-in high-sensitivity GPS lets you mark waypoints and create routes, which is great for tracking your favorite fishing spots or navigating unfamiliar waters.

The unit also includes Quickdraw Contours mapping, allowing you to create custom depth maps as you fish. Wi-Fi connectivity is a modern bonus, letting you connect to a smartphone app to transfer waypoints and receive updates without hassle. On the downside, the unit relies on button controls instead of a touchscreen, which might feel a bit dated for some users. While it includes a transducer suitable for kayaks, the device is somewhat larger and heavier than ultra-compact models, so consider your portability needs if you prefer very lightweight gear.

The Striker Vivid 7sv is a solid choice for kayak anglers who want clear sonar images, GPS functionality, and smartphone integration, all without a steep learning curve.
