10 Best Fish Finder For Trolling Motor 2025 in the United States

The Garmin ECHOMAP UHD2 94sv is a solid choice for those looking to enhance their trolling motor fishing experience. Its 9-inch touchscreen display is bright and easy to read even in sunlight, which is great for long days on the water. The included GT56 transducer supports multiple sonar types like traditional, ClearVü, and SideVü, providing detailed underwater images and fish targeting, which can significantly improve your fishing efficiency.

The built-in Garmin Navionics+ coastal charts and integrated Navionics data are ideal for navigation and ensuring you stay on course. It is also compatible with other ECHOMAP UHD2 units via Wi-Fi for sharing sonar, waypoints, and routes, adding convenience if you have multiple devices on your boat.

Another standout feature is its ability to wirelessly connect to the Force trolling motor, allowing you to create and follow routes, navigate to waypoints, control speed, and monitor battery life directly from the chartplotter. This integration can simplify your fishing trips and give you more control over your boat's movements. However, this fish finder comes with a relatively high price tag, and its advanced features might be overwhelming for beginners. Additionally, some users might find the 1024 x 600 resolution to be lower than expected for such a large display, although it is still clear and detailed. If you are an experienced angler looking for a feature-rich, easy-to-use fish finder that integrates well with a trolling motor, the Garmin ECHOMAP UHD2 94sv is worth considering.

The Lowrance Elite FS 9 Fish Finder is a solid choice for anglers using trolling motors, offering a mix of advanced sonar features and user-friendly design. One of its standout features is the Active Imaging 3-in-1 sonar technology, which includes CHIRP, SideScan, and DownScan capabilities with FishReveal, providing a high level of detail and accuracy in identifying fish and underwater structures. This is beneficial for serious anglers seeking precise information on underwater environments. Additionally, the device is ActiveTarget ready, allowing for live sonar imaging, which is excellent for real-time observation of fish behavior, although this requires purchasing additional accessories.

The 9-inch multi-touch LCD display is both sizable and high-resolution, making it easy to view and interact with the device, even in harsh sunlight. It’s also designed for easy installation and use, which is ideal for users who may not be familiar with complex electronics. The inclusion of preloaded C-MAP Contour+ charts offers detailed mapping of over 8,900 U.S. lakes, enhancing navigation and fishing spot identification. However, some users might find the price point a bit high, especially considering that full functionality may require additional purchases like the ActiveTarget sonar.

Though the device supports extensive networking capabilities, integrating it with other systems might be complex for beginners. The Lowrance Elite FS 9 Fish Finder is well-suited for dedicated anglers looking for an advanced, feature-rich fish finder for their trolling motor, though it may be overkill for casual users or those on a budget.

The Lowrance Elite FS 7 is a solid choice for anglers using a trolling motor who want detailed underwater imaging and reliable navigation. It features an Active Imaging 3-in-1 sonar that combines CHIRP, SideScan, and DownScan technologies, offering clear views of fish and structures around your boat. This makes it easier to spot fish and underwater features with greater detail than basic fish finders. The 7-inch touchscreen display is bright, responsive, and user-friendly, helping you operate it smoothly even on the water.

It comes preloaded with C-MAP Contour+ charts, providing highly detailed 1-foot contours for more than 8,900 U.S. lakes, so you can pinpoint fishing hotspots and navigate confidently. Another benefit is its full networking support, which allows you to connect with other Lowrance devices and share data such as sonar and waypoints. The unit runs on 12V power, typical for boat setups, and supports ActiveTarget Live Sonar if you choose to expand, giving real-time views of fish movement near your lure.

On the downside, its maximum depth range is about 40 feet, which might be limiting if you fish in deeper waters. Also, the installation includes several accessories but may feel a bit bulky with a nearly 9.3-pound weight, which could matter in small boats. For someone focused on trolling motor use who values clear imaging, easy touchscreen controls, and detailed lake maps, this model offers a good balance of powerful sonar and GPS features without overwhelming complexity.
