10 Best Boat GPS Depth Finders 2025 in the United States

The Garmin Striker Vivid 7cv is a user-friendly fishfinder and depth finder designed to enhance your fishing experience with its 7-inch color display and intuitive interface. The vivid scanning sonar color palettes make it easy to distinguish between fish and underwater structures, providing a clear visual representation. The included GT20 transducer supports both traditional CHIRP sonar and CHIRP ClearVü scanning sonar, ensuring accurate and detailed readings of the underwater environment.

With high-sensitivity GPS, you can efficiently mark waypoints, create routes, and track your boat’s speed, making navigation straightforward and reliable. The built-in Quickdraw Contours mapping feature allows you to generate your custom maps with 1-foot contours, which is especially beneficial for anglers who frequent specific fishing spots. Additionally, Wi-Fi connectivity facilitates easy integration with the ActiveCaptain app, allowing you to transfer waypoints, receive smart notifications, and access community-sourced maps.

This connectivity feature can greatly enhance the functionality and user experience. The tilt/swivel mount provides flexibility in positioning the device, and the build is durable and designed to withstand harsh marine environments. However, the unit’s reliance on buttons rather than a touchscreen might be seen as less convenient for some users, especially those accustomed to modern touch interfaces. The device’s weight of 4.4 pounds could also be a consideration for users looking for a more lightweight option. Despite being released in 2020, it remains a competitive choice due to its robust feature set and reliable performance. The Garmin Striker Vivid 7cv is well-suited for anglers seeking a combination of advanced sonar capabilities, dependable GPS functionality, and ease of use in a durable package.

The Lowrance Eagle Eye™ 9 Live + C-MAP® is an advanced boat GPS depth finder, making it a strong candidate for fishing enthusiasts and boating aficionados. Its 9-inch IPS screen ensures excellent visibility from all angles, even when wearing polarized glasses, which is a significant advantage when out on the water. The device includes four sonar views (Live Forward, Live Down, CHIRP Sonar, and DownScan Imaging with FishReveal), providing comprehensive underwater imaging without requiring an additional module, which simplifies setup and use.

The autotuning live sonar with focused down and forward views further enhances the user experience by automatically adjusting settings for optimal performance. Additionally, the included detailed C-MAP charts for the US and Canada offer extensive mapping and charting capabilities, which is crucial for navigation and fishing trips. Connectivity is made easy with the new twist-lock connector system, allowing for straightforward installation on any boat or kayak.

The product's relatively high weight (3.05 kg package) could be a consideration for those with weight constraints. Also, some users might find the initial cost on the higher side, though it is reflective of the advanced features included. The one-year warranty offers some peace of mind, though a longer warranty might be preferable for some users. The Lowrance Eagle Eye™ 9 Live + C-MAP® is a powerful and feature-rich tool for serious boaters and anglers, offering advanced sonar technology, extensive mapping capabilities, and user-friendly design.

The Lowrance Elite FS 9 Fish Finder is a comprehensive tool designed for avid fishers. It features a 9-inch high-resolution, multi-touch screen which is both user-friendly and easy to install. The device excels in sonar technology, incorporating Active Imaging 3-in-1 sonar with CHIRP, SideScan, and DownScan along with FishReveal, providing detailed images of underwater structures and fish. Its support for ActiveTarget Live Sonar allows for real-time viewing of fish around structures, enhancing the fishing experience.

The preloaded C-MAP Contour+ charts cover 8,900 U.S. lakes with high-resolution 1-foot contours, aiding in precise navigation and spotting prime fishing areas like ledges and drop-offs. Connectivity is another strong point, with integrated wireless, NMEA 2000, and Ethernet connectivity enabling the addition of radar, outboard pilot, and data sharing between devices. The unit is built with durability in mind, including waterproofing to withstand harsh marine environments.

However, it's worth noting that the high level of detail in the sonar may be more than necessary for casual users, and the need for a separate S3100 module for Active Imaging HD could be seen as a drawback. Additionally, at a weight of 10 pounds, it is relatively heavy, which might affect portability. Despite these points, its high performance and robust feature set make it a strong candidate for serious anglers looking for a reliable and detailed fish finder.
