10 Best Depth Finders 2025 in the United States

The Garmin ECHOMAP UHD2 94sv depth-finder is designed with a focus on ease of use and comprehensive functionality for boating and fishing enthusiasts. The product features a 9-inch bright touchscreen display that ensures clear visibility even in direct sunlight, which is a crucial factor when navigating on water. The display size and resolution of 1024 x 600 provide adequate detail for chart plotting, although some users may prefer a higher resolution for more detailed images.

One of its standout features is the GT56-TM transducer which supports Garmin's traditional sonar as well as ClearVü and SideVü scanning sonars. This offers a wide range of scanning capabilities useful for detecting fish and underwater structures. The inclusion of CHIRP technology enhances target separation and provides clear images, making it well-suited for serious anglers.

The built-in Garmin Navionics+ coastal charts with integrated Navionics data offer comprehensive navigation support, which would be particularly beneficial for those fishing or boating along U.S. coastal areas. The unit's built-in Wi-Fi connectivity allows for seamless sharing of sonar data and navigation routes with other ECHOMAP UHD2 devices, which facilitates collaborative fishing trips or group navigation. Another notable feature is its wireless connectivity with Garmin’s Force trolling motor, allowing for advanced control such as creating routes and adjusting speed directly from the chartplotter, which can enhance the fishing experience.

While weighing 8.08 pounds, the device might be less portable compared to smaller units, but its mounting options (dashboard or panel) can accommodate different types of watercraft. Considering its features, the Garmin ECHOMAP UHD2 94sv depth-finder is an excellent choice for those who prioritize comprehensive sonar capabilities and detailed navigation, especially in coastal areas.

The Lowrance Eagle Eye 9 Live is a versatile depth finder designed especially for anglers and boating enthusiasts who want detailed underwater views without complicated setup. Its 9-inch IPS screen is bright and easy to read from various angles—even with polarized sunglasses on—which is great for outdoor use. The included Eagle Eye transducer supports four sonar views simultaneously, including CHIRP sonar and DownScan Imaging with FishReveal, providing clear images of fish and structure beneath the water. This all-in-one sonar feature means you don't need extra modules, simplifying installation and use.

The device comes preloaded with C-MAP inland charts covering over 17,000 US lakes, and it offers Genesis Live mapping to create your own detailed maps on the spot. The autotuning live sonar suggests it adjusts well to different conditions, which helps get accurate readings. The twist-lock connector system makes installation straightforward, suitable for both boats and kayaks, adding to its portability. It runs on battery power, which may require monitoring to avoid running out mid-trip. Also, while it includes GPS integration through its chart features, it may lack some advanced navigation functions found in higher-end models.

The plastic build keeps the unit lightweight but may be less rugged in extreme conditions. With a strong user reception, the Eagle Eye 9 Live represents a dependable choice for those who want detailed, real-time sonar imaging on a medium-sized, easy-to-handle device without fuss. It is best suited for freshwater fishing on lakes and smaller boats where portability and clear visuals are priorities.

The Simrad NSS12 Evo3S is a high-quality depth-finder and chartplotter designed for serious anglers and boaters who want a reliable and feature-rich device. Its 12-inch high-definition screen makes it easy to see detailed maps and sonar images, which is great for spotting fish and underwater structures. The device uses a powerful iMX 8 processor, so it responds quickly and handles complex sonar data smoothly, helping you find fish with clearer images. It includes built-in GPS navigation with preloaded C-MAP US charts, making it convenient for inland and coastal trips without needing extra map purchases.

This model supports advanced sonar technologies like Active Imaging and StructureScan 3D, offering highly detailed views below the water surface. Bluetooth connectivity allows integration with other boat systems, like engine monitoring and audio control, turning the NSS12 Evo3S into a central hub for your vessel. The touchscreen is responsive and works well in various weather conditions; plus, there’s a keypad with a rotary dial for precise control if you prefer physical buttons.

On the downside, the device is somewhat bulky and requires a bracket mount, which may affect portability and installation on smaller boats. While it excels in features and performance, it sits at a higher price point that might be too much for casual users or those who only need basic depth reading. Also, some users might find the array of functions overwhelming if they're not interested in advanced integration or 3D sonar imaging. This makes the Simrad NSS12 Evo3S most suitable for anglers and boat owners looking for a robust, all-in-one depth finder and navigation tool with excellent display quality, GPS, and sonar capabilities. If you want a powerful, expandable device to enhance your fishing or boating experience, this model offers great value with its advanced features and ease of use. However, if you need something simple and portable, there might be lighter or less expensive options to consider.
