Display Quality

The Lowrance Elite FS 9 features a high-resolution 9-inch touchscreen display that is well-regarded for its clarity and detail.

The 9-inch screen provides ample space to view the sonar returns, maps, and other data without feeling cluttered, which is especially beneficial when you need to quickly glance at the finder to interpret the underwater environment. A larger screen also allows for better split-screen views, so you can simultaneously monitor different types of information, such as CHIRP sonar and DownScan imaging or maps and sonar, without sacrificing detail.

The touchscreen functionality on the Elite FS 9 enhances the user experience by making it easier and faster to navigate through menus, adjust settings, and pinpoint locations on the map. Touchscreens are particularly helpful when you need to zoom in on a map or quickly switch between different views. It’s designed to be responsive, which means you can use it even with wet hands, a common situation while fishing. However, in certain conditions, such as when there’s heavy rain or if you’re wearing thick gloves, the touchscreen might be less convenient than traditional button controls.

The benefits of a big screen and a touchscreen interface are most pronounced when fishing in areas where detail is critical. For instance, when you’re trying to follow contours and edges where fish are likely to be, or when you’re trying to distinguish between fish and structure, the high-resolution display can provide clearer images and better differentiation. 

Sonar Performace

The Lowrance Elite FS 9 comes with the Active Imaging 3-in-1 transducer. This transducer provides three types of sonar:

1. CHIRP Sonar

The image below displays the screen of a Lowrance Elite FS 9 showing the CHIRP Sonar readings. The fish finder is set to a general mode with an automatic depth range of 40 feet and uses a frequency of 200kHz, which is typical for high-resolution imaging in relatively shallow water.

The sonar returns are clear and there is a distinct contrast between different elements within the water column, which is indicative of a high-quality sonar system. The distinct arches demonstrate that the CHIRP sonar is effectively identifying fish with good target separation, and the detail on the bottom contour indicates that the unit is providing a detailed look at the bottom structure.

Moreover, the color differentiation is sharp, with different intensities readily apparent, which is crucial for anglers to determine bottom hardness and locate fish. The screen is also showing minimal surface clutter, suggesting that the unit’s noise rejection capabilities are functioning well.

In summary, the CHIRP sonar of the Elite FS 9 delivers detailed and useful information to the anglers, which is what you would expect from a modern fish finder in this class.

2. DownScan Imaging

When it comes to imaging, the Elite FS DownScan offers clarity at both 800 kHz and 455 kHz frequencies. At 800 kHz, you’ll get superior resolution images, making it easier to spot fish close to the bottom or around structures in shallow water. The 455 kHz frequency allows for deeper penetration, up to 300 feet, which is beneficial for identifying fish-holding areas in deeper water.

When fishing in shallow waters, the 800 kHz frequency setting on the DownScan gives you a very clear and detailed image of the underwater environment. This can be crucial for spotting species that prefer to stay close to the bottom or near structures, such as bass around submerged trees or crappie in and around weed beds.

For species that are structure-oriented, such as snapper or grouper, the DownScan fish finder can help you identify ledges, drop-offs, and reefs where these fish are likely to be found. By providing high-resolution images, you can pinpoint the exact locations of these structures and the fish that are holding to them.

3. SideScan Imaging

SideScan in Elite FS 9 offers detailed views up to 150 feet on each side of the boat at 800 kHz for high definition imagery in shallow water, and up to 300 feet with the 455 kHz setting for extensive side coverage in deeper water.

Using the 800 kHz frequency, Lowrance SideScan provides a high-resolution image of the underwater structure where species like bass, pike, or panfish might hide or feed. Anglers can see weed lines, submerged trees, rocks, and even individual fish, allowing for precise casting.

For fish that school in open water, like crappie or certain saltwater species, Elite FS 9 can help locate the schools off to the side of the boat, so you can position yourself for optimal casting or trolling without spooking the school by driving directly over them.

The 455 kHz frequency gives a broader, deeper view, which is great for identifying ledges, drop-offs, and other deep structures favored by species like catfish, walleye, or certain types of saltwater fish.

GPS and Mapping

The Elite FS 9 is equipped with advanced mapping features that significantly enhance the fishing and boating experience. The unit comes with preloaded high-detail C-MAP Contour+ inland and coastal charts, which offer a wealth of information such as depth contours, spot soundings, and navigational aids. This comprehensive mapping allows anglers to pinpoint the most promising fishing spots, such as drop-offs, channels, and potential structures where fish are likely to congregate.

For boating, the mapping features assist in safe navigation, allowing boaters to avoid potential hazards and navigate through unfamiliar waters with greater confidence. The GPS functionality also allows for route planning, tracking, and saving waypoints, which simplifies the process of returning to successful fishing spots or navigating through frequently traveled routes. 

The mapping tools, when combined with the sonar capabilities, transform the Elite FS 9 into a robust fish finder GPS combo for both successful fishing and safe, efficient boating.
