The inclusion of FishReveal helps in distinguishing fish from other objects, making it easier to identify targets. Additionally, the device supports ActiveTarget Live Sonar, providing real-time images of fish movements and reactions to lures, which can enhance the fishing experience considerably.

However, there are a few potential drawbacks. The device requires a 12 Volt DC power source, which may necessitate additional power management on smaller boats. While the product is feature-rich, its size and weight (approximately 4.53 kilograms) might affect portability for some users. Lastly, the price point might be on the higher side for casual or beginner anglers. The Lowrance Elite FS 9 is best suited for serious or professional anglers looking for advanced sonar capabilities and detailed underwater mapping.

The built-in high-sensitivity GPS lets you mark spots, create routes, and see your boat speed, which is helpful for navigation and returning to favorite fishing locations.
