Side Imaging Sonar Gain a 180 degree side-to-side perspective on the world below the surface with remarkable Humminbird® Side Imaging®. Ultra-thin beam scans the area up to 240 feet to the left and right of your boat location—for total coverage of up to 480 feet.
Down Imaging Sonar
Get a fish-eye's view of what's happening below your boat. Incredible images are created with High-frequency sound waves.
Exclusive Humminbird® SwitchFire™ puts anglers in complete command of how their sonar returns appear. With two unique display modes, you can adjust to your fishing conditions on the fly. Add or remove detail, account for water depth, temperature and turbulence.
Dualbeam Plus Sonar
Two beams combine for great detail and a wide coverage area. Use the narrow beam for high-accuracy returns and bottom. Use the wide beam when you want a larger search area.
GPS antenna built into the head unit
Access software updates to enhance the performance of your Humminbird unit through the My Humminbird section of Humminbird's site.
Dual Card Slots
Use one slot for advanced cartography and the other to save screenshots, sonar recordings and waypoints.
High Definition Display
Provides bright, crystal-clear images for easy viewing in harsh sunlight.
Built-in base map cartography that covers 3,000 US lakes with depth contours and many other locations without contours.
Rig up the ultimate fishing system. Use our 5-Port Ethernet switch to link together multiple Humminbird head units or share transducers.
HD Radar (Optional)
In darkness and fog, busy channels and treacherous weather, situational awareness is the name of the game.
Battle fish - not other boats. Humminbird's state of the art AIS technology takes the risk and guesswork out of navigating high-traffic channels or low-visibility seas.
