The Humminbird 411370-1 Helix 9 Chirp MEGA DI+ GPS G4N is a powerful fish finder with a 9" display and advanced features. It is equipped with MEGA Down Imaging+ technology, Dual Spectrum CHIRP sonar, and an internal GPS with Humminbird Basemap.

One of the standout features of the HELIX 9 CHIRP MDI+ GPS G4N is its keypad control. With the touch of a button, you can access preloaded views from the user-friendly menu system. The soft key controls allow you to operate the fish finder reliably in any conditions.

MEGA Down Imaging+ provides unprecedented underwater clarity. It offers Down Imaging coverage down to 200 feet below your boat and provides 20% more detail and 60% more depth capability than MEGA Down Imaging sonar. This means you can unlock more fish and structure, giving you a clear view of what's beneath the surface.

The Dual Spectrum CHIRP sonar feature allows you to see highly-detailed fish arches and get a clear view of fish-holding structures and the bottom. Powered by the Low-Q CHIRP transducer, Dual Spectrum offers two search modes. The Wide Mode provides maximum coverage, while the Narrow Mode allows you to focus on the slightest detail.

Bluetooth connectivity is another great feature of the Humminbird 411370-1 Helix 9 Chirp MEGA DI+ GPS G4N. You can take control directly from the screen of your fish finder with wireless communication to compatible Talon and Raptor shallow water anchors, as well as Cannon Optimum downriggers. Additionally, you can receive wireless software updates from the Humminbird FishSmart App and display smartphone notifications on your Humminbird device.

The fish finder also has NMEA 2000 networking built-in, allowing you to connect an accessory NMEA 2000 network for even more information. From boat performance to weather and water conditions, you can make sense of it all with NMEA 2000 networking.
