Humminbird HELIX G4N Fish Finder

MEGA Down Imaging provides significantly higher frequency sonar, resulting in near-photographic clarity of structure and fish directly beneath your boat. It is particularly effective for identifying specific objects like brush piles or rock formations down to 125 feet.

Yes, it includes the Humminbird Basemap, which provides depth contours and navigation data for thousands of lakes and coastal areas. You can also use the AutoChart Live feature to create your own detailed, real-time maps of uncharted waters.

Absolutely. The G4N model is designed for connectivity, featuring Ethernet, Wi-Fi, Bluetooth, and NMEA 2000 support. This allows it to integrate seamlessly into the One-Boat Network, letting you share sonar data, waypoints, and even control compatible trolling motors.

The HELIX G4N series uses a dedicated keypad control interface rather than a touchscreen. Many anglers prefer this design because it offers reliable, tactile operation that works consistently even when your hands are wet, cold, or covered in fish slime.

Dual-Spectrum CHIRP sweeps a wider range of frequencies, which produces much higher resolution and clearer target separation than traditional sonar. This makes it easier to distinguish individual fish from the surrounding structure or bait balls.

The unit comes with 8 hours of built-in recording time for AutoChart Live. If you need more, you can expand this capacity by using a compatible Zero Line SD card.
