Keypad Control

Master HELIX at the touch of a button. Access the preloaded views from the user-friendly menu system, operated by soft-key controls that allow users to reliably operate the fish finder in any conditions.

MEGA Side Imaging+

See the world below like never before with a crystal-clear side imaging view out to 200 feet on either side of the boat. Users will unlock more fish and structures with 20% more detail and 60% more range capability than MEGA Side Imaging sonar.

MEGA Down Imaging+

Get unprecedented underwater clarity with Down Imaging coverage down to 200 feet below the boat. Users will unlock more fish and structures with 20% more detail and 60% more depth capability than MEGA Down Imaging sonar.

Dual Spectrum CHIRP Sonar

Before users cast, know what's down there thanks to highly-detailed fish arches and a clear view of the fish-holding structure and the bottom. Powered by Humminbird's proprietary Low-Q CHIRP transducer, the Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for focusing on the slightest detail.

Internal GPS and Humminbird Basemap

Humminbird's enhanced basemap provides users with a clear view of underwater terrain and surrounding points of interest, so users can fish and navigate with total confidence. Identify buoys, day markers, hazards, marinas, contours, depth markers, and much, much more. Includes charts of more than 10,000 lakes, plus coastal coverage for the continental U.S.

Premium Chart Compatible

Humminbird provides the most complete offering of premium chart options to anglers everywhere. Get a complete view of the world below with optional charts from Humminbird's LakeMaster® and CoastMaster™ products, as well as compatible Navionics® charts.

AutoChart Live

Create real-time maps of the fishing spots with access to patented Humminbird® LakeMaster® features. Map depth contours, bottom hardness, and vegetation as users drive the boat. It comes standard with eight (8) hours of built-in recording time and is compatible with AutoChart Zero Line SD cards for virtually unlimited AutoChart Live mapping capacity.

One-Boat Network Compatible

Many Humminbird models seamlessly integrate and communicate with Minn Kota and Cannon products to unlock more features and capabilities for anglers everywhere. Users can take advantage of the time on the water by using the exclusive boat control and fish-catching features of the One-Boat Network.

Ethernet Networking

High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fish finders, or upgrade to add-on technologies like Minn Kota i-Pilot Link and Humminbird CHIRP Radar.


Take control right from the screen of a Humminbird with wireless communication to compatible Talon and Raptor shallow water anchors, as well as Cannon Optimum downriggers. Additional features include wireless software updates from the Humminbird FishSmart App and the display of smartphone notifications on the Humminbird.

NMEA 2000 Networking Built-in

Connect an accessory NMEA 2000 network to a control head for even more information; from boat performance to weather and water conditions, make sense of it all with NMEA 2000 networking.


Includes control head, screen cover, transom-mount transducer, power cable, gimbal mounting bracket, and mounting hardware.
