Humminbird HELIX 10 CHIRP MEGA SI+ GPS G4N CHO Fish Finder Control Head

MEGA Side Imaging+, MEGA Down Imaging+, Dual Spectrum CHIRP, GPS & Ethernet Networking

The Humminbird CHIRP MEGA SI+ GPS G4N CHO is a professional-grade fish finder control head designed for anglers who want advanced sonar, GPS navigation, mapping, and network connectivity without purchasing an additional transducer. This Control Head Only (CHO) model is ideal for connecting to compatible built-in MEGA Imaging systems, accessory transducers such as MEGA 360 Imaging, or an existing Humminbird Ethernet network.

Featuring a large 10.1-inch display, the unit delivers detailed underwater imaging through MEGA Side Imaging+, MEGA Down Imaging+, and Dual Spectrum CHIRP sonar. Its internal GPS and enhanced Humminbird Basemap provide detailed navigation information, while AutoChart Live allows you to create real-time maps of your fishing areas.

High-speed Ethernet networking and One-Boat Network compatibility make the unit expandable into a larger fishing system, allowing compatible Humminbird, Minn Kota, and Cannon equipment to communicate and share information.

Key Features

Control Head Only Configuration

This CHO model does not include a transducer. It is designed for anglers who already have compatible sonar hardware or want to connect the control head to other compatible technologies.

The CHO configuration can be used with:

• Built-in MEGA Imaging on compatible Minn Kota trolling motors
• MEGA 360 Imaging and other accessory transducers
• Existing Humminbird Ethernet sonar networks

10.1-Inch Display with Keypad Control

The large 10.1-inch display provides a spacious viewing area for sonar, mapping, GPS, and navigation information. Keypad and soft-key controls provide direct access to preloaded views and menu functions.

MEGA Side Imaging+

MEGA Side Imaging+ provides crystal-clear Side Imaging coverage extending up to 200 feet on either side of the boat.

Compared with MEGA Side Imaging sonar, MEGA Side Imaging+ offers:

• Up to 20% more detail
• Up to 60% more range capability
• Enhanced fish and structure identification

MEGA Down Imaging+

MEGA Down Imaging+ provides detailed underwater views down to 200 feet below the boat.

Compared with MEGA Down Imaging sonar, MEGA Down Imaging+ provides:

• Up to 20% more detail
• Up to 60% more depth capability
• Enhanced views of fish and underwater structures

Dual Spectrum CHIRP Sonar

Dual Spectrum CHIRP sonar provides highly detailed fish arches and clear views of fish-holding structure and the bottom.

The system offers two search modes:

• Wide Mode: Maximum coverage
• Narrow Mode: Focuses on finer details

Dual Spectrum CHIRP is powered by Humminbird’s proprietary Low-Q CHIRP transducer when compatible transducer hardware is connected.

Internal GPS & Humminbird Basemap

The built-in GPS works with the enhanced Humminbird Basemap to provide navigation information including:

• Underwater terrain
• Contours
• Depth markers
• Buoys
• Day markers
• Hazards
• Marinas
• Points of interest

The included mapping coverage features charts for more than 10,000 lakes, along with coastal coverage for the continental United States.

AutoChart Live

Create real-time maps while navigating your fishing spots. AutoChart Live can map:

• Depth contours
• Bottom hardness
• Vegetation

The unit includes 8 hours of built-in recording time and supports AutoChart Zero Line SD cards for virtually endless AutoChart Live mapping capacity.

Premium Chart Compatibility

The fish finder supports optional premium chart solutions, including:

• Humminbird LakeMaster
• Humminbird CoastMaster
• Compatible Navionics charts

One-Boat Network Compatibility

The unit integrates with the One-Boat Network, allowing compatible Humminbird equipment to communicate with Minn Kota trolling motors and Cannon Optimum downriggers.

This provides opportunities for expanded boat control and fishfinding capabilities.

High-Speed Ethernet Networking

Built-in Ethernet networking allows you to create a powerful multi-device fishing system.

Ethernet can be used to connect multiple compatible fish finders and add technologies such as:

• Minn Kota i-Pilot Link
• Humminbird CHIRP Radar
• Additional compatible Humminbird networking equipment
