Frequently Asked Questions

What does CHO mean and what transducer do I need?

CHO stands for Control Head Only, meaning this unit does not include a transducer. It's designed to work with built-in transducers on Minn Kota trolling motors, existing network transducers, or separately purchased Humminbird transducers compatible with MEGA Down Imaging and CHIRP sonar.

Can I connect this to my Minn Kota trolling motor?

Yes, this CHO model is ideal for connecting to Minn Kota trolling motors with built-in MEGA Down Imaging or Universal Sonar 2 transducers. It also supports i-Pilot Link integration for GPS trolling motor control.

What's the difference between MEGA DI and standard down imaging?

MEGA Down Imaging operates at 1.2 MHz frequency providing up to 3X more detail than standard 455 kHz down imaging. This higher frequency delivers photo-like clarity of underwater structure, cover, and fish with exceptional resolution down to 75 feet.

Can I network multiple HELIX units together?

Yes, all HELIX 7 G4N models support Ethernet networking, allowing you to connect multiple units and share sonar, GPS, and chart data across your entire system. This creates a comprehensive fishing network throughout your boat.

How does AutoChart Live mapping work?

AutoChart Live creates real-time maps as you drive your boat, recording depth contours, bottom hardness, and vegetation. It includes 8 hours of built-in recording time and is compatible with AutoChart Zero Line SD cards for unlimited mapping capacity.
