The Raymarine CP470 is a high-performance dual-channel CHIRP sonar module for Axiom, Axiom Pro, Axiom XL, and selected eS and gS displays. It supports 1kW or 2kW output depending on the transducer and covers 25-250kHz. This is an external module for an existing Raymarine system, not a complete fishfinder with a screen and transducer.

Dual-channel operation lets the boat run separate sonar frequencies or views at the same time, which is useful when moving between shallow structure and deeper water. The listed depth reaches up to 10,000 feet with an appropriate transducer and installation. Automatic Airmar XID transducer identification helps the system recognize compatible sensors. The CP470 connects through the Raymarine network, so display, network, transducer, and power planning should be done together.

Key Features

- High-performance dual-channel CHIRP – Allows two sonar channels to operate independently.
- 1kW or 2kW output – Matches the sounder power to the selected transducer.
- 25-250kHz frequency range – Provides broad frequency flexibility.
- Up to 10,000 feet depth capability – Gives the listed deep-water potential with suitable hardware.
- Airmar XID identification – Automatically identifies compatible transducers.

Who Is This For?

This Raymarine CHIRP sonar module suits offshore fishing boats and Axiom systems that need dual-channel sounder performance. It is not ideal for buyers without a compatible Raymarine display and transducer, because the CP470 has no screen and does not operate as a complete fishfinder alone.

Compatibility

Confirmed compatibility includes Raymarine Axiom, Axiom Pro, Axiom XL, a, c, e, eS, and gS series displays, compatible Airmar XID transducers, and Raymarine network connections. The supplied information does not identify NMEA 2000, NMEA 0183, Garmin, Simrad, Lowrance, radar, or autopilot compatibility. No named incompatible system was provided.

Warranty & Support

Raymarine provides a 3-year warranty with online registration. The supplied specifications do not state warranty exclusions or service procedures.

The CP470 is the Raymarine module for a boat that needs more sonar control than a standard internal sounder can provide. Its trade-off is the extra hardware and transducer planning, but dual-channel CHIRP gives the installer room to build a serious offshore system. Choose it for an existing Axiom network, not as a standalone sounder.
