Raymarine CP370 CHIRP Sounder Module – 600W/1000W | Enhanced Digital Filtering | RAY-E70297

Professional Fish-Finding Sonar — Added to Your Raymarine Display

The Raymarine CP370 CHIRP Sounder Module adds professional-grade sonar capability to compatible Raymarine multifunction displays, turning your chartplotter into a high-performance fishfinder without replacing the display itself. Where a standard sounder shows you a rough picture of what’s below, the CP370’s enhanced digital filtering and smarter target intensity controls reveal individual fish targets, bait schools, and bottom structure with exceptional clarity — through the entire water column, not just near the surface.

The CP370 takes the guesswork out of reading the sonar display. Target intensity is automatically optimised so bait and game fish stand out clearly against the background, letting you focus on fishing rather than interpreting the screen. With 600W or 1000W output depending on the transducer connected, it delivers the power needed to reach depth in both coastal and offshore fishing scenarios.

The module connects to your Raymarine MFD via the vessel’s network, with sonar data displayed directly in the LightHouse chart application alongside your navigation chart, waypoints, and AIS targets.

⚠️ Transducer required: The CP370 requires a compatible transducer (sold separately). Power output — 600W or 1000W — depends on the transducer connected. Confirm transducer compatibility before ordering.

Best use case: The CP370 is the right choice for anglers with a compatible Raymarine MFD who want to add or upgrade their sonar capability without replacing the display. It’s particularly well suited to boats where the existing display is a non-sonar Axiom or a legacy Raymarine MFD that supports an external sounder module — the CP370 adds professional-grade fish-finding performance to a display the owner already knows and trusts. The enhanced digital filtering and target intensity controls make a noticeable difference for offshore and deep-water fishing where distinguishing fish from bottom structure and thermocline layers is critical. At 600W/1000W output (transducer dependent), it has the power for serious depth penetration in both inshore and offshore applications.

Heads up: A compatible transducer is required and sold separately — the CP370 does not include a transducer. Power output depends entirely on the transducer connected: a 600W transducer delivers 600W, a 1000W transducer delivers 1000W. Confirm your display model is compatible with the CP370 before ordering — the Axiom 2 Pro RVM models have built-in sonar and do not require this module. Contact us with your display model if you need compatibility confirmation.
