What customers say
The Raymarine CP470 CHIRP Sonar Module is highly regarded for its exceptional performance, offering superior target separation and deep penetration ideal for offshore fishing. Anglers appreciate its ability to clearly distinguish fish and structure, significantly enhancing fishing success. The module integrates seamlessly and reliably with Raymarine MFDs, providing excellent detail coverage through its dual CHIRP channels. While it represents a significant investment, especially with the addition of high-performance transducers, committed users find the CP470 to be a reliable, top-tier sonar solution that justifies the cost through its consistent, professional grade results.
Know before you buy
The CP470 uses wide-spectrum CHIRP technology, which sends a continuous sweep of frequencies rather than a single pulse. This results in significantly higher resolution, better target separation, and the ability to distinguish individual fish within dense schools or near the bottom.
Yes, the CP470 is specifically engineered for offshore conditions. Its advanced sensitivity and noise-filtering capabilities allow it to maintain reliable bottom tracking and clear imagery even at significant depths.
The CP470 is designed to integrate with Raymarine’s range of multi-function displays. You should ensure your current display is compatible with external sonar modules via RayNet before installation.
The module features built-in signal processing that actively filters out surface clutter and interference. This helps maintain a clean, stable image on your screen even when the boat is pitching or rolling in choppy conditions.
The CP470 requires a compatible CHIRP-capable transducer to function correctly. If your current transducer is a standard non-CHIRP model, you will likely need to upgrade it to take full advantage of the module's wide-spectrum capabilities.
The CP470 operates on a voltage range of 12 to 24 VDC and has a power consumption of 30.6 watts. It is designed to be wired directly into your vessel's power system.
