Raymarine CP470 CHIRP Sonar Module

Raymarine CP470 | High-Performance CHIRP Authority

Raymarine CP470 addresses the requirement for superior target separation in offshore environments by utilizing a dual-channel 1kW CHIRP sonar engine capable of independent frequency adjustment. By integrating a high-dynamic-range digital receiver, the system mitigates acoustic noise and signal attenuation, providing clinical clarity of baitfish pods and individual predators at depths up to 10,000 feet. This engineering focus ensures that professional navigators can distinguish between the thermocline and bottom-dwelling species with absolute certainty, preventing tactical errors during deep-water pelagic tracking.

From a system integration standpoint, the CP470 requires a RayNet (Ethernet) connection to Axiom or GS-Series displays to process its high-bandwidth data stream. In demanding marine environments, it is vital to ensure the transducer is correctly matched to the unit’s 1kW output to avoid impedance mismatching. System performance relies on clean power; don’t share the unit’s power circuit with high-draw windlasses, as digital noise can induce signal “aliasing” on the high-gain sonar scroll, masking critical targets near the sea floor.
