Raymarine CP470 CHIRP Sonar Module, 2kW, 25-250kHz, 12/24V, IPX6

Overview

The Raymarine E70298 is a CP470 2 kW CHIRP sonar module for adding high-resolution fishfinder capability to a compatible Raymarine multifunction display. It uses two adjustable CHIRP sonar channels across a 25 kHz to 255 kHz frequency range, giving offshore anglers the detail needed to separate fish, bait, thermoclines, and bottom structure in deep water.

The module runs on 12 V dc or 24 V dc systems, with an operating voltage range of 10.8 V dc to 31.2 V dc and maximum power consumption of 30.6 W. Depth capability reaches up to 3,000 m or 10,000 ft depending on the connected transducer, so the final installation should be matched with the right low, medium, or high CHIRP transducer for the boat and fishing grounds.

With an IPX6 waterproof rating, RayNet networking, and a separate transducer connection, the CP470 is built for remote mounting in an electronics locker, console, cabin, or other protected onboard location where it can stay connected to the vessel network while keeping sonar processing separate from the display.

Key features

• Wide-spectrum CHIRP sonar module with up to 2 kW maximum output, depending on the transducer used.
• Dual adjustable CHIRP channels support independent viewing and control on compatible Raymarine multifunction displays.
• Tracks fish, bait, and bottom structure down to 3,000 m or 10,000 ft when paired with a suitable transducer and installation.
• Frequency coverage from 25 kHz to 255 kHz works with optional low, medium, and high CHIRP transducers in standard or wide-beam options.
• TruZoom magnification shows extra target detail without reducing sonar image resolution.
• RayNet 10 / 100 Mb/s network connection links the module to compatible Raymarine displays.
• 12 V dc and 24 V dc system support, with a 10.8 V dc to 31.2 V dc operating voltage range.
• IPX6 waterproof rating helps the unit handle spray and wet marine environments when installed correctly.
• Compact black box form factor measures 205.6 mm high, 299.4 mm wide, and 84.4 mm deep.

Installation and setup

The CP470 is a black box module, so it is normally mounted away from the helm display and connected into the boat electronics system. It has dedicated connections for power, RayNet networking, and the transducer, which keeps the wiring layout straightforward during a new install or sonar upgrade.

A 5 A fuse rating is specified for the power circuit. The unit also draws up to 3 A RMS, so cable routing, circuit protection, and grounding should be handled carefully, especially on boats with long DC cable runs or mixed 12 V and 24 V equipment.

The housing weighs 1.54 kg or 3.39 lb. Mount it where the cables can be supported properly and where the module is protected from physical impact, standing water, and unnecessary heat while still allowing access for service.

Compatibility and fit

The CP470 connects to Raymarine chartplotter and multifunction display systems through RayNet. It is compatible with Raymarine aSeries, cSeries, eSeries, and gS Series displays, and it also works within Raymarine LightHouse display environments that support CP470 sonar control.

Transducer choice has a major effect on the sonar result. Low CHIRP is commonly used for deeper water and broad bottom coverage, while medium and high CHIRP are more often used where target detail and bait separation are the priority. Standard and wide-beam transducer options allow the setup to be matched to offshore trolling, bottom fishing, canyon runs, or coastal fishing.

Use cases on board

This module suits boats that need more sonar power and target detail than a basic built-in fishfinder can deliver. It is a strong match for offshore center consoles, sportfishing boats, larger pilothouse boats, and serious coastal fishing setups already using compatible Raymarine displays.

The CP470 is especially useful when the crew needs to read through bait, hold bottom in rough conditions, or compare sonar views from two CHIRP channels at the same time. It is not a standalone display, so it should be bought as part of a complete Raymarine display, network, and transducer system.
