Raymarine CP370 Digital Sonar Module, 1kW, 50/200kHz, IPX6, 12/24V

Overview

The Raymarine E70297 is a CP370 Digital Sonar Module for adding ClearPulse traditional sonar to a compatible Raymarine multifunction display. It gives anglers a dedicated black box sonar setup with 50 kHz and 200 kHz operation, up to 1 kW RMS output depending on the connected transducer, and a depth range from 3 ft to 5,000 ft in optimum conditions.

This module is built for boats that need stronger bottom tracking and cleaner fish returns than an entry-level fishfinder can usually deliver. The 200 kHz channel suits shallower inshore work where target detail matters, while 50 kHz is used for deeper offshore water and wider bottom coverage.

The CP370 runs on 12 V or 24 V DC systems, with an operating voltage range of 10.8 V DC to 31.2 V DC. It connects to the boat electronics network through RayNet at 10/100 Mb/s and uses a separate transducer connection, so the transducer selection still needs to match the vessel, mounting location, and fishing style.

Key features

• ClearPulse digital sonar processing helps reduce noise and show fish targets through the water column with less manual adjustment.
• Up to 1 kW RMS power output supports serious coastal and offshore fishing when paired with the correct transducer.
• Fixed 50 kHz and 200 kHz channels cover common deep-water and inshore sonar use cases.
• Depth capability reaches up to 5,000 ft in optimum conditions, depending on the transducer and installation.
• IPX6 waterproof rating suits protected marine electronics locations that may still see spray or washdown exposure.
• RayNet network connection at 10/100 Mb/s links the module into compatible Raymarine display systems.
• 12 V and 24 V DC operation works with many small-boat and larger-vessel electrical systems.
• 5 A fuse rating and 30.6 W maximum power consumption help with planning the power circuit.

Compatibility and system fit

The CP370 is made to work as part of a Raymarine display and sonar system. It is compatible with Raymarine aSeries, cSeries, eSeries, eS Series, gS Series, C-Series Widescreen, E-Series Widescreen, E Classic, and G-Series multifunction displays.

A compatible transducer is required for full operation, and the transducer choice affects output power, mounting style, temperature or speed sensing, depth performance, and hull fit. The module supports transom, through-hull, and in-hull transducer installations when matched with suitable equipment.

Installation and setup

The module has separate connections for power, RayNet networking, and the transducer. A clean installation should keep cable routing planned before mounting, with enough service loop for future access and a protected location that limits heat, standing water, and unnecessary vibration.

The housing measures 205.6 mm high, 299.4 mm wide, and 84.4 mm deep, and weighs 1.44 kg. Those dimensions make it suitable for mounting behind a console, inside an electronics compartment, or in another dry service area where the network and transducer cables can be routed without strain.

Use cases on board

This sonar module is a good match for fishing boats that already use Raymarine multifunction displays and need dependable bottom tracking at speed, over canyons, or in deeper offshore water. It also suits coastal anglers who want a dedicated sonar module rather than relying only on sonar built into a display.

For the best result, the CP370 should be installed with attention to transducer placement, clean power, and proper cable routing. Those details matter on real boats, especially where aerated water, electrical noise, or poor transducer location can limit sonar performance.
