Product Overview

Raymarine CP100 CHIRP DownVision™ Sonar Module

Raymarine's new CP100 CHIRP DownVision™ Sonar Module brings powerful sonar imaging capability to Raymarine's full line of networkable multifunction displays.

Two sonars in one, the CP100 features Raymarine's CHIRP fish targeting as well as the photo-like CHIRP DownVision™ sonar. The CP100 interfaces to the RayNet (Ethernet) network enabling the CP100 to be accessed from any Raymarine network display.

Unlike conventional imaging sonars that transmit on a single frequency with each pulse, the CP100's DownVision™ sonar uses CHIRP technology to transmit across a wide spectrum of sonar frequencies with each pulse ? the result is much higher-resolution, life-like sonar images.

CP100's fish targeting channel features amazing resolution enabling it to easily separate individual baitfish in a school, and distinguish the bait from predator species. Best of all, the CHIRP fish targeting can be viewed simultaneously with CHIRP DownVision™ for the ultimate view of what is underneath the water.

The ultra-compact CP100 CHIRP DownVision Sonar Module is compatible with all Raymarine a-Series, c-Series, e-Series and gS-Series multifunction displays. The CP100 is available bundled with the CPT-100 transom mount transducer. The CP100 Sonar module only (no transducer included) can be paired with optional plastic or bronze thru hull transducers.

Key CP100 Features:

  • Photo-like imagery of bottom structure using CHIRP DownVision™.
  • CHIRP powered dual channel sonar; view high resolution DownVision structure imagery and target fish with CHIRP sonar simultaneously.
  • Perfectly matched transom mount and through hull CHIRP transducers available.
  • Fast response temperature sensor built into the transducer.
  • Maximum depth 600 feet for both channels.
  • Simple RayNet Ethernet connection to Raymarine models for 2013 a, c, e and gS Series MFDs.
  • Optional RayNet network cable required to complete installation:
    • 2 meter Raynet cable part number A62361
    • 5 meter RayNet cable, part number A80005

Expert Overview

The Raymarine CP100 DownVision Module (part number E70204) is a CHIRP sonar module designed for integration with Raymarine networkable multifunction displays. This module provides dual-channel sonar capabilities, offering both high-resolution DownVision imagery for bottom structure and CHIRP fish targeting. It utilizes CHIRP technology to transmit across a wide spectrum of sonar frequencies, resulting in detailed, photo-like underwater images and improved separation of individual fish. This product is suitable for marine professionals and enthusiasts who require advanced sonar imaging to identify baitfish, distinguish predator species, and visualize underwater structures. The CP100 connects to a RayNet (Ethernet) network, allowing access from compatible Raymarine a-Series, c-Series, e-Series, and gS-Series multifunction displays. This specific offering does not include a transducer, providing flexibility for users to pair it with optional plastic or bronze thru-hull transducers based on their vessel requirements. It addresses the need for enhanced underwater visibility and target identification for navigation and fishing applications.
