Raymarine fishfinder & sonar – complete guide to RealVision, SideVision & CHIRP

Explore Raymarine's sonar technologies – RealVision 3D, SideVision, DownVision, and CHIRP – and learn how to choose the right transducer for your boat.

Raymarine offers a wide range of advanced sonar technologies for all types of boating and sport fishing. With Axiom and Axiom Pro, you get built-in RealVision™ 3D sonar that combines high performance with easy installation.

Choosing the right solution requires knowledge of different technologies, transducer types, and adapter cables. In this guide, we answer common questions and show which transducers work with each system and which cables are needed for a correct installation.

Raymarine's four sonar technologies

• RealVision™ 3D Sonar
• SideVision™ Sonar
• DownVision™ Sonar
• Digital / CHIRP Sonar

RealVision 3D Sonar

RealVision 3D is available on Axiom and Axiom Pro and provides a complete 3D image of the underwater world – bottom structure, fish, vegetation, and wrecks. With gyro-stabilization and an ultra-fast quad-core processor, you can rotate, zoom, and analyze the image in real-time. GPS tracking makes it possible to create an accurate 3D model of the area under the boat.

SideVision Sonar

With SideVision, you get crystal-clear images of fish and bottom structures up to 183 meters to each side. The technology is based on CHIRP signal processing for maximum range and detail.

DownVision Sonar

CHIRP DownVision provides photo-like images of bottom structures and fish. Perfect for anglers who want maximum detail.

• Photo-like images with CHIRP DownVision
• Dual channels for bottom structure and baitfish
• Compatible transducers for transom or thru-hull mounting

Digital / CHIRP Sonar

Digital Sonar with ClearPulse signal processing provides clear fish arches and automatic settings for all conditions. Perfect for both shallow and deep water.
