Key Features

The Raymarine RV-400 Series (RealVision 3D) transducers provide ultimate clarity and stability for inboard and outboard boats. Crafted with rugged stainless steel for fiberglass, wood, or metal hulls, these transducer pairs deliver DownVision™, SideVision™, High CHIRP, and RealVision 3D™ sonar in one low-profile package.

Each transducer includes a built-in Attitude and Heading Reference System (AHRS) that auto-stabilizes 3D sonar imagery even in rough conditions. The low-profile tilted-element design accommodates specific hull angles, eliminating the need for fairing blocks and reducing drag and cavitation.

With precise temperature sensing and wide-spectrum CHIRP performance, these through-hulls provide crystal-clear imaging for structure tracking, fish detection, and bottom mapping—ideal for serious fishermen and demanding navigators. The RV-400 All-In-One transducer (0° tilt) works well on boats with flat bottoms and trailerable boats.

They are compatible with Raymarine RealVision 3D sonar modules and Axiom Pro RVM chartplotters.
