Raymarine RV-400 Stainless Steel Thru-Hull RealVision 3D 0°

The Raymarine RV-400 Stainless Steel Thru-Hull RealVision 3D 0° transducer is purpose-built for anglers and boaters who demand the clearest underwater imaging available. This forward-looking sonar unit combines multiple advanced sonar technologies—RealVision 3D, CHIRP DownVision, SideVision, and high-frequency CHIRP sonar—into a single, compact thru-hull housing. Whether you're sight-fishing shallow flats, mapping structure in deeper water, or navigating tight channels, the RV-400 delivers the real-time clarity needed to locate fish and obstacles with confidence.

Built from rugged stainless steel, the RV-400 is engineered to withstand saltwater and freshwater environments alike, resisting corrosion in the harshest marine conditions. The low-profile thru-hull design minimizes drag while maintaining structural integrity, and the 0° forward-facing orientation provides intuitive head-on perspective of what lies ahead. The integration of RealVision 3D technology delivers photorealistic 3D imagery that transforms how you interpret the underwater environment, while CHIRP sonar modes ensure precise target separation and bottom definition at multiple frequency ranges.

The RV-400 integrates seamlessly with compatible Raymarine navigation and sonar systems, making it ideal for anglers upgrading existing glass-cockpit setups or outfitting new builds. Installation requires professional thru-hull mounting to ensure proper seal and performance. Serious tournament anglers, recreational boaters, and commercial fishing operations all benefit from the RV-400's superior target definition and real-time environmental awareness. With dimensions of 14 x 6 x 17 inches and a weight of 10.55 pounds, proper installation planning and equipment are essential for optimal results.
