Raymarine RV-420 Stainless Steel Thru-Hull RealVision 3D 20° - Pair Product Description

Raymarine RV-420 Stainless Steel Thru-Hull RealVision 3D Transducer System - 20° Pair

Transform your underwater vision with Raymarine's most advanced dual-transducer system. The RV-420 Stainless Steel Thru-Hull RealVision 3D transducer pair delivers unprecedented underwater clarity through cutting-edge CHIRP sonar technology, providing 180° coverage that eliminates blind spots around deep keels and underwater obstructions.

Engineered for serious anglers and navigation professionals, this NMEA-compliant transducer system combines DownVision™, SideVision™, high-frequency CHIRP fish targeting, and revolutionary RealVision 3D™ sonar in a rugged stainless steel through-hull design. The integrated Attitude and Heading Reference System (AHRS) automatically compensates for vessel motion, delivering crystal-clear imagery even in challenging sea conditions.

Advanced Sonar Technology Features

  • 4-Channel Wide Spectrum CHIRP Technology: 50-60/200-350kHz dual-frequency operation for superior target definition and fish identification
  • RealVision 3D™ Sonar Integration: Life-like three-dimensional underwater imaging that reveals structure details invisible to traditional sonar
  • Integrated AHRS Stabilization: Built-in attitude and heading reference system eliminates motion-induced distortions from waves and vessel maneuvering
  • 360° Underwater Coverage: Port and starboard transducer configuration provides complete 180° sonar coverage, ideal for deep-keel vessels
  • Fast-Response Temperature Sensor: Precision water temperature monitoring for enhanced fishing success and navigation safety

Ideal Applications

  • Offshore sport fishing vessels requiring maximum underwater coverage
  • Commercial fishing operations demanding precise fish location capabilities
  • Navigation-critical vessels operating in complex underwater terrain
  • Deep-keel sailboats and displacement hulls with significant underwater obstructions
  • Professional charter boats requiring reliable, high-performance sonar systems

Why Choose the Raymarine RV-420 System?

This isn't just another transducer upgrade – it's a complete underwater vision transformation. The RV-420's dual-transducer design eliminates the coverage gaps that single-unit systems can't address, while RealVision 3D technology provides the kind of underwater detail that transforms both fishing success and navigation confidence. With AHRS stabilization and wide-spectrum CHIRP technology, you're investing in marine electronics that perform consistently in any conditions.

Frequently Asked Questions

What hull deadrise angles does the RV-420 accommodate without fairing blocks?

The RV-420 features internal 20° tilt that accommodates hull deadrise angles from 13° to 20° without requiring custom fairing blocks, significantly simplifying installation.

Can I use the RV-420 system on a trailered boat?

Yes, the RV-420's near-flush, low-profile design is specifically engineered to work excellently on trailered boats without causing drag or performance issues during transport.

What's the difference between single transducers and this dual-transducer system?

The dual-transducer configuration provides complete 180° underwater coverage by positioning one transducer for port/down coverage and another for starboard/down coverage, eliminating blind spots around deep keels and underwater obstructions that single units cannot address.

Is professional installation required for the RV-420 system?

While the system includes comprehensive installation instructions and mounting templates, thru-hull installations require cutting holes in your vessel's hull. We recommend professional installation by ABYC-certified marine technicians to ensure proper sealing and optimal performance.

Which Raymarine displays are compatible with the RV-420?

The RV-420 is designed exclusively for Raymarine Axiom RealVision multifunction displays and integrates seamlessly with NMEA 2000 networks for comprehensive vessel data sharing.

Raymarine’s RV-400 stainless steel all-in-one through hull transducer is designed for inboard and outboard powerboats.
