Discover Crystal-Clear Underwater Views with the Raymarine RV-212S Starboard Thru-Hull Transducer

Imagine gliding across the water, pinpointing fish and mapping the seabed in stunning 3D detail, no matter how your boat pitches or rolls. The Raymarine RV-212S bronze thru-hull transducer, angled at 12 degrees for starboard-side installation on deep-V hulls, makes this a reality for serious anglers and powerboat enthusiasts. Paired with its port-side counterpart, this low-profile sensor delivers RealVision 3D sonar that transforms your marine electronics setup into a powerful fishfinding tool. Crafted from durable cast bronze, it's built to handle the rigors of saltwater environments while slipping through the water with minimal resistance.

What sets this transducer apart is its all-in-one design, packing four advanced sonar channels into a single, streamlined unit. From high-frequency CHIRP for precise fish targeting to DownVision and SideVision for detailed bottom mapping, you'll uncover hidden structures, wrecks, and schools of fish that traditional 2D sonar might miss. Anglers report spotting baitfish balls and game fish lurking in cover with ease, turning average outings into trophy hauls.

Advanced Sonar Technology for Real-World Fishing Success

At the heart of the RV-212S lies Raymarine's innovative RealVision 3D sonar, which renders the underwater world in lifelike, photorealistic images. Unlike flat sonar screens, this technology creates a navigable 3D model of the seafloor, letting you rotate, zoom, and inspect features from any angle. The built-in Attitude and Heading Reference System (AHRS) is a game-changer—it senses your boat's heel, pitch, and yaw in real time, stabilizing the imagery to eliminate distortions from waves or turns.

Key sonar modes include:

• High-Frequency CHIRP: Locks onto individual fish with exceptional target separation, ideal for depths up to hundreds of feet.
• DownVision: Provides photo-like clarity of the bottom directly beneath your hull, revealing contours, drop-offs, and vegetation.
• SideVision: Scans up to 600 feet to each side, helping you prospect vast areas for structure and fish without constant repositioning.
• RealVision 3D: Combines all channels for immersive views, perfect for navigating rocky bottoms or tight coves.

Plus, the integrated fast-response temperature sensor tracks water conditions instantly, helping you correlate bites with thermal layers or migrations. This data overlays seamlessly on compatible Raymarine multifunction displays, giving you a complete picture at a glance.

Effortless Installation on Deep-V Hulls

Designed specifically for the starboard side of deep-V hulls, the RV-212S's 12-degree deadrise angle ensures optimal beam projection without a fairing block. Boat owners love how its low-profile bronze housing mounts flush, reducing drag and preventing cavitation that could spook fish or wear down your hull. Installation is straightforward: drill a precise hole, bed it in sealant, and secure with the included nut—no complex fairings or protrusions to snag lines or complicate trailering.

Suitable for fiberglass or wooden hulls up to several inches thick, this thru-hull thrives in demanding marine conditions. With a compact 2-meter cable, routing is simple, keeping your deck clutter-free. Pro tip: Position it forward of props and struts for cleanest readings, and always pair with the port-side model (RV-212P) for balanced 3D coverage on symmetric hulls.

Many users on planing hulls note improved performance at speed, as the bronze material resists fouling better than plastic alternatives, maintaining accuracy over long seasons.

Why Bronze Thru-Hull Beats the Rest for Powerboaters

Bronze construction isn't just tough—it's corrosion-resistant in saltwater, with a proven track record in commercial fishing fleets. Unlike plastic transducers that can warp or delaminate, this cast-bronze unit holds its shape, ensuring consistent performance year after year. The thru-hull design outperforms in-hull or transom mounts by delivering undistorted beams, crucial for reliable 3D sonar in choppy seas.

For trailered boats, the sleek profile means no removal hassles; it tucks neatly without road rash risks. Powerboat captains appreciate the drag reduction, squeezing extra knots from their engines while enjoying quieter operation. Backed by Raymarine's reputation for marine innovation, this transducer integrates flawlessly with Element, Axiom, and other MFDs supporting RealVision processing.

Maximize Performance: Tips from Seasoned Skippers

To get the most from your RV-212S:

1. Calibrate AHRS: Run the auto-setup routine in calm water for peak stabilization.
2. Adjust Gain Settings: Dial in CHIRP sensitivity for your target species—higher for offshore pelagics, moderate for inshore structure.
3. Clean Regularly: Wipe the face monthly to prevent marine growth; bronze sheds growth slower but stays vigilant.
4. Pair with Networking: Connect via SeaTalk or Ethernet for dual-transducer fusion on larger screens.
5. Monitor Temps: Use the sensor data to time your drifts around thermoclines where fish stack up.

Feedback from users highlights fewer false readings in debris-heavy waters, thanks to Wide Spectrum CHIRP filtering clutter effectively.
