Raymarine Pack of RV-412 RealVision 3D Stainless Steel Thru Hull Txds, Port & Starboard 12°, Direct connect to AXIOM (2 x 2m, Y-cable and 8m extension cable)

Raymarine Pack of RV-412 RealVision 3D Stainless Steel Thru Hull Txds

Raymarine Pack of RV-412 RealVision 3D Stainless Steel Thru Hull Txds are the professional's choice for inboard and outboard powerboats, offering a rugged, low-profile solution that eliminates the need for bulky fairing blocks. By using a split-pair configuration—one transducer for port and one for starboard—this kit ensures a totally unobstructed view, allowing the sonar to "look" around your keel or running gear with ease.

Built from marine-grade stainless steel, these transducers are suitable for use on fibreglass, wood, or metal hulls. With Raymarine’s legendary RealVision 3D™ technology built-in, you’ll be able to identify structure and locate fish with lifelike clarity, all while the internal AHRS (Attitude Heading Reference System) keeps your image rock-steady, even in the choppiest British waters.

Raymarine Pack of RV-412 RealVision 3D Stainless Steel Thru Hull TxdsKey Features

• All-in-One Sonar Technology: Features 4-channel Wide Spectrum CHIRP, including DownVision™, SideVision™, high-frequency conical CHIRP for fish targeting, and life-like RealVision 3D™.
• Perfect for V-Hulls: Designed specifically for hulls with a 12° deadrise (suitable for the 6° to 18° range). The offset elements compensate for the hull's angle, ensuring the sonar beams point straight down for accurate readings.
• Split-Pair Design: Includes both Port (RV-412P) and Starboard (RV-412S) transducers. This setup clears the keel or propeller shafts, providing a full 180° side-to-side view with no "blind spots."
• Rugged Stainless Steel Construction: A premium, durable through-hull housing that is ideal for all hull materials, providing long-term reliability in harsh saltwater environments.
• Stabilised Imagery (AHRS): The built-in Attitude Heading Reference System automatically compensates for vessel motion—pitch, roll, and heave—to deliver a stable, distortion-free 3D model.
• Low-Profile Installation: The sleek design reduces drag and cavitation. Best of all, there is no fairing block to cut, making for a much cleaner and simpler installation process.
• Fast-Response Temperature Sensor: Integrated sensor provides quick and highly accurate water temperature readings for finding those all-important thermal breaks.

Raymarine Pack of RV-412 RealVision 3D Stainless Steel Thru Hull Txds FAQs

What exactly is the RV-412, and why is it sold as a pair?

The RV-412 is a "split" transducer system designed specifically for boats with a V-shaped hull. Because a single through-hull transducer often can't "see" past a deep keel or the hull's deadrise, Raymarine provides a port (RV-412P) and a starboard (RV-412S) unit. Together, they give you a full 180° view of the underwater world without any blind spots.

Is my boat’s hull suitable for this stainless steel model?

The RV-412 is incredibly versatile. Being stainless steel, it is the gold standard for GRP (fibreglass), wood, and metal hulls. If you have a metal hull (aluminium or steel), these are essential as they come with a dedicated isolation kit to prevent any nasty galvanic corrosion.

How do I know if I need the RV-412 (12°) or the RV-420 (20°)?

It all comes down to your hull’s deadrise angle.

• • RV-412: Designed for hulls with a deadrise between 6° and 18°. The internal sonar elements are tilted at 12° to compensate for the slope of your hull.
  • If your hull is flatter (0° to 6°), you’d want the RV-400. If it’s steeper (14° to 26°), the RV-420 is the one for you. If you aren't sure how to measure your deadrise, give us a ring at the office and we can talk you through it!

What kind of sonar technology will I get?

This is a 4-channel Wide Spectrum CHIRP system. In plain English, that means you get four distinct views on one screen:

• • RealVision 3D™: See the bottom structure and fish in a 3D space you can rotate.
  • DownVision™: Photo-like clarity of what’s directly beneath you.
  • SideVision™: See up to 91 metres (300ft) to the left and right of the boat.
  • High Frequency CHIRP: Traditional fish targeting for spotting those elusive arches.

Does it help with the motion of the boat in rougher seas?

Yes, brilliantly. These transducers have a built-in AHRS (Attitude and Heading Reference System). This is a solid-state sensor that tracks your boat's movement (pitch, roll, and yaw) and automatically stabilises the sonar image. Even in a swell, your 3D model on the screen remains steady and accurate.

Is it difficult to install? Do I need fairing blocks?

One of the best things about the RV-412 is the low-profile design. Because the "tilt" is built into the internal sensors, the housing sits almost flush against your hull. This means no fairing blocks are required, reducing drag and making it much safer for trailered boats.

Which Raymarine displays are compatible with this pack?

The RV-412 is designed for direct connection to the Axiom RV, Axiom+ RV, and Axiom Pro RVX series. It uses a 25-pin connector. If you are running the newer Axiom 2 Pro RVM series, do check with us—while these work, you may want to look at the "RVM" specific transducers to get the very latest "MAX" performance.

What are the maximum depths I can expect?

In ideal conditions, you’ll see:

• • 3D, DownVision, and SideVision: Up to 183m (600ft).
  • Traditional CHIRP Sonar: Up to 274m (900ft).

Morgan Marine Expert Tip:

When installing, always ensure the transducers are mounted in "clean" water—away from strakes, water intakes, or anything that creates bubbles (turbulence). If you’re unsure about the placement on your specific hull, feel free to send us a photo of your boat out of the water, and we’ll be happy to advise!
