Bronze through-hull transducer pack port and starboard 20° RV-220 RealVision 3D, direct connection to AXIOM (2 x 2m cables, Y-cable and 8m extension)

This RV-220 RealVision 3D transducer kit is specifically designed for direct connection to Raymarine Axiom chartplotters and multifunction displays. It integrates optimally within the LightHouse 4 ecosystem.

The pack includes the following items:

Two 20° tilted bronze through-hull transducers (port and starboard).Two 2 m cables for transducer connections.One Y-cable to combine signals from both transducers.One 8 m extension cable for flexible installation.

These bronze transducers are generally preferred for fiberglass and wooden hulls, offering superior durability in the marine environment. They are specifically suited to hulls with a deadrise angle between 16° and 24°.

Raymarine’s RealVision 3D technology combines DownVision, SideVision, and a three-dimensional view of the seabed. It provides detailed insight into underwater structures and fish positioning, with extended sonar coverage and optimized 3D imaging thanks to port and starboard configuration, reducing shadow zones beneath the boat.

Yes, calibration is required after physical installation of the transducers. The system requires RealVision™ AHRS (Attitude and Heading Reference System) calibration and sonar transducer calibration to ensure optimal data accuracy.

No, it is imperative to test and use depth sounder transducers only when they are submerged in water. Do not operate them out of the water, as this may cause overheating and damage the transducers.

Through-hull bronze transducers offer several advantages:

Increased durability: Bronze is a robust material, ideal for marine environments, especially for fiberglass and wooden hulls.Consistent performance: Thanks to their robust through-hull mounting, they maintain stable and reliable performance even at high speeds.Fewer interferences: Compared to transom-mounted transducers, through-hull transducers are less prone to turbulence and interference, providing better sonar image quality.

The pack includes two 2-metre cables (one for each transducer), a Y-cable to combine them, and an 8-metre extension. This provides an effective total length of approximately 10 metres from each transducer to the Axiom display, offering good flexibility for most installations.
