Pack 2 sondes travesseres d’acer 20° babord / estribord RV-420, connexió directa Axiom (2 x 2 m, cable Y i extensió 8 m)

The Raymarine RV-420 pack includes:

Two RV-420 stainless steel through-hull transducers (one port and one starboard). Two 2-metre transducer cables each. A Y-cable for connecting both transducers. An 8-metre cable extension.

The Raymarine RV-420 transducers are designed to provide detailed sonar imaging of the underwater world. They allow users to visualize the seabed structure, fish, and relief in real time using RealVision 3D, DownVision, and SideVision technologies.

The main difference lies in their design and material. The RV-420 transducers are through-hull stainless steel transducers, offering superior robustness and hydrodynamic performance. The RV-100 are transom-mount transducers, and the RV-300 are through-hull plastic transducers. The RV-420 pack also provides extended coverage thanks to its dual configuration (port/starboard).

The RV-420 transducers integrate RealVision 3D technology and provide access to the following sonar imaging functions:

RealVision 3D: For a three-dimensional representation of the seabed, structures, and fish.DownVision: For a detailed view beneath the boat.SideVision: For a side view of structures and fish on either side of the boat.

Through-hull transducers in stainless steel offer several advantages. Their design ensures a robust installation and excellent hydrodynamic performance, which is crucial for stable sonar readings at various speeds. Stainless steel also guarantees superior durability and increased resistance to harsh marine environments compared to plastic versions.

Each transducer in the RV-420 pack is equipped with a 20° compensation angle. This angle is designed to adapt to boat hulls with a pronounced incline (deadrise angle), ensuring the sonar beam is vertically oriented toward the bottom for optimal performance, even on non-flat hulls.

Yes, absolutely. With RealVision 3D, DownVision, and SideVision imaging, the RV-420 transducers are highly effective for fishing. They allow precise location of fish schools, identification of underwater structures (rocks, wrecks) where fish hide, and understanding of the seabed relief, improving your chances of success.

RealVision 3D is an advanced sonar function that generates a three-dimensional representation of the underwater environment. It uses multiple transducers to scan a wide area, then combines this data to display a detailed, real-time image of the seabed structure, submerged objects, and fish, providing an immersive and intuitive perspective.

Through-hull stainless steel transducers are renowned for their high durability. Stainless steel is a corrosion-resistant material in marine environments, ensuring long service life and reliable performance even after prolonged exposure to saltwater and weather conditions.

Yes, the RV-420 pack comes with the necessary wiring for a complete installation. It includes two 2-metre cables for each transducer, a Y-cable to connect both transducers to the display, and an 8-metre extension cable, providing flexibility for cable routing.

No, the RV-420 transducers are designed for direct connection to Raymarine Axiom multifunction displays. This simplifies electrical installation and eliminates the need for an additional external fishfinder module, as the RealVision 3D technology is integrated into compatible Axiom displays.

The connection is made directly to Axiom displays via the included Y-cable. This cable allows both transducers (port and starboard) to be connected to a single RealVision port on the Axiom display, simplifying system integration. An 8-meter extension is also provided to facilitate cable routing.

Yes, as these are through-hull transducers, installation requires drilling holes in the boat's hull to permanently secure the transducers. It is recommended to carefully follow the provided installation instructions to ensure perfect watertightness and optimal performance.

The 20° compensation angle on the RV-420 transducers means they are pre-angled for installation on hulls with a 20-degree deadrise angle. This ensures the sonar beam is projected vertically toward the seabed, even if the hull is not flat, optimizing sonar image quality.

Yes, after installation, an AHRS (Attitude Heading Reference System) calibration is required. This calibration stabilizes the 3D visualization by compensating for boat movements (pitch, roll), ensuring an accurate and stable representation of the underwater structure on your Axiom display.

To choose the ideal location for through-hull transducers, consider the following:

A hull area free of turbulence (away from propellers, keels, or other appendages).A location where the hull has an appropriate deadrise angle for the 20° compensation angle of the transducers.Easy access to the inside of the hull for installation and cable routing.A sufficient distance from sources of electrical interference.

The RV-420 transducers are designed for direct connection and are compatible with Raymarine multifunction displays in the Axiom series, including the following models:

AxiomAxiom+Axiom ProAxiom XLAxiom 2 XL

To fully benefit from the RV-420 sounders' features, Axiom multifunction displays must run LightHouse 4 software, version v4.10.149 or later. It is recommended to always keep your software up to date for optimal performance.

The RV-420 transducers are specifically designed for direct connection and optimized integration with Raymarine Axiom series multifunction displays. Compatibility with older Raymarine displays or other brands is not stated and cannot be guaranteed without specific adapters or external modules not included in this kit.

The RV-420 pack is designed as a dual system (port/starboard) to provide extended and optimized coverage of RealVision 3D, DownVision, and SideVision technologies. While it is technically possible to connect only one transducer, full performance and coverage of the system are achieved by using both transducers as intended with the supplied Y-cable.
