Zestaw 2 sondy przechodzące ze stali nierdzewnej 20° lewa/prawa burta RV-420, bezpośrednie podłączenie do Axiom (2 x 2 m, kabel Y i przedłużacz 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 view 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 transducers are transom-mount transducers, and the RV-300 transducers are plastic through-hull 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 stainless steel transducers offer several advantages. Their design ensures 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° tilt angle. This angle is designed to accommodate hulls with a pronounced deadrise angle, ensuring the sonar beam is vertically oriented toward the seabed for optimal performance, even on non-flat hulls.

Yes, absolutely. With RealVision 3D, DownVision and SideVision imaging, the RV-420 sounders 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 catch success rates.

RealVision 3D technology is an advanced sonar function that creates a three-dimensional representation of the underwater world. 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 of the transducers, even after prolonged exposure to saltwater and harsh weather conditions.

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

No, the RV-420 transducers are designed for direct connection to Raymarine Axiom multifunction displays. This simplifies the electrical installation and eliminates the need for an additional external sounder 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 you to connect both transducers (port and starboard) to a single RealVision port on the Axiom display, simplifying system integration. An 8-meter extension is also provided to facilitate cable routing.

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

The 20° deadrise compensation angle on the RV-420 transducers means they are pre-angled for installation on hulls with a 20° 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 3D visualization by compensating for boat movements (pitch, roll), ensuring an accurate and stable representation of the underwater structure on your Axiom screen.

To choose the ideal location for through-hull transducers, it is important to consider:

A hull area free of turbulence (away from propellers, keels, or other appendages). A spot 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. Sufficient distance from electrical interference sources.

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

AxiomAxiom+Axiom ProAxiom XLAxiom 2 XL

To fully utilize the RV-420 transducers' 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 system performance and coverage are achieved by using both transducers as intended with the supplied Y-cable.
