Pack of 2 through-hull Inox 20° port/starboard RVM-420 transducers, direct AXIOM2 and RVM1600 (2 x 2m cables, Y-cable and 8m extension)

The Raymarine RVM-420 pack (reference T70544) is a complete solution including two stainless steel through-hull transducers, specifically designed for hulls with a deadrise angle of 16° to 24°. It integrates RealVision 3D, DownVision, SideVision and high-frequency CHIRP technologies for detailed sonar imaging. This pack is intended for port and starboard installation for optimal coverage.

The Raymarine RVM-420 sounders integrate several advanced sonar technologies for complete underwater visualization:

RealVision 3D: Provides a three-dimensional view of the seabed, structures, and fish.DownVision: Delivers a clear, photographic image of the seabed and structures beneath the boat.SideVision: Allows visualization of structures and fish on the sides of the vessel.High-frequency CHIRP: Enhances target separation and image resolution.

The RVM-420 through-hull sensors are made of stainless steel, ensuring secure mounting and increased durability in a marine environment.

The RVM-420 transducers have a 20° angle. They are specifically designed for boat hulls with a deadrise angle between 16° and 24°. This integrated angle ensures optimal performance without requiring a fairing block.

The T70544 pack includes the following:

Two RVM-420 stainless steel through-hull transducers with a 20° angle. Two 2-meter transducer cables. A Y-cable to connect both transducers to a single input. An 8-meter extension cable.

The RVM-420 transducers are directly compatible with Raymarine AXIOM2 multifunction displays. They are also compatible with other models in the Axiom range, such as AXIOM, AXIOM+, AXIOM Pro, AXIOM XL, and AXIOM 2 XL displays, provided they are equipped with the appropriate RealVision MAX sounder module or have integrated RealVision MAX capability.

Yes, these transducers are designed for direct compatibility with Raymarine RVM1600 fishfinder modules, as well as with AXIOM2 displays that integrate RealVision MAX technology.

The RVM-420 depth sounders are through-hull type. This means they are installed by drilling through the boat's hull so the transducer section is in direct contact with the water, ensuring optimal sonar performance.

Yes, the installation of through-hull RVM-420 transducers requires drilling the hull of the vessel for each transducer. This process is essential for secure mounting and to ensure the transducer is correctly positioned to capture sonar signals.

Yes, antifouling paint can be applied to RVM-420 transducers. It is recommended to follow the specific instructions of the antifouling paint manufacturer and Raymarine for reapplying antifouling to avoid degrading the transducer's performance.

The pack includes two transducers (one for port and one for starboard) to provide improved and more comprehensive SideVision coverage on both sides of the boat. This setup is particularly beneficial for larger vessels or those seeking detailed side imaging over a wider area.

Yes, transducer positioning is critical for optimal performance. It is recommended to install them in an area where water flow is smooth and free of turbulence, away from propellers, keels, water intakes, or other transducers. Specific guidelines are provided in the installation manual for fiberglass cored hulls.

Yes, calibration is required after installation. The RVM-420 transducers require AHRS (Attitude and Heading Reference System) RealVision calibration to ensure 3D image accuracy and general sonar transducer calibration for correct depth and imaging readings.

The RVM-420 transducer pack includes:

Two 2-meter transducer cables. A Y-cable to connect both transducers. An 8-meter extension cable. This provides sufficient combined cable length for many installation setups.

The RVM-420 transducers transmit a full range of sonar data to your compatible Raymarine display, including:

Detailed 3D images of the seabed and structures.DownVision views beneath the boat.SideVision views of the sides of the boat.Precise depth data.Fish detection and identification.

While the installation manual provides the exact list, installing through-hull depth sounders like the RVM-420 typically requires basic hull-work tools, such as:

An electric drill.Hole saws of various sizes for cutting through the hull.Measuring tools.Marine sealants.Appropriate wrenches and screwdrivers for assembly.

Yes, it is strongly recommended to ensure your compatible Raymarine multifunction display (such as the AXIOM2) is running the latest LightHouse software version. Software updates ensure optimal compatibility and access to all RVM-420 transducer features.

The durability of the RVM-420 depth sounders is ensured by their stainless steel construction, a material known for its corrosion resistance and robustness in harsh marine environments. Additionally, their through-hull installation provides a secure and resilient mounting.

To maintain optimal performance of the RVM-420 transducers, regular maintenance is recommended, including:

Routine checks to ensure no damage or obstructions are present.Cleaning the transducer surfaces to remove marine fouling.Reapplying antifouling paint if necessary, following the appropriate guidelines.

Yes, the Y-cable and extension cable supplied in the kit are designed specifically for RealVision fishfinders in the RVM-400 series, including the RVM-420, and for their connection to compatible Raymarine fishfinder modules or multifunction displays. They ensure optimal connectivity and performance.
