Detailed description

Designed for advanced Raymarine fishfinder systems, the plastic through-hull portside 12° HV-300 HyperVision depth sounder, part number R70725, provides an underwater detection solution for planing-hull vessels. This depth sounder uses Raymarine’s HyperVision™ technology, enabling detailed imaging of the seabed and underwater structures. It is specifically designed for installation on the port side of the vessel, with a 12° correction angle to compensate for hull deadrise.

Positioning and HyperVision™ technology

The HV-300 HyperVision depth sounder differs from transom-mounted models like the HV-100 by its through-hull installation, which ensures optimal performance at high speeds and minimal exposure to turbulence. Model R70725 is the portside version (HV-300THP-P), complementing the starboard version (HV-300THP-S, R70726), offering installation flexibility to adapt to hull configurations and avoid interference with appendages or propellers. HyperVision™ technology integrates DownVision, SideVision, and RealVision functions, delivering high-clarity sonar images for fish and structure identification. This product complies with EMC Directive 2014/30/EU.

Installation and maintenance recommendations

Installing the HV-300 depth sounder requires the use of marine-grade neutral-cure polyurethane sealant, excluding acetate- or silicone-based sealants to prevent damage to plastic components. For maintenance, applying a water-based antifouling paint is recommended, avoiding ketone- or copper-based paints that could affect performance or warranty. It is essential to test and use the depth sounder only when the vessel is in the water to prevent overheating. Installation by a Raymarine-certified professional is recommended to qualify for extended product warranty.

« Technical analysis of the Raymarine HV-300 starboard-through-hull transducer at 12° »

The Raymarine HV-300 HyperVision through-hull transducer with a 12° port-side offset (R70725) is a technically sound choice for owners of planing-hull vessels where the deadrise at the chosen location is between 8 and 16 degrees. Unlike the transom-mounted HV-100 series, this through-hull configuration reduces drag and ensures laminar flow around the transducer element, which is critical for maintaining HyperVision sonar image quality at higher speeds. Port-side mounting is often preferred on monohulls or catamarans to avoid disturbances generated by the main propeller or other hull appendages.

Installing this type of transducer requires significant expertise, including hull fairing, drilling, and flawless waterproofing. A fairing block may be necessary to optimize angle and performance if the actual deadrise deviates slightly from the built-in 12°. It is essential to strictly follow Raymarine’s recommendations regarding sealants (neutral polyurethane) and antifouling (water-based) to ensure installation longevity and warranty validity. Poor transducer placement can cause turbulence, degrading sonar returns—especially in SideVision mode. For high-deadrise hulls or specific applications, consider whether a model with a different offset angle or a custom fairing block would be more suitable.

Frequently Asked Questions

Need help? Contact us

What is the HV-300 HyperVision through-hull transducer from Raymarine?

The HV-300 HyperVision is a plastic through-hull transducer designed for installation on the port side of the vessel, with a 12° angle correction to compensate for hull deadrise. It uses Raymarine's HyperVision™ technology, which integrates DownVision, SideVision, and RealVision functions, providing detailed imaging of the seabed and underwater structures. This installation type ensures optimal performance at high speeds with minimal exposure to turbulence.

Which type of sealant should I use to install the HV-300 transducer?

For the installation of the HV-300 transducer, you must use only a neutral-cure marine-grade polyurethane sealant. It is essential not to use sealants containing acetate or silicone, as they could damage the plastic components of the transducer.

Can I apply any antifouling paint to the HV-300 transducer?

No, you cannot use any antifouling paint. It is recommended to apply only water-based antifouling paint on the HV-300 transducer. Avoid ketone-based or copper-based paints, as they may affect the transducer's performance or void the warranty.

Is it possible to test or use the HV-300 transducer out of the water?

No, the HV-300 transducer must be tested and used only when the vessel is in the water. Operating the transducer out of the water may cause overheating and damage the device.

What is the difference between the HV-300 and HV-100 depth sounders?

The main difference lies in their installation method:

The HV-300 is a thru-hull depth sounder, designed to be installed through the hull of the vessel. This installation provides optimal performance at high speed and minimal exposure to turbulence.The HV-100 is a transom-mount depth sounder, designed to be attached to the transom of the vessel.Both depth sounders use HyperVision™ sonar imaging technology.

Which Raymarine multifunction displays are compatible with the HV-300 HyperVision transducer?

The HV-300 HyperVision transducer is primarily compatible with Raymarine Element HV series multifunction displays. These displays are designed to fully leverage HyperVision™ technology and provide detailed sonar images.

What does "port 12°" mean in the HV-300 depth sounder designation?

The designation "port 12°" indicates two important features:

Port: The depth sounder is specifically designed to be installed on the left side of the vessel (port side).12°: The depth sounder includes a 12° correction angle to compensate for the deadrise angle (the V-shape) of the boat's hull. This ensures the fishfinder's beam is directed vertically toward the seabed, providing accurate and optimal readings.

What are the recommendations for choosing the installation location of the HV-300 through-hull transducer?

To ensure optimal performance of the HV-300 transducer, it is essential to select an appropriate installation location. Key recommendations include:

Choose a location where the water flow is smooth and undisturbed by hull appendages (propellers, keels, strakes, etc.). Avoid areas prone to turbulence or air bubbles, which can degrade sonar signal quality. Ensure the location is away from any source of electrical interference. The installation site must be accessible for mounting, maintenance, and cleaning of the transducer.
