Raymarine HV-300 HyperVision™ T70448 plastic through-hull transducer pack port and starboard 12°

Raymarine's HyperVision™ technology uses ultra-high CHIRP frequencies to deliver underwater images with high clarity and detailed resolution. It enables precise detection of submerged structures, fish schools, and seabed features.

These sounders support DownVision, SideVision, and RealVision 3D imaging modes. These modes provide a complete and detailed view of what lies beneath and around your boat.

The HV-300 HyperVision™ transducers are compatible with Raymarine multifunction displays from the Element and Axiom series.

The HV-300 transducers are through-hull transducers, meaning they are installed directly through the boat’s hull. Unlike transom-mount transducers such as the HV-100, through-hull installation ensures laminar water flow around the transducer, reducing noise and interference, which is critical for maintaining signal quality at higher speeds.

The T70448 pack includes two plastic through-hull transducers: one for port-side installation and one for starboard-side installation.

For installation, it is essential to use only a neutral marine-grade polyurethane sealant. It is critical to NOT use sealants containing acetate or silicone, as they can damage plastic components.

No, you must use only water-based antifouling paint. It is crucial NOT to use ketone-based or copper-based products, as this could affect the product warranty and its performance.

The HV-300 transducers in this kit have a 12° beam angle. They are optimized for boats with a pronounced keel angle (deadrise), ensuring that the side-scanning beams are correctly oriented for optimal coverage.

No. Transducers must only be tested and used when fully submerged in water. Operating them out of the water can cause overheating and damage the transducer.

Through-hull installation of HV-300 transducers directly in the hull ensures laminar water flow around the transducer element. This minimizes noise and interference, which is essential for maintaining high signal quality, even at higher boat speeds.

The HV-300 transducer pack includes port and starboard transducers. However, tools, marine-grade neutral polyurethane sealant, and water-based antifouling paint required for installation are not included and must be purchased separately.

No, the HV-300 HyperVision™ depth sounders are designed to be directly compatible with Raymarine multifunction displays from the Element and Axiom series, which already integrate the required sonar technology. They do not require an additional external sonar module.

Raymarine recommends installation by a certified Raymarine installer. Certified installation provides enhanced product warranty benefits. For further details, contact your Raymarine dealer.

These transducers are through-hull plastic models.

Yes, the pack is designed for port and starboard installation. This combined positioning with each transducer’s 12° angle is essential for optimal coverage and to fully utilize the SideVision and RealVision 3D imaging modes.

Yes, it is crucial to choose a location that ensures laminar water flow around the transducers to minimize noise and interference. The location must also allow the side-scan beams to be properly oriented for optimal coverage, especially on hulls with a pronounced keel angle.

Port and starboard positioning of depth sounders is strategic. Combined with the 12° angle of each transducer, this ensures that the side-scan beams are correctly oriented for optimal coverage beneath and around the boat, especially on hulls with a pronounced keel angle.

To maintain optimal performance of your HV-300 transducers, regular cleaning is required. It is important to follow Raymarine’s specific instructions for transducer cleaning and routine checks to avoid any buildup of dirt that could affect signal quality. Applying water-based antifouling paint is also recommended and should be renewed according to the manufacturer’s guidelines.
