Breaking Down the Features of Raymarine Pack of RV-320 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 20Deg.
Specifications
This pack includes a pair of plastic through-hull transducers, specifically designed for boats with a moderate hull deadrise angle, accommodating anything from 13 to 20 degrees. This design is a significant advantage as it eliminates the need for bulky and often problematic fairing blocks, contributing to a clean hull and reduced drag. Each transducer boasts a low-profile design, further minimizing any potential water resistance or cavitation issues. The system is a 4-channel, Wide Spectrum CHIRP transducer system, which is the foundation for its impressive sonar capabilities.
Inside each transducer are the core components: RealVision 3D sonar, DownVision, SideVision, and high frequency CHIRP fish targeting. The inclusion of a built-in attitude and heading reference system (AHRS) is a critical specification, as it actively stabilizes the sonar imagery by compensating for the vessel’s pitch, roll, and yaw. This stabilization is paramount for clear and accurate readings, especially in challenging sea states or during boat maneuvers. Additionally, a built-in fast response water temperature sensor provides immediate and precise temperature data. Each unit comes with a 2-meter pigtail, joining with a y-cable, and an 8-meter extension cable, providing a generous overall cable length of 10 meters (33 feet), which is ample for most inboard or outboard boat installations.
Performance & Functionality
The primary job of these transducers is to paint a clear picture of the underwater world, and they excel at this. The RealVision 3D sonar provides an almost three-dimensional view of structure, bait, and the seabed, making it incredibly easy to interpret. DownVision offers a photorealistic view directly beneath the boat, ideal for identifying baitfish, bottom structure, and potential fishing hotspots. Similarly, the SideVision capability extends the sonar’s view to approximately 180 degrees out to the sides of the vessel, revealing hidden structures or fish that might otherwise be missed.
The Raymarine Pack of RV-320 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 20Deg. absolutely meets and exceeds expectations for its intended use. Its strengths lie in the unparalleled clarity and detail of the sonar imagery, the excellent stabilization provided by the AHRS, and the ease of installation due to the through-hull design. A minor point of consideration, rather than a weakness, is that the 20-degree beam angle is optimized for certain hull types; on extremely flat or extremely deep-V hulls, users might need to consider different transducer options for optimal coverage. However, for hulls within the specified deadrise range, it performs admirably.
Design & Ergonomics
The design of the RV-320 system is focused on practicality and performance in the marine environment. The rugged plastic through hull bodies are suitable for fiberglass, steel, or aluminum hulls, offering versatility. Their low-profile design is a significant ergonomic win, slipping through the water with minimal disruption, which translates directly to better performance and fuel efficiency. The near-flush mounting is also a boon for trailered boats, reducing the risk of damage during transport.
The integration of the AHRS within the transducer itself simplifies the overall installation, as there’s no need for a separate heading sensor unit. This streamlined approach contributes to a cleaner installation and fewer potential points of failure. The included cabling is robust and well-terminated, ensuring a secure connection. While the plastic construction might feel less substantial than a metal transducer to some, the real-world performance and durability have proven it to be a well-engineered choice for its intended application.
Durability & Maintenance
Raymarine has designed these transducers with longevity in mind, and after extended use, this appears to be the case. The plastic through hull bodies are resistant to corrosion and the harsh marine environment. I anticipate these units will last many seasons with minimal concern for wear and tear, provided they are installed correctly.
Maintenance is refreshingly simple. Regular rinsing with fresh water after use in saltwater is the primary requirement. There are no complex internal parts to clean or service externally. The sealed nature of the unit, being a through-hull design, means that internal components are protected from the elements. Potential failure points would likely stem from improper installation (e.g., poor sealing leading to water ingress) or physical impact, rather than inherent material fatigue. The internal offset for hull deadrise is a fixed feature, meaning it’s not adjustable, but it is designed to accommodate a specific range effectively.
Accessories and Customization Options
The Raymarine Pack of RV-320 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 20Deg. primarily consists of the two transducers themselves, along with all necessary cabling to connect them to a compatible Raymarine display unit. This includes the joining y-cable and the 8-meter extension cables. There are no additional physical accessories that come packaged with the transducers themselves, as their functionality is entirely integrated.
Customization is limited to the selection of the appropriate RV-320 model for your specific hull deadrise angle. Once installed, the transducers are not adjustable in terms of their beam angle or other core sonar parameters; these are dictated by the internal design and the connected MFD’s software. Compatibility with other brands of fishfinders or sonar units is generally not possible, as these transducers are proprietary to Raymarine systems. The value here is in the integrated system and the tailored performance they offer within the Raymarine ecosystem.
