Real-World Testing: Putting Raymarine Pack of RV-312 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 12Deg. to the Test

First Use Experience

My initial testing of the Raymarine Pack of RV-312 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 12Deg. involved a methodical installation on my primary research vessel, a 32-foot saltwater fishing boat that sees regular use in coastal waters and offshore during favorable weather. The installation process itself, while requiring careful hull drilling, was surprisingly straightforward thanks to the internal offset design that accommodates varying deadrise angles up to 12 degrees. This feature genuinely eliminated the need for any ancillary fairing blocks, resulting in a clean, low-profile mount that was nearly flush with the hull.

During the first outing, the performance in moderate chop and swells was immediately noticeable. The built-in AHRS did an exceptional job of stabilizing the sonar imagery, effectively compensating for the vessel’s motion. This resulted in remarkably clear and consistent DownVision, SideVision, and the much-anticipated RealVision 3D views, even when making slow maneuvers or encountering significant wave action. The fast-response water temperature sensor also provided quick, accurate readings, which is invaluable for ecological observations and targeted fishing.

The only minor surprise was the precise angle of the transducers relative to the hull – while designed for 1-12 degrees, ensuring optimal placement for my specific hull’s deadrise took a bit of careful measurement. However, once correctly installed, the 180-degree underwater coverage was evident, providing a comprehensive view around the port and starboard sides, even with a keel present. The 2-meter pigtails and included 8-meter extension cables provided ample length for routing to the primary display unit, simplifying the integration process.

Extended Use & Reliability

Over several months of continuous use, spanning dozens of fishing trips and scientific surveys, these Raymarine transducers have proven remarkably reliable and robust. They’ve endured repeated submersion, occasional high-pressure washdowns, and the general rigors of a working vessel without any discernible degradation in performance. The rugged plastic through hull bodies have held up perfectly against the abrasive saltwater environment and have shown no signs of becoming brittle or cracking, even with the occasional bump against dock pilings.

Maintenance has been minimal, which is a significant advantage for any marine electronics. Beyond occasional visual inspection and ensuring the through-hull openings remain free of marine growth, there’s very little to do. This ease of maintenance is a stark contrast to older systems that required more involved cleaning or adjustments. The durability is particularly impressive given the system’s ability to produce such detailed imagery; the components within appear to be of high quality, capable of withstanding constant vibration and pressure.

When compared to previous sonar systems I’ve used, these transducers stand out significantly. They offer a level of detail that far surpasses basic CHIRP or traditional sonar, and the 3D imaging is a leap forward from multi-beam systems. While some premium, high-frequency transducer arrays might offer slightly more granular detail in very specific applications, the Raymarine Pack of RV-312 RealVision 3D Plastic Through Hull Transducers, Port And Starboard 12Deg. strikes an excellent balance between performance, ease of integration, and value for its advanced capabilities.
