Raymarine RV-320 RealVision 3D High CHIRP Plastic Thru-Hull Transducer Pair – 20° | Axiom/Axiom Pro | RAY-T70321

RealVision 3D High CHIRP Sonar — Plastic Thru-Hull Transducer Pair, 20°

The Raymarine RV-320 is a pair of plastic thru-hull transducers designed for Raymarine’s RealVision 3D sonar system. Installed port and starboard through the hull, they work together to generate the immersive 3D sonar imagery that RealVision delivers — showing you a detailed, three-dimensional picture of the bottom, structure, and fish targets beneath and around the vessel.

The conical High CHIRP beam pattern provides superior target separation and resolution compared to traditional single-frequency sonar, with the wide conical coverage giving you a broad view of the water column directly below the hull. Plastic construction makes these transducers well suited to fibreglass and composite hulls, with a 20° element offset for hull-deadrise compensation.

The kit includes everything needed for a complete installation: an 8m transducer extension cable, a split transducer Y-cable, and both port and starboard thru-hull transducers.

⚠️ Connection note: This pair connects using the supplied Y-cable and extension cable to the 25-pin RealVision 3D connection on Axiom RV, Axiom Pro RVX, or RVX1000; A80490 is not required. Confirm your display model and connection requirements before ordering.

Best use case: The RV-320 is the right choice for fibreglass and composite hull vessels being fitted with Raymarine RealVision 3D sonar where the 20° element offset suits the planned installation. The plastic construction is the standard choice for fibreglass hulls — it’s lighter, easier to work with, and doesn’t require the same fairing considerations as bronze. The RV-320 has a 20° element offset; the RV-312 has a 12° offset. Select the model according to Raymarine’s guidance for hull deadrise. The conical High CHIRP beam is optimised for the RealVision 3D imaging system — these transducers are not interchangeable with standard single-element CHIRP transducers.

Heads up: If your hull is timber, the bronze versions — RV-212 or RV-220 — are the correct choice. Confirm your display variant and follow Raymarine’s connection guidance; this pair uses the supplied Y-cable and extension cable with the compatible 25-pin RealVision 3D connection. Contact us with your display model if you need help confirming the correct cable configuration.
