Pair of plastic through-hull transducers with 12-degree offset

SYLVANIA

SYLVANIA T70320 life jacket

SKU CH-WH6Y-0A3WG MPN T70320

A plastic through-hull transducer pair delivering RealVision 3D sonar with built-in motion stabilization and temperature sensing for deadrise angles up to 12 degrees

  • RealVision 3D sonar gives life-like underwater clarity
  • Built-in AHRS stabilises imagery during vessel motion
  • Pair of transducers covers 1 to 12 degree deadrise without fairing blocks
  • Low-profile design reduces drag and cavitation
  • Fast-response water temperature sensor provides accurate readings

Transducer Pack for 3D Sonar

The Raymarine RV-312 is a plastic through-hull transducer pack designed for inboard or outboard boats. It delivers RealVision 3D sonar, DownVision, SideVision and high-frequency CHIRP fish targeting in a single system. A built-in attitude and heading reference system stabilises imagery by automatically compensating for vessel motion. A fast-response water temperature sensor provides quick, accurate readings.

Check Hull Deadrise and Display Compatibility

The transducers include an internal offset that accommodates hull deadrise angles from 1 to 12 degrees, removing the need for fairing blocks. Verify that your hull angle falls within this range before ordering. You must also confirm that your multifunction display supports RealVision 3D and the four-channel CHIRP signals this pack produces. The pack contains a pair of transducers, so two through-hull openings are required.

Low-Profile Through-Hull Installation

Each transducer mounts flush through the hull for a low-profile fit that reduces drag and cavitation. The plastic housing suits fibreglass or metal hulls when installed with appropriate bedding and fasteners. Two separate holes are needed for the paired units, and cabling must be routed to a compatible Raymarine sonar module or display. The integrated AHRS and temperature sensor require no extra brackets or external probes, freeing space at the transom and simplifying the wiring run.

Questions about this item

What comes in the box with the T70320 and what must be purchased separately?

The pack contains a pair of RealVision 3D transducers with internal offset for 1 to 12 deadrise angles and a fast-response water temperature sensor. A compatible Raymarine multifunction display and cabling are required separately.

Which version of the T70320 should I choose for my hull deadrise?

This single model covers deadrise angles from 1 to 12 degrees using its built-in offset, so no additional fairing blocks or alternative versions are needed.

What does the 312 model number mean for real-world sonar performance?

The RV-312 delivers a 4-channel Wide Spectrum CHIRP system with DownVision, SideVision, high-frequency CHIRP and RealVision 3D, plus an integrated AHRS that stabilises imagery in waves and while manoeuvring.
