The Raymarine RV-320 Plastic Thru-Hull Transducer Pack brings RealVision 3D™ sonar to inboard and outboard boats via a 4-channel Wide Spectrum CHIRP system that combines DownVision™, SideVision™, high-frequency CHIRP fish targeting, and a built-in AHRS attitude and heading reference system that stabilizes imagery through waves, swells, and maneuvers. Internal offset engineering accommodates hull deadrise angles from 14° to 26°, eliminating the need for fairing blocks entirely, while the low-profile, near-flush design prevents drag and cavitation — making it equally capable on trailered vessels. A pair of plastic thru-hull transducers — one ported, one starboard — each transmit and receive in their respective direction plus downward, delivering a full 180° of underwater coverage even on boats with deep keels or underwater protrusions. A built-in fast-response water temperature sensor rounds out the feature set.
