The Raymarine RV-220 RealVision 3D Bronze Thru-Hull Transducer Pair Pack delivers 4-channel, Wide Spectrum CHIRP sonar in a rugged cast-bronze through-hull package sized for inboard or outboard vessels. Internal offset built into each transducer accommodates hull deadrise angles from 13° to 20°, eliminating the need for fairing blocks entirely. A built-in AHRS stabilizes imagery through waves, swells, and turns, while one transducer covers port and downward and the other covers starboard and downward — providing a full 180° of underwater coverage even around deep keels or other protrusions. The low-profile, near-flush design creates no meaningful drag or cavitation, making it equally at home on trailered boats.
