Raymarine's RV-100 all-in-one transom mount transducer easily identifies structures and locates fish with the life-like clarity of RealVision 3D sonar. The RV-100 is a 4-channel, Wide Spectrum CHIRP transducer that features DownVision™, SideVision™, high-frequency CHIRP fish targeting, and RealVision™ 3D sonar. The transducer incorporates an AHRS (Attitude and Heading Reference System) that stabilizes the 3D sonar imagery, automatically compensating for vessel motion. You'll enjoy a precise, lifelike model of the underwater environment that filters out distortions caused by waves, swell, or vessel maneuvers. The RV-100 also features a high-precision water temperature sensor for fast, accurate readings.
