Designed for inboard and outboard powerboats. The RV-200 lets you easily identify structures and locate fish with the life-like clarity of RealVision 3D™ sonar. A 4-channel, Wide Spectrum CHIRP transducer with DownVision™, SideVision™, high frequency CHIRP fish targeting and RealVision 3D™ sonar inside. The transducer has a built-in attitude and heading reference system (AHRS) that stabilizes the sonar imagery, automatically compensating for vessel motion. You'll enjoy crystal-clear imagery in waves, swells, and while maneuvering. The RV-200 also has a built-in fast response water temperature sensor for quick, accurate readings. Features a rugged cast-bronze through hull body suitable for fiberglass or wooden hulls. The RealVision 3D™ transducer elements are arranged with a 0° offset for boats with flat bottoms. The low-profile design slips effortlessly through the water without causing drag or cavitation. The near-flush RV-200 works great on trailered boats too, and with no fairing block to cut, installation is a breeze.
