RVM-400 series stainless steel all-in-one through hull transducer brings the power and clarity of RealVision MAX technology to inboard and outboard powerboats. The RVM-400 series transducers are compatible with the RVM1600 sonar module and Axiom 2 Pro RVM chartplotters

The RVM-400 series transducers feature DownVision™, SideVision™, 600-Watt High CHIRP, and 3D sonar capability. The transducer has a built-in attitude and heading reference system (AHRS) that stabilizes 3D sonar imagery, automatically compensating for vessel motion. The RVM-400 also has a built-in fast-response water temperature sensor for quick, accurate readings.

The RVM-400 series transducers feature a rugged stainless steel through hull body suitable for fiberglass, wood, or metal hulls. The low-profile design slips effortlessly through the water without causing drag or cavitation.

The RVM-400 is a single, all-in-one transducer suitable for boats with a through-hull transducer mounting position with less than 5° hull deadrise.

The RVM-412 is a port and starboard transducer pair designed for boats with 5° to 15° of deadrise. Each transducer element is tilted at 12° to compensate for the hull deadrise.

The RVM-420 is a port and starboard transducer pair designed for boats with 15° to 25° of deadrise. Each transducer element is tilted at 20° to compensate for the hull deadrise.

The RVM-412 and RVM-420 transducer pairs feature titled offset sonar elements inside their surface mount housings. The tilted elements ensure the sonar’s beam patterns are correctly aligned for maximum performance while eliminating the drag and turbulence associated with a fairing-blocked transducer installation. Bundled transducer pairs include a Y-Cable harness that internally joins the two transducers together and an 8-meter transducer extension cable.
