Raymarine’s RV-400 stainless steel through hull transducer is designed for inboard and outboard powerboats. It lets you easily identify structures and locate fish with the life-like clarity of RealVision 3D™ sonar. Compatible with Axiom MFDs with RV, RVX and RVM.

The RV-400 is a 4-channel, Wide Spectrum CHIRP transducer with DownVision™, SideVision™, conical CHIRP fish targeting and RealVision 3D™ sonar inside. The transducer has a built-in attitude and heading reference system (AHRS) that stabilizes 3D sonar imagery, automatically compensating for vessel motion. You’ll enjoy an accurate and life-like model of the underwater environment that filters out distortions caused by waves, swells, or vessel maneuvering. A water temperature sensor is also built-in.

Rugged stainless steel body suitable for fiberglass, timber, steel or aluminium hulls. The low-profile design slips through the water without causing drag or cavitation. The near-flush RV-300 works even works great on trailered boats, and with no fairing block to cut, installation is a breeze.
