Raymarine RV-220 RealVision 3D Pair Bronze Thru Hull 20Deg

The Raymarine RV-220 RealVision 3D Pair Bronze Thru Hull 20Deg transducers represent the gold standard for modern fishfinders and mapping systems, delivering real-time 3D sonar imaging that transforms how anglers and boaters navigate and fish. These bronze thru-hull units are purpose-built for serious water enthusiasts who demand the clarity and precision needed to identify structure, locate schools of fish, and navigate with confidence in both shallow and deep waters. Whether you're working a tournament circuit or exploring unfamiliar coastlines, the RV-220 pair eliminates the guesswork and puts actionable intel directly on your display.

Built from marine-grade bronze, these thru-hull transducers resist corrosion and salt-water degradation far better than plastic alternatives, ensuring years of reliable service in harsh saltwater environments. The 20-degree beam angle provides an optimal balance—wide enough to cover productive bottom terrain yet narrow enough to deliver sharp target definition and excellent depth penetration. RealVision 3D sonar technology generates photorealistic images of submerged objects, vegetation, and bottom composition by combining traditional sonar returns with advanced signal processing. The paired configuration allows simultaneous multi-frequency operation, enabling split-screen viewing of different sonar modes for maximum tactical advantage and faster decision-making on the water.

These transducers are engineered for permanent installation on boats equipped with compatible Raymarine chartplotters and sonar displays, making them ideal for cruisers, center consoles, and dedicated fishing platforms where reliability and integration are non-negotiable. Professional anglers, charter captains, and recreational boaters who have invested in Raymarine ecosystems will appreciate the seamless hardware compatibility and intuitive software integration. Installation requires a qualified marine technician familiar with thru-hull mounting; proper placement and sealing are critical to prevent water intrusion and ensure peak performance. The 15-pound weight reflects heavy-duty construction designed to withstand vibration, pressure, and the demanding conditions of years-long operational service.
