Furuno CA50B-6G Rubber Coated Transducer w/ Fairing Block, 1kW (No Plug)

Upgrade your marine sonar system with the Furuno CA50B-6G, a rugged rubber-coated transducer designed for serious boaters and anglers who demand reliable deep-water performance. This 1kW powerhouse operates at 50 kHz, delivering a wide 28-degree beam angle that scans broad areas efficiently, helping you locate fish schools, wrecks, and underwater structures with pinpoint clarity. The rubber coating adds an extra layer of toughness against impacts and corrosion, while the included fairing block ensures optimal water flow for maximum echo return, even at higher speeds.

Key Advantages for Everyday Boating Adventures

What sets this transducer apart is its blend of durability and precision. The rubber construction flexes slightly under pressure, reducing the risk of cracks from hull vibrations or minor collisions—common issues in rough seas. Paired with the fairing block, it mounts flush to your hull, minimizing drag and turbulence that can muddy your sonar readings. Weighing just 6.6 pounds, it's manageable for most DIY installations, and the 15-meter cable gives you flexibility in routing to your display unit.

Boaters often praise its stability in saltwater environments, where the coating resists marine growth better than bare ceramic elements. Whether you're trolling for bottom dwellers or searching mid-water columns, this unit excels at revealing subtle details like bait balls or thermoclines that generic transducers might miss.

Performance Specs That Deliver Real Results

• Power Output: 1kW for strong signal penetration in depths up to hundreds of feet, ideal for offshore trips.
• Frequency: Primarily 50 kHz for wide-area coverage; bonus compatibility with select 75 kHz settings on advanced Furuno sounders for finer resolution when needed.
• Beam Width: 28 degrees at 50 kHz, striking a balance between sweep and focus.
• Cable: 15 meters of direct-wired cable (no plug included), perfect for custom integrations.
• Mounting: Through-hull with fairing block for hydrodynamic efficiency.

Installation Insights from Seasoned Installers

Mounting the CA50B-6G is straightforward but rewards attention to detail. Position it forward of any prop wash or strakes, dead center on the keel line for balanced readings. The fairing block wedges it at the ideal angle—typically 12-20 degrees depending on your hull deadrise—channeling water smoothly over the face. Use marine sealant around the hull fitting to prevent leaks, and bed the fairing with thickened epoxy for a rock-solid hold.

Pro tip: Test at various speeds post-install to fine-tune the angle. At planing speeds, you'll notice cleaner bottom tracks and fewer dropouts compared to poorly faired setups. It's a favorite for fiberglass and aluminum hulls alike, holding up through seasons of heavy use.

Versatile Applications Across Fishing Styles

From charter captains chasing tuna to weekend warriors targeting stripers, this transducer shines in diverse scenarios. Its wide beam is forgiving for structure scanning near reefs or drop-offs, while the 1kW punch cuts through sediment in bays or rivers. Integrate it with high-end Furuno chartplotters and fishfinders for a seamless network that overlays sonar data on charts, boosting your catch rates without the guesswork.

Maintenance is minimal: Rinse with fresh water after saltwater exposure, and inspect the rubber for wear annually. This longevity means fewer replacements and more time on the water.
