Discover Superior Deep-Water Performance with the Furuno 50kHz FRP Transducer

Navigating the vast expanses of the open ocean demands equipment that delivers clear, reliable signals even at extreme depths. The Furuno CA50BL-12HR FRP transducer rises to this challenge, engineered specifically for marine enthusiasts who prioritize precision in sonar detection. Operating at 50kHz, this powerhouse is your go-to for scanning deeper waters where fish schools gather far below the surface, providing the kind of detailed bottom contours and fish arches that turn a good day on the water into an exceptional one.

What sets this transducer apart is its robust fiberglass-reinforced plastic (FRP) housing, designed to withstand the relentless pounding of saltwater environments without compromising on signal integrity. Whether you're chasing trophy tuna in the bluewater or mapping uncharted reefs, its 2kW power output ensures strong, consistent performance that cuts through thermoclines and sediment layers with ease.

Key Advantages for Serious Anglers and Boaters

• Optimized for Depth: The 50kHz frequency excels in deeper waters, offering minimal signal loss over long ranges compared to higher frequencies—ideal for offshore adventures where every ping counts.
• Wide Coverage Beam: With a 14° x 18.5° directional pattern, it paints a broad picture of the underwater world, helping you spot bait balls and structure without constant repositioning.
• Durable Build: FRP construction resists corrosion, UV damage, and impacts, ensuring longevity in harsh marine conditions. At just 5.5kg and compact dimensions of 120mm x 150mm x 96mm, it's easy to handle during installation.
• Ready-to-Deploy Cable: The included 15m cable gives you flexibility for routing to your display unit, streamlining setup on vessels of various sizes.

Effortless External Installation for Peak Results

Mounting this external transducer is straightforward for DIY-savvy boat owners or professionals alike. Position it on the hull below the waterline, ensuring a smooth, unobstructed path for sound waves—typically forward-facing on the transom or thru-hull for optimal beam spread. The no-connector cable design minimizes potential failure points, letting you focus on the fish rather than fiddly wiring.

Pro tip: Fair the transducer housing to match your hull's deadrise angle for bubble-free operation at speed. This simple step maximizes resolution, reducing noise from aeration and delivering crystal-clear images even at trolling or planing speeds.

Real-World Reliability Backed by Furuno Engineering

Furuno's transducers are trusted by commercial fleets and tournament pros for their unwavering accuracy. Imagine motoring out at dawn, powering up your sounder, and immediately seeing vibrant returns from 1,000 feet down—pelagic species lighting up the screen like holiday lights. The 2kW rating pairs seamlessly with high-end multifunction displays, amplifying weak echoes into actionable intel that informs your lure choice and drift strategy.

Beyond specs, this unit shines in versatility. It's not just for sportfishing; surveyors and researchers appreciate its stable performance for seabed mapping, where precise depth readings inform navigation and safety decisions.

Maintenance Tips to Keep It Performing Like New

1. Clean Regularly: Rinse with fresh water after every outing to flush away salt crystals that could dull the ceramic face.
2. Inspect Connections: Check the cable for wear, especially near high-flex areas, to prevent intermittent signal dropouts.
3. Winter Storage: Dry thoroughly and store in a cool, dry place to avoid moisture-related pitting.
4. Performance Check: Calibrate with your unit's test function annually to confirm peak output.

Investing in this Furuno transducer means fewer false readings, more fish in the box, and confidence in your electronics when it matters most.
