Furuno Rubber Coated Transducer - 5kW

Imagine scanning the ocean floor at extreme depths, spotting massive schools of tuna or wrecks hidden in the abyss, all with crystal-clear returns that cut through thermoclines like a hot knife. That's the everyday reality for serious offshore anglers and commercial operators using the Furuno CA28F-38M rubber-coated transducer. This powerhouse isn't just gear—it's your edge in the deep blue, delivering reliable performance where lesser units falter.

Built for vessels pushing limits, its low 28kHz frequency punches through water columns up to thousands of feet, revealing structure and fish that higher frequencies miss. The rugged rubber housing shrugs off impacts, corrosion, and harsh marine environments, making it a go-to for working boats and weekend warriors alike.

Unlock Superior Deep-Water Detection

The magic lies in that 14-degree beam width. At shallow ranges, it paints a broad picture of the bottom; drop deeper, and it maintains exceptional target resolution without the narrow tunnel vision of tighter beams. Paired with 5kW of raw power, echoes bounce back stronger and sharper, even in rough seas or heavy clutter.

• Deep Penetration: 28kHz excels in saltwater, ignoring surface noise and biomass interference common in productive fishing grounds.
• Wide Coverage: Spot schools spreading across vast areas without constant repositioning.
• High Resolution: Distinguish bait balls from big game fish with ease.

Recreational skippers love it for tournament fishing, while pros rely on it for trawling ops—versatile enough for monohulls, catamarans, or even larger commercial hulls.

Effortless Installation for Real-World Use

No hull drilling required. Chest or tank mounting keeps your vessel's integrity intact, ideal for aluminum or fiberglass hulls where thru-hull penetrations aren't feasible. Bolt it securely in a dedicated tank for protected, vibration-free operation, or chest-mount forward for optimal water flow.

Pro tip: Position it ahead of props and keels to minimize air entrainment. The 49-foot bare-wire cable gives flexibility for routing to your Furuno sounder, and since it's connectorless, customize terminations to match your setup perfectly.

Built to Withstand the Elements

Weighing in at 44 pounds, this beast demands respect but rewards with unmatched toughness. The rubber coating acts as a shock absorber against groundings or dock bumps, while sealing out moisture for years of service. Expect seamless integration with Furuno's DRS series or TZtouch systems, amplifying your chartplotter's sonar capabilities.

Maintenance is straightforward: Periodic hull cleaning prevents marine growth from dulling performance. Rinse after saltwater exposure, and you're set. Backed by a solid warranty, it's engineered for longevity in demanding conditions.
