Navico XSONIC R509LH-W Thru-Hull Wide-Beam CHIRP w/Fairing Block

Imagine scanning vast expanses of water beneath your vessel, spotting schools of baitfish drawing in trophy game, and revealing hidden structures with crystal-clear detail—all without missing a beat on your next offshore adventure. The XSONIC R509LH-W thru-hull wide-beam CHIRP transducer transforms your sonar display into a window of unparalleled underwater intelligence, blending cutting-edge broadband technology with a generous coverage footprint that narrow-beam options simply can't match.

Why Wide-Beam CHIRP Changes the Game for Serious Anglers

Traditional transducers often leave gaps in coverage, especially in shallow to mid-depths where fish lurk near the surface or scatter across wide areas. This wide-beam powerhouse sweeps a consistent 25-degree angle across its high-frequency band, doubling the search area under your boat compared to standard high-frequency CHIRP units. The result? Larger, sharper returns on screen, making it easier to distinguish bait from predators, track fish hugging the bottom, and navigate complex seabeds teeming with structure.

Pair it with modern sounder modules, and you'll punch through noise at speed, maintaining accuracy down to impressive depths. Whether you're trolling for pelagics in deep blue water or bottom bouncing over reefs, this transducer delivers the separation and resolution that turns good trips into legendary hauls.

Superior Performance Across Demanding Conditions

• Exceptional Target Separation: Pinpoint individual fish amid tight schools, even in cluttered waters.
• Bottom Composition Insights: Differentiate hard rock from soft mud, spotting fish that blend seamlessly with the seafloor.
• High-Speed Reliability: Holds strong returns while planing or running, ideal for chasing fast-moving species.
• Deep-Water Prowess: Reliable soundings in excess of 3,000 meters, perfect for bluewater explorers.
• Enhanced Upper Water Column Views: Catch surface runners and mid-water suspenders that slip past conventional beams.

Technical Edge for Seamless Integration

Crafted with 25 internal broadband ceramics, an epoxy housing, and a high-performance fairing block, it's built to handle the rigors of saltwater exposure. The dual-band CHIRP operation—low frequencies from 28 to 60 kHz for deep penetration, high from 150 to 250 kHz for fine detail—ensures versatility across hull types like fiberglass, wood, or metal. Suited for vessels up to 40 feet with deadrise angles from 0 to 25 degrees, it includes a fast-response temperature sensor for real-time water data.

Its exclusive identification tech simplifies setup, while the stuffing tube and fairing optimize water flow for minimal turbulence. Anglers retrofitting from similar installations appreciate the straightforward compatibility, keeping downtime minimal.

Real-World Applications: From Reef Hunting to Open Ocean

Picture this: You're drifting over a distant wreck, and the wide beam illuminates not just the structure but the swirling bait balls and lurking predators encircling it. Or, while running the troll lines, constant wide coverage flags opportunistic strikes off to the sides. Saltwater captains rave about its ability to "see through" thermoclines and debris, providing confidence in unfamiliar grounds. For tournament pros, the crisp imaging means faster decisions—mark the fish, deploy the bait, and hook up.

Installation and Maintenance Insights

Thru-hull mounting positions the elements optimally for clean signals, away from hull wakes. Select a spot forward of props and keels, ensuring fairing alignment matches your hull's deadrise for peak performance. Post-install, a simple freshwater rinse after each outing wards off marine growth, preserving acoustic clarity season after season. Regular checks on cable integrity and fairing security keep it performing like new.
