Raymarine CPT-S High CHIRP Bronze Thru-Hull Flush Mount Transducer - 0° Angle

Upgrade your boating experience with the Raymarine CPT-S High CHIRP Bronze Thru-Hull Flush Mount Transducer, engineered for boaters who demand precise depth readings without the hassle of complex setups. This compact powerhouse delivers crystal-clear sonar images through advanced CHIRP technology, making it a go-to choice for sailors, cruisers, and powerboat enthusiasts navigating diverse waters. Mounted flush on hulls with minimal deadrise, it cuts through the hull cleanly, ensuring reliable performance even at higher speeds where traditional transducers might falter.

Why Choose a Bronze Thru-Hull Transducer for Your Vessel

Bronze construction stands out in marine environments for its superior corrosion resistance, especially in saltwater conditions that eat away at lesser materials. Unlike plastic alternatives, this transducer maintains integrity over seasons of heavy use, providing consistent high-frequency signals centered around 200 kHz. The flush-mount design minimizes drag, preserving your boat's hydrodynamics while capturing depths up to 900 feet with a focused 25-degree conical beam. Boat owners rave about its ability to separate fish targets from bottom clutter, turning casual outings into productive fishing trips or safe passages through unfamiliar shallows.

Seamless Installation for Hands-On Boaters

Installing the CPT-S is straightforward for those comfortable with basic marine DIY. Select a smooth, flat hull section matching the 0-degree tilt, drill a precise hole, and bed the bronze housing with marine sealant for a watertight seal. No need for fairing blocks on flat-bottomed hulls, and its low-profile shape hugs the hull contour. With a generous cable run, routing to your display unit is flexible—pair it directly with compatible multifunction displays for plug-and-play convenience. Pro tip: Time your install during a haul-out to avoid dry-docking later, and always double-check hull thickness to optimize signal transmission.

Superior CHIRP Performance in Real-World Conditions

CHIRP sonar revolutionizes underwater detection by sweeping across a broad frequency band, delivering sharper images than fixed-frequency systems. On the water, this translates to spotting structure, wrecks, and schools amid thermoclines or murky bottoms. Sailors appreciate its stability during heel, while powerboaters trust it for high-speed bottom tracking. Expect enhanced target resolution that helps distinguish baitfish from keepers, all without the noise interference common in rough seas. It's not just a depth finder—it's your edge for safer, smarter navigation.

Compatibility and Expandability

Designed for seamless integration into Raymarine ecosystems, this transducer shines with dedicated sonar modules and all-in-one chartplotters. It supports direct connections for quick setups, and with simple adapters, extends to advanced RV series units. Whether retrofitting an older helm or building a new suite, it future-proofs your electronics investment. Boaters often pair it with GPS overlays for contour mapping, turning raw depth data into actionable insights for route planning or anchoring spots.

Long-Term Reliability and Care Tips

Crafted for durability, the CPT-S withstands the rigors of coastal cruising and offshore adventures. Routine checks—like inspecting the face for marine growth and securing cable ties—keep it performing like new. In freshwater, it excels too, but bronze's saltwater prowess makes it ideal for serious bluewater use. Owners report years of trouble-free service, underscoring its value in any serious boating toolkit.
