Raymarine CPT-S High CHIRP Plastic Thru-Hull Flush Mount Transducer - 20° Angle

Discover the precision and reliability of the Raymarine CPT-S High CHIRP Plastic Thru-Hull Flush Mount Transducer, designed specifically for boaters seeking crystal-clear underwater insights without the hassle of complex setups. This 20-degree angled model excels in non-cored fiberglass hulls, delivering high-resolution CHIRP sonar imagery that's perfect for tracking depth changes during sails, leisurely cruises, or powering through waves on smaller vessels. Its innovative flush-mount design hugs the hull's contour, ensuring stable performance even at higher speeds where traditional transducers might falter.

Superior Sonar Performance for Everyday Boating Adventures

What sets the CPT-S apart is its ability to transmit powerful sonar pulses directly through the hull, capturing depths up to 900 feet with a sharp 25-degree conical beam. Centered around 200 kHz, the High CHIRP technology provides exceptional target separation, helping you spot fish, wrecks, or underwater hazards with remarkable clarity. Boaters often rave about how it maintains accuracy during rough conditions, thanks to the robust plastic construction that withstands constant water exposure.

Imagine gliding over shallow reefs or navigating unfamiliar bays— this transducer gives you the confidence to explore further. Unlike bulkier options, its low-profile housing fits seamlessly into hulls with deadrise angles from 15 to 25 degrees, minimizing drag and turbulence for smoother rides.

Effortless Installation and Hull Compatibility

Installing the CPT-S is straightforward for weekend warriors and seasoned skippers alike. The thru-hull flush mount requires precise alignment with your hull's deadrise, but the 20-degree angled element makes it a breeze for boats in that sweet spot. With a generous 33-foot cable, you have plenty of reach to connect to your display unit. No need for specialized tools beyond basics—simply bed it in place with marine sealant, and you're ready to scan.

• Accommodates 15-25 degree deadrise hulls for broad vessel compatibility
• Compact urethane housing resists corrosion and impact
• Depth-only recording keeps your focus on what's below
• Ideal for fiberglass hulls without coring

Seamless Integration with Raymarine Systems

This transducer shines brightest when paired with Raymarine's ecosystem. It connects directly to Axiom DV models for plug-and-play CHIRP operation, and with an optional adapter, it extends to Axiom Pro S series units. Whether you're upgrading an older CP100 sonar module or building a new multifunction display setup, the CPT-S slots in effortlessly, unlocking high-definition sonar overlays on your charts.

Pro tip: For optimal results, calibrate your system post-install to account for hull speed and water conditions. This simple step maximizes beam coverage and minimizes false readings, ensuring every outing delivers actionable data.

Real-World Benefits That Outperform Expectations

Owners appreciate how the CPT-S cuts through noise for reliable high-speed readings, making it a go-to for trailerable boats or day sailors. Its single-element design keeps costs down without sacrificing image quality, and the 25-degree beam strikes a perfect balance—wide enough for general scanning, focused enough for precise targeting. In tests across varied waterways, it consistently outperforms in murky waters where lower-frequency units struggle.
