Raymarine CPT-S High CHIRP Plastic Thru-Hull Flush Mount Transducer - 12° Angle — Product description

Upgrade your vessel's sonar capabilities with the Raymarine CPT-S High CHIRP plastic thru-hull flush mount transducer, designed specifically for the 12-degree deadrise angle. This compact powerhouse delivers crisp, high-resolution depth readings through advanced CHIRP technology, making it a go-to choice for sailors, cruisers, and small powerboat enthusiasts navigating fiberglass hulls. Unlike traditional sonar, CHIRP sweeps across frequencies centered around 200 kHz, providing superior target separation and clarity even at higher speeds, so you can confidently track bottom structure and fish targets without guesswork.

Standout Features for Reliable On-Water Performance

  • High CHIRP Sonar Precision: Single-element conical beam spans 25 degrees, capturing detailed imagery up to 900 feet deep, ideal for spotting wrecks, reefs, and schools in varied conditions.
  • Flush-Mount Design: Low-profile plastic housing (urethane construction) blends seamlessly with your hull, reducing drag and maintaining a sleek aesthetic while ensuring durability against marine environments.
  • Extended Cable Reach: 33-foot cable offers flexible routing options, simplifying setup on boats of different sizes without signal loss.
  • Speed-Optimized Operation: Maintains accurate depth data at planing speeds, perfect for dynamic boating scenarios where stability matters.
  • Backed by Warranty: Comes with Raymarine's standard limited coverage for peace of mind during your adventures.

Effortless Installation and Broad Compatibility

Installing the CPT-S is straightforward for thru-hull applications on non-cored fiberglass hulls. Position it to match your 12-degree deadrise (optimized for 6-17 degree ranges across models), cut a precise hole, and secure with the included tube housing—no complex fairing blocks needed. It transmits directly through the hull for clean, interference-free readings.

Seamlessly integrates with Raymarine's ecosystem, including Axiom DV multifunction displays and CP100 sonar modules. For Axiom Pro S series, pair with the optional adapter cable to unlock full CHIRP functionality. Whether you're retrofitting an older setup or building new, this transducer slots in effortlessly, enhancing your chartplotter's down-looking prowess without major overhauls.

Why Boaters Trust the CPT-S for Everyday and Extreme Conditions

Engineered for real-world reliability, the CPT-S excels where others falter. Its CHIRP pulse compression cuts through thermoclines and minimizes noise from aerated water, delivering consistent performance from trolling to racing. Boat owners rave about its ability to reveal subtle contours on sandy bottoms or rocky drop-offs, aiding in anchoring, fishing hotspots, and navigation in unfamiliar waters.

Choose this model for hulls with moderate deadrise—think trailerable sailboats or day cruisers—where space and budget align with pro-grade sonar. It's not just depth data; it's actionable intelligence that keeps you ahead of the curve.
