CPT-S CHIRP 0° Bronze Thru-Hull Transducer

The CPT-S 0° Bronze Thru-Hull Transducer is a high-performance sonar sensor designed to deliver high-resolution CHIRP sonar imagery and dependable depth readings at speed. Its low-profile, flush-mount bronze housing installs through the hull with minimal protrusion, eliminating the need for a fairing block and reducing drag. This streamlined design ensures stable depth tracking even when your boat is on plane, and it’s robust enough for trailered boats, allowing worry-free transport and launch.

Equipped with advanced CHIRP technology, the CPT-S transducer emits a single 25° conical beam that covers a broad area beneath your vessel. The wide beam and CHIRP sonar processing enable exceptional target separation and clarity, so fish and bottom structures stand out distinctly. This transducer can reach depths of up to 275 meters (approximately 900 feet), providing reliable performance for deep-water fishing and cruising alike. A built-in fast-response temperature sensor gives you instant water temperature readings – valuable for locating thermal clines or tracking game fish preferences.

Key features and benefits:

• High CHIRP Sonar Performance: The CPT-S delivers a focused, wide-spectrum CHIRP sonar beam that dramatically improves detail and reduces noise compared to standard fishfinders. You’ll see crisp echoes that make it easier to distinguish bait schools from game fish and identify structure on the bottom.
• Bronze Through-Hull Construction: The rugged bronze housing is ideal for permanent through-hull installation on fiberglass or wooden boats. It sits nearly flush with the hull, ensuring minimal turbulence around the sensor and accurate readings at high speeds. Bronze provides excellent durability and, with proper installation, long-term resistance to marine corrosion.
• 0° Tilt for Flat Hulls: This model features a 0° tilted element, making it best suited for hull bottom sections with 0–5° deadrise. On nearly flat hulls, the transducer’s beam points straight down for maximum echo return. (For greater hull angles, Raymarine offers 12° and 20° tilted versions.)
• Easy Installation & Integration: The transducer comes with a 10 m (33 ft) cable for flexible routing to your helm. Its compact, low-profile form simplifies the installation process, requiring only a suitable 51 mm (2”) borehole. Once mounted, connection to your Raymarine sonar unit is plug-and-play.
• Device Compatibility: The CPT-S Bronze transducer is directly compatible with Raymarine’s Element S series chartplotter/fishfinders and Axiom DV (DownVision) displays. It is also the recommended sonar for the high-performance Axiom Pro S and Axiom 2 Pro S units (when used with the optional A80490 adapter cable to fit the 25-pin socket). If your system includes a CP100 sonar module or an MFD with built-in CHIRP sonar, this transducer will connect seamlessly for immediate use.

The Raymarine CPT-S 0° Bronze Thru-Hull Transducer is an excellent choice for anglers and boaters who demand reliable depth tracking and clear fish targeting without the complexity or cost of multi-channel sonar. It’s particularly ideal for smaller powerboats or sailing yachts with relatively flat bottoms, where a thru-hull sensor can outperform a transom-mount at speed. With its combination of ease-of-installation, CHIRP clarity, and durable bronze build, the CPT-S 0° transducer will enhance your on-water experience by providing accurate, high-detail sonar readings on every voyage – from shallow bays to deep offshore waters.
