Detailed description

Designed for Raymarine CHIRP fishfinder systems, the A80447 CPT-S plastic thru-hull transducer provides a dedicated underwater detection solution. This transducer uses HIGH CHIRP technology for improved target separation and enhanced image clarity, particularly suited for sport fishing and recreational boating. Made of plastic, it is intended for fiberglass or wooden hulls, where thru-hull installation ensures optimal performance by minimizing turbulence. Its 12° conical beam angle is specifically designed to compensate for significant deadrise angles, ensuring the sonar beam remains vertical for accurate readings.

CPT-S Technology and Positioning

Raymarine’s CPT-S series differs from traditional dual-frequency transducers by its single-band CHIRP approach, offering a wider frequency sweep for detailed echo returns. Unlike DownVision or SideVision transducers that provide photographic imaging, the CPT-S focuses on fish identification and bottom structure with fine resolution. It is compatible with Raymarine multifunction displays equipped with integrated CHIRP sonar or external fishfinder modules compatible with CPT-S. While a 0° CPT-S (such as the E70339 or A80446) is ideal for flat hulls, this 12° version is essential for maintaining performance on deep-V hulls. Compliance with standards 2013/53/EU and EN ISO 8846:2017 ensures its reliability in marine environments.

Installation and Maintenance

The A80447 transducer is a thru-hull model, requiring permanent mounting through the hull. This installation method is preferred for high-speed vessels or those requiring uninterrupted sonar readings, as it avoids interference from water turbulence. The 10-meter cable provided offers installation flexibility to reach the processing unit or display. Regular maintenance is simplified by the ability to apply water-based antifouling paint to prevent marine growth buildup, a critical aspect for maintaining long-term transducer performance.

« Technical analysis: Raymarine CPT-S 12° through-hull transducer for V-hulls »

The Raymarine CPT-S plastic through-hull transducer with a 12° angle (A80447) is an essential component for recreational boaters and anglers with a deep-V hull. Choosing a plastic through-hull transducer is appropriate for fiberglass or wooden hulls, where it provides a clean integration and superior hydrodynamic performance compared to a transom-mount transducer, especially at high speeds or in choppy waters. The 12° angle is critical: it compensates for the hull’s deadrise angle, ensuring the sonar beam cone is projected vertically toward the bottom, which is essential for accurate depth readings and reliable fish detection. Without this compensation, the beam would be tilted, distorting depth and fish location data.

This transducer uses HIGH CHIRP technology, positioning it as a high-performance option for fish identification and structure mapping. It differs from DownVision™ or SideVision™ systems by focusing on a traditional bottom view with enhanced resolution. It is important to note that this transducer is designed for Raymarine CPT-S compatible systems, such as certain Dragonfly or Element series, and will not be compatible with newer RealVision 3D systems that require specific transducers. During installation, careful attention must be paid to hull drilling and sealing—a process that, while feasible for a skilled DIYer, requires specific tools and strict adherence to instructions to prevent any water intrusion issues.

Frequently Asked Questions

Need help? Contact us

Which Raymarine devices is this CPT-S transducer compatible with?

This CPT-S plastic through-hull transducer is compatible with Raymarine CHIRP sounder systems. It operates specifically with Raymarine multifunction displays that include CHIRP sonar, or with external sounder modules that are compatible with the CPT-S technology.

Which depth sounder technology is used by the CPT-S model and what are its specific features?

The CPT-S model uses HIGH CHIRP single-band technology. Unlike DownVision or SideVision transducers that provide photographic imaging, the CPT-S focuses on fish identification and seabed structure with fine resolution and improved target separation. It offers a wider frequency sweep for detailed echo returns.

On which type of hull can this plastic through-hull transducer be installed?

This plastic through-hull transducer is designed for installation on fiberglass or wooden hulls. Its through-hull (thru-hull) installation requires permanent mounting through the hull.

What are the advantages of a through-hull transducer installation?

Through-hull installation is preferred for high-speed boats or those requiring uninterrupted sonar readings. This mounting method ensures optimal performance by minimizing turbulence and interference, providing accurate and reliable sonar data even at high speeds.

What is the length of the cable supplied with this Raymarine CPT-S transducer?

The Raymarine CPT-S through-hull plastic transducer (part number A80447) is supplied with a 10-metre cable.

What is the beam angle of this transducer and what is its purpose?

This transducer has a 20° conical beam angle. This angle is specifically designed to compensate for the high deadrise angles of boats, ensuring the sonar beam remains vertical for accurate readings of the seabed and underwater targets.

How should I maintain and clean my depth sounder to preserve its performance?

To maintain your depth sounder's performance, clean it regularly. Use a soft cloth and mild household detergent. For heavy fouling, a non-abrasive cleaning pad may be used, taking care not to scratch the transducer face. To prevent marine growth buildup, apply a thin coat of water-based antifouling paint to the transducer. Never use ketone-based solvents, as they can damage the sensor, nor spray paint containing air bubbles.

Is it recommended to have this transducer installed by a professional?

Yes, Raymarine recommends certified installation performed by an authorized installer. Professional installation ensures the product is installed and used in accordance with the instructions, which is essential for optimal product performance and the safety of your vessel.
