The Raymarine CPT-120 transducer is a bronze through-hull transducer designed for underwater detection. It provides CHIRP DownVision sonar capabilities for near-photographic images of the seabed, traditional CHIRP sonar for fish and seabed detection, as well as water temperature measurement. It comes with a fairing block to optimize performance at different speeds.

The CPT-120 transducer uses CHIRP (Compressed High-Intensity Radiated Pulse) technology for both DownVision sonar and traditional sonar. The CHIRP DownVision provides highly detailed, near-photographic images of underwater structures and fish, while the traditional CHIRP sonar offers reliable fish and bottom detection.

Yes, the Raymarine CPT-120 transducer integrates a temperature sensor that allows measuring and displaying water temperature directly on your compatible multifunction display.

The CPT-120 transducer is made of bronze. This material is selected for its exceptional robustness and durability in marine environments, particularly for through-hull installations on fiberglass or wooden hulls. Bronze resists corrosion and wear well.

The Raymarine CPT-120 transducer comes with a 10-metre cable. This length is designed to simplify installation on various hulls and allow flexible connection to your compatible sounder module or display.

A fairing block is a hydrodynamic unit designed to be mounted around a through-hull transducer. Its purpose is to minimize water turbulence around the transducer, ensuring stable and clear readings from the depth sounder, even when the boat is sailing at higher speeds. It is included with the CPT-120 transducer.

The CPT-120 transducer is specifically designed for CHIRP DownVision and traditional CHIRP sounders. RealVision transducers (such as the RV-100, RV-200, RV-300, RV-400) are more advanced transducers that, in addition to DownVision, offer extended features such as SideVision (side-scanning) and RealVision 3D (three-dimensional seabed imaging).

The CPT-120 transducer provides a maximum detection depth of approximately 183 meters (600 feet) for CHIRP DownVision and up to 270 meters (900 feet) for traditional CHIRP sonar. Actual performance may vary depending on water and seabed conditions.

The CPT-120 transducer is a through-hull bronze transducer, making it particularly suitable for fiberglass and wooden hulls. For aluminum or steel hulls, specific precautions or other types of transducers (such as plastic transducers or internal installations) may be preferable to avoid galvanic corrosion. It is recommended to consult a professional for installation on these materials.

The CPT-120 transducer is compatible with Raymarine multifunction displays in the xx8 series (such as a78, a98, a128, eS78, eS98, eS128, gS98, gS128, gS168) and AXIOM DV displays (such as Axiom 7 DV, Axiom 9 DV, Axiom 12 DV). It can also connect directly to the CP100 sounder module.

The CPT-120 transducer can be directly connected to certain compatible Raymarine multifunction displays that include DownVision electronics (such as the xx8 and AXIOM DV series). Alternatively, it can be connected to the Raymarine CP100 external sounder module if your display does not have a direct DownVision transducer port.

The CPT-120 transducer is specifically designed to work with DownVision technology. If your Raymarine display does not have built-in DownVision capability or is not compatible with the CP100 module, it will not be able to fully utilize the features of this transducer. Always verify the compatibility of your display model.

No, the Raymarine CPT-120 transducer uses a proprietary Raymarine connector and protocol. It is designed to work exclusively with compatible Raymarine equipment, such as the CP100 sounder module or the multifunction displays from the xx8 and AXIOM DV series.

The CPT-120 transducer is compatible with Raymarine display series specified as the xx8 and AXIOM DV, as well as the CP100 module. Older series that do not support CHIRP DownVision technology or lack the appropriate connector will not be compatible with this transducer.

The CPT-120 transducer is a through-hull type. This means it is installed by drilling a hole in the boat's hull, with the transducer body passing through the hull and the transducer face flush with the waterline. The fairing block is then mounted to optimize water flow.

For optimal performance, the CPT-120 transducer must be installed in an area where water flow is as laminar as possible (without air bubbles), typically away from propellers, keels, water intakes, or any other disruptive elements. It must be installed in the direction of the boat's travel and, ideally, where it will remain submerged even at high speed.

Yes, installing the CPT-120 transducer, being a through-hull transducer, requires drilling a hole in your boat's hull. This hole allows the transducer to pass through the hull so that its transmitting and receiving face is in direct contact with the water. Watertightness must be ensured with appropriate marine sealants.

The fairing block is included with the CPT-120 transducer and its use is highly recommended. It is designed to significantly improve the fishfinder's performance, especially at higher cruising speeds, by ensuring smooth and turbulence-free water flow around the transducer face. While technically not "mandatory" for basic operation, it is essential for achieving optimal performance.
