Bronze through-hull CPT-120 transducer with CHIRP, depth sounder and temperature, direct CP100 connection, xx8 and AXIOM DV screens (10m cable)

The Raymarine CPT-120 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, and 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 the DownVision sounder and the traditional sounder. CHIRP DownVision delivers highly detailed, near-photographic images of underwater structures and fish, while the traditional CHIRP sounder provides reliable fish and bottom detection.

Yes, the Raymarine CPT-120 transducer includes a temperature sensor that measures and displays water temperature directly on compatible multifunction displays.

The CPT-120 transducer is made of bronze. This material is chosen for its robustness and exceptional 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 is supplied with a 10-metre cable. This length is designed to facilitate installation on a variety of hulls and allow flexible connection to your compatible sounder module or display.

A fairing block is a hydrodynamic block 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 fishfinder, 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 depth sounders. The 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 offers a maximum detection depth of approximately 183 metres (600 feet) for CHIRP DownVision and up to 270 metres (900 feet) for traditional CHIRP sounder. Actual performance may vary depending on water and seabed conditions.

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

The CPT-120 transducer is compatible with Raymarine multifunction displays from 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 connected directly 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 fishfinder 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 integrated DownVision capability or is not compatible with the CP100 module, it will not be able to fully utilize the features of this transducer. Always check your display model's compatibility.

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 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 is a through-hull transducer. 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 water outside. The fairing block is then mounted to optimize water flow.

For optimal performance, the CPT-120 transducer must be installed in a location where water flow is as laminar as possible (free of 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 forward motion and, ideally, where it will remain submerged even at high speeds.

Yes, installing the CPT-120 transducer, being a through-hull model, 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 performance of the fishfinder, especially at higher cruising speeds, by ensuring smooth and turbulence-free water flow around the face of the transducer. While technically not "required" for basic operation, it is essential for achieving optimal performance.
