Detailed description

Designed for precise underwater detection, the Raymarine CPT-S HIGH CHIRP sounder (reference E70342) is a plastic hull-mounted transducer. It uses wide-spectrum CHIRP technology to deliver improved resolution and target separation compared to traditional fixed-frequency sounders.

Cone-beam integration and performance

The CPT-S sounder is specifically designed to integrate with compatible Raymarine multifunction displays. Its HIGH CHIRP cone beam covers a wider area beneath the boat and provides detailed rendering of the seabed and structures, making fish identification easier. The 10-metre cable offers installation flexibility for most recreational boat setups.

Position in the Raymarine range

Within the Raymarine range, the CPT-S is an accessible CHIRP hull-mounted sounder option, ideal for users seeking CHIRP benefits without the complexity of a more expensive through-hull transducer. It stands out from traditional sounders by its ability to discriminate targets with greater clarity. For applications requiring deeper detection or SideVision/DownVision features, other transducers such as the CPT-DVS or RV-XXX series are available, offering additional multi-element capabilities.

« CPT-S HIGH CHIRP Fishfinder: Analysis and Applications »

The Raymarine CPT-S HIGH CHIRP transducer is a relevant option for recreational boaters and anglers looking to enhance their detection capabilities without the complexity of a through-hull installation. Its transom-mount design makes it a practical solution for quick installation, particularly on small to medium-sized polyester or aluminum hulls. The main advantage of this model lies in its conical CHIRP technology, which provides superior target discrimination compared to single-frequency transducers. This results in better identification of fish schools and clearer visualization of the seabed structure. We recommend this transducer for coastal fishing and general navigation applications where depths rarely exceed 150–200 meters. For more demanding environments or needs for lateral or downward-looking visualization (DownVision/SideVision), Raymarine’s RealVision transducer series should be considered.

Frequently Asked Questions

Need help? Contact us

What is CHIRP cone technology and what are its advantages?

The CPT-S transducer uses HIGH CHIRP cone-beam technology. CHIRP (Compressed High-Intensity Radiated Pulse) with a wide spectrum emits a frequency sweep rather than a single frequency, providing far better resolution and target separation than traditional transducers. The cone beam, in turn, offers broader coverage beneath the boat, delivering a detailed rendering of the seabed and easier identification of fish over a wider area.

Which Raymarine devices is this transducer compatible with?

This CPT-S transducer is specifically designed to integrate with Raymarine multifunction displays compatible with CHIRP conical technology. It is generally compatible with the Element series and certain Raymarine Axiom models, potentially with an adapter depending on the exact display model.

What type of installation does this transducer require?

This is a transom-mount transducer, also known as a 'transom mount'. It is designed to be installed on the outside of your boat's transom, providing a relatively simple and accessible installation.

What is the length of this transducer's cable?

The Raymarine CPT-S transducer comes with a 10-meter cable. This length provides good flexibility for installation on most recreational boats.

What is the difference between this CPT-S transducer and the CPT-DVS or RV-XXX transducers from Raymarine?

The CPT-S transducer uses a HIGH CHIRP conical beam for precise bottom and fish detection. The CPT-DVS (DownVision) and RV-XXX (RealVision 3D, DownVision, SideVision) transducers are more advanced and offer additional structural imaging capabilities. The CPT-DVS adds DownVision technology for near-photographic images beneath the boat, while the RV-XXX also includes SideVision for a lateral view and RealVision 3D for a three-dimensional representation.

What material is this depth sounder made of?

This depth sounder is made of plastic. This material is commonly used for through-hull transducers due to its durability and resistance to the marine environment.

For which type of use is this transducer best suited?

The CPT-S HIGH CHIRP transducer is ideal for recreational boaters and anglers seeking reliable and precise detection of fish and underwater structures. With its conical CHIRP technology, it excels in target discrimination and detailed seabed mapping, making it perfect for sport fishing and general pleasure boating.

Where to install the depth sounder on the transom for optimal performance?

To ensure optimal performance, the depth sounder must be installed on the transom in an area where the water flow is smoothest, with minimal turbulence. It is recommended to position it away from propellers, keels, strakes, and any other sources of disturbance. The transducer must be properly submerged and oriented to ensure clear signal transmission and reception.
