Breaking Down the Features of Raymarine MFD Sonar Accessories And Transducers CPT-100DVS Transom Mount Transducer

Specifications

This Raymarine unit is characterized by its specific technical attributes designed for optimal sonar performance. The CPT-100DVS Transducer operates using two distinct frequency bands: 350KHz for CHIRP DownVision and 200KHz for standard CHIRP sonar. These frequencies are critical; the higher 350KHz band is responsible for the high-resolution, near-photographic images of DownVision, while the 200KHz band provides deeper penetration and broader target detection typical of traditional sonar. The transducer itself is housed in a durable, black casing, built to withstand the marine environment.

As a transom mount unit, its physical design is optimized for external hull placement. The MFG# A80351 designation identifies it specifically within Raymarine’s product line.
