When paired with either the CP100 network sonar module or any DownVision capable Raymarine display, the CPT120 brings CHIRP DownVision to life. Unlike conventional transducers that transmit a single frequency with each pulse, the CPT120 is a CHIRP DownVision transducer that transmits across a wide spectrum of sonar frequencies with each pulse - the result is much higher resolution, photo-like sonar images. Compatible with Raymarine CP100, a68, and a78 models.
