Furuno CM265LH CHIRP Transducer

Furuno Chirp Transducer CM265LH is a Chirp Transducer from Airmar for use with Furuno's CHIRP >Broadband Fish Finders. The CM265LH features a urethane housing and is designed for tank-mounting applications.

Traditional marine Fish Finders operate at discrete frequencies such as 50 kHz and 200 kHz, use relatively short-duration transmit pulses, and use narrowband Sonar transducers. In contrast, CHIRP uses a precise sweep pattern of many frequencies within a long-duration >Transmit Pulse from a >Broadband Transducer. The equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional marine Fish Finder.

The echo energy returning to the Transducer is likewise superior to that generated by a conventional Transducer. The combination of CHIRP, a >Broadband Transducer, and Furuno’s superior Digital Signal Processing, results in dramatically increased Fish and bottom detection.

CM265LH bandwidths:

• Low-Frequency: 42-65 kHz
• High-Frequency: 130-210 kHz
