Comparing Chirp to Traditional Transducers 

Mike Smedley shows the difference in quality of return between his TM150 Chirp transducer and a traditional p66 transducer. Watch the Video Now

Traditional marine fishfinders operate at discrete frequencies such as 50 kHz and 200 kHz, use relatively short-duration transmit pulses, and use narrow band sonar transducers. In contrast, Chirp (compressed high-intensity radar pulse) uses a precise sweep pattern of many frequencies within a long-duration transmit pulse from a broadband transducer, so the equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional marine fishfinder. The echo energy returning to the transducer, superior to that generated by a conventional transducer, is then processed by the fishfinder’s DSP (digital signal processing) computer and displayed in ultra-sharp detail on the display. The combination of Chirp, a broadband transducer, and the fish finder’s DSP, results in dramatically better fish and bottom detection, superior depth capability, and significantly better performance at speed.

 


When Your Living Depends on Finding Fish...

Rely on Airmar’s new Chirp ready transducers for the ultimate fishing mission. Whether you’re a commercial fisherman, charter captain, or tournament angler, there’s a new game in town! Chirp transducers enable bottom detection down to 3,000 m (10,000’) with 5 to 10 times greater detail and resolution so precise it’s possible to distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to 117 kHz of total bandwidth in just one installation, saving customers time and money.
