B265LH-12P NavNet TZtouch3 CHIRP

The B265LH-12P is a bronze thru-hull CHIRP transducer for use with NavNet TZtouch3's built-in Fish Finders. 

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 (Compressed High-Intensity Radar Pulse) 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.

The B265LH-12P CHIRPS across the following bandwidths:

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

We know that specific frequencies excel at detecting certain species of fish: Bluefin Tuna—60 kHz, squid—133 kHz, and cod—175 kHz. The B265LH transducer includes all these frequencies plus every other frequency in the high and low bandwidths. This powerhouse delivers excellent resolution, bottom discrimination, and bait and game-fish separation at all depths.

Airmar’s B265LH is packed with a seven-element, low-frequency array that operates between 42 and 65 kHz for excellent deep-water performance. The high-frequency ceramic operates between 130 and 210 kHz with a narrow, 10° to 6°, beam—perfect for picking apart structure and pinpointing tight-holding fish in structure.
