Airmar B75H CHIRP Transducer, Garmin 8 Pin

More Views

The B75 comes in 3 frequency bands, Low, Medium and High. The high frequency band is designed to have excellent target resolution while the fact it is CHIRP means it will still have good depth penetration.

This transducer is available with 0 degree tilt (straight down), 12 degree tilt for hulls with 6-15 degree deadrise and 20 degree tilt for deadrise of 15-25 degrees. If you would like a tilted model, please make a note when purchasing.

This is one of the through hull transducers for the GPSMAP557xs and GPSMAP751xs. 

High Chirp - from 130 kHz to 210 kHz, 15° to 9° beamwidth
• Available in 0°,12° or 20 tilted versions
• 80 kHz of total bandwidth from one transducer
• Covers popular fishing frequency of 200 kHz plus everything else in the bandwidth


When Your Living Depends on Finding Fish...


Rely on Airmar’s new broadband 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 greater detail and resolution so precise it’s possible to distinguish between individual baitfish, game fish, and underwater structures. 


The CHIRP Difference


Traditional marine fishfinders 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, 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 fishfinder’s DSP, results in dramatically better fish and bottom detection, superior depth capability, and significantly better performance at speed.


Does YOUR Fishfinder CHIRP?


Only CHIRP/Spread Spectrum sounders using Airmar broadband transducers can operate as a CHIRP fishfinder system. When Airmar’s new transducer is paired with a broadband fishfinder, the result is 5 to 10 times greater sensitivity and performance than current fishfinder technology. Packed with exclusive technology like
Transducer ID® and newly engineered piezoceramic elements.  As a result, all targets detected in the entire bandwidth will be seen on the display rather than only what is identified in traditional frequencies at 50 kHz and 200 kHz.
