Airmar B175 High-Frequency CHIRP Transducer with Mix-N-Match Cable Ends
Model: B175C-20-H-MM
- Combined depth and fast-response water-temperature sensor
- High CHIRP frequency from 150 kHz to 210 kHz
- Suitable for boats 8 m (25’) and above
- 80 kHz total bandwidth from a single transducer
- Covers the popular 200 kHz fishing frequency and more
- Designed for fiberglass or wood hulls
The transducer's ceramic elements are permanently tilted inside the housing to offset the hull deadrise. This makes sure the beam points straight down, maximizing echo returns and removing the need for a fairing.
Flush/tilted transducers fit through a hole in fiberglass, metal, or wooden hulls, with the fitting flush against the hull exterior. Inside, the active elements are tilted to compensate for the hull deadrise, ensuring the sonar beam is vertical.
High frequency means more detail (e.g., 130 - 210 kHz). It's more sensitive to small targets and provides detailed information that shows as sharp, high-resolution images on the echosounder screen. Ideal for shallower water and popular among anglers fishing less than 1500 feet deep.

What's in the Box:
Using this Airmar transducer is straightforward. First, install it through a hole drilled in your boat's hull. Make sure it's a fiberglass, metal, or wooden hull as specified. The fitting should sit flush against the exterior of the hull. When you turn on the device, the permanently tilted active elements will automatically compensate for the hull deadrise, aiming the sonar beam straight down. This gives you the best echo returns.
When using, keep in mind that this transducer is best for boats 8 meters or longer and for fishing in shallower waters, less than 1500 feet deep. Also, it covers a wide frequency range, so you can catch the popular 200 kHz fishing frequency and more.
For maintenance, regularly check the acoustic window made of urethane. Keep it clean to ensure the best performance. Don't expose the transducer to excessive power beyond its 1 kW @ 1% duty cycle rating. This will help keep it working well and extend its lifespan.
