The B175M is a bronze, thru-hull CHIRP transducer, ideal for sportfishing and commercial vessels up to 8 m (25 ft) in length. This single-channel transducer offers Medium CHIRP for a balance between the great depth penetration of Low CHIRP, and the superior target resolution of High CHIRP.
- 85-135 kHz Medium CHIRP with 24-16° beam width
- Up to 450 m (1500 ft) range
- 1 internal broadband ceramic
- Thru-hull with bronze housing
- Suitable for fiberglass and wood hulls
- Available in 0°, 12°, or 20° tilted versions
- Ideal for sportfishing and commercial vessels up to 8 m (25 ft) in length
- Recommended for use with the BSM-3 broadband sounder module, SonarHub sounder module & Simrad NSS evo2 multifunction displays
Single Channel CHIRP
Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers target resolution and depth penetration superior to traditional single-frequency sonar. This single channel CHIRP transducer operates anywhere in the 85-135 kHz Medium CHIRP frequency range, with a 24-16° beam width. The B175M provides an operating depth of up to 450 m (1500 ft).
One sensor does it all. Able to measure both depth and temperature in a single package, the B175M simplifies installation and requires just one connection to your echosounder module or multifunction display.
The B175M is also available in 12° and 20° fixed tilt versions to compensate for hull deadrises of 8-15° and 16-24° respectively. With ceramic elements tilted inside the housing to aim the beam straight down without a fairing block, these transducers are able to deliver more accurate depth readings and best cover the area directly beneath your boat.
With bronze housing, the B175M is suitable for thru-hull mounting in fiberglass and wood hulls. Thru-hull mounting places the transducer in the water on the outside of your boat’s hull; a hole must be drilled for installation. This typically offers the best depth measurement and fishfinding performance.
