Airmar Med CHIRP B175M Thru Hull

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.

Key Features

• 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).

Depth/Temperature

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.

Deadrise Compensation

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.

Mounting

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.
