Airmar Low CHIRP B175L Thru Hull

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 40-60 kHz Low CHIRP frequency range, with a 32-21° beam width. The B175L provides an operating depth of up to 1200 m (4000 ft).

Depth/Temperature

One sensor does it all. Able to measure both depth and temperature in a single package, the B175L simplifies installation and requires just one connection to your echosounder module or multifunction display.

Deadrise Compensation

The B175L 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 B175L 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.
