Airmar B175M Bronze 20-Degree Thru-Hull CHIRP Transducer, 1 kW, Garmin 8-Pin Connector

B175M Bronze 20 Degree Thru-Hull 1kW for Garmin with 8-Pin Connector

The B175Ms medium frequency delivers the right combination of coverage under the boat, extended depth range, and the ability to produce clean and accurate target and structure returns in mid- to deeper water. Medium frequency also provides excellent shallow-to-mid-depth performance, bottom detail, and fish-target separation. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths of up to 457 m (1500) and gives ultra-clear target resolution.

Airmars Tilted Element transducers have the element fixed at a 20, 12, or 0 angle within the housing. Because the transducer is installed almost flush to the hull, the tilt corrects for the hulls deadrise. It orients the ceramic element horizontally to ensure maximum echo returns to the transducer.

Airmar B175M Bronze 20-Degree Thru-Hull CHIRP Transducer delivers dependable depth and temperature sensing for anglers using compatible Garmin equipment with an 8-pin connector. With 1 kW of power and a medium-frequency range of 85–135 kHz, this tilted-element transducer is designed to provide broad coverage beneath the boat, clear target resolution, fish-target separation, and detailed bottom returns in shallow, medium, and deeper water.

The B175M uses Airmar’s 20-degree tilted-element design to compensate for hull deadrise when installed nearly flush through the hull. This positions the ceramic element horizontally for strong echo returns. Its bronze housing is intended for fiberglass or wood hulls, while the low-profile thru-hull design supports clear display resolution at speed when properly installed. The transducer is recommended for stepped, planing, or displacement hulls with a deadrise of up to 24 degrees.

Built for fishing applications, the Airmar B175M combines depth measurement, fast-response water-temperature sensing, and CHIRP-ready single-band operation in one transducer. The medium-frequency band provides a 16° to 11° beamwidth and a maximum depth capability of 1,500 feet, helping anglers identify fish and structure across a range of water conditions. The included Garmin 8-pin Mix and Match cable supports connection to compatible Garmin CHIRP systems.
