Airmar B175HW Bronze 20-Degree CHIRP Thru-Hull Transducer, 1 kW, Garmin 8-Pin

B175HW Bronze 20 Degree Thru-Hull 1kW for Garmin with 8-Pin Connector

Get more coverage under your boat with Airmars unique wide-beam, high-frequency, Chirp-ready B175HW. The high band operates across a frequency range of 150 to 250kHz and has a fixed 25 beam for all frequencies. The high-frequency band delivers superior shallow-water performance, bottom detail, and fish-target separation. The constantly wide beam provides twice the coverage for detecting fish in the upper-water column and clear fish arches on the display compared to most high-frequency, narrow-beam transducers. The high wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage under the boat are essential down to 152m (500).

Tilted Element transducers have the element fixed at either 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 B175HW Bronze 20-Degree CHIRP Thru-Hull Transducer delivers broad, high-frequency coverage for anglers who need detailed bottom information and reliable fish-target separation beneath the boat. Designed for Garmin systems with an 8-pin connector, this 1 kW transducer combines depth and fast-response water-temperature sensing in a low-profile thru-hull housing.

The B175HW operates across a wide 150–250 kHz frequency range with a constant 25-degree beamwidth. This high-wide beam provides increased coverage in the upper water column compared with typical high-frequency narrow-beam transducers, helping anglers identify fish arches and observe bottom detail in shallow water. Its 100 kHz total bandwidth includes the popular 200 kHz fishing frequency and is CHIRP-ready for inshore and pelagic fishing applications to depths of up to 500 feet.

The tilted-element design positions the ceramic element at a fixed 20-degree angle inside the bronze housing. This helps compensate for hull deadrise when the transducer is installed nearly flush, orienting the element for effective echo returns. The B175HW is recommended for stepped, planing, or displacement hulls made from fiberglass or wood and supports vessels up to 36 feet in length. Airmar Xducer ID technology helps provide transducer identification for compatible systems.
