High-Performance Wide-Beam Chirp Transducer for Superior Marine Coverage

The Airmar B175C-20-HW transducer is designed for anglers and marine professionals seeking unparalleled bottom coverage and precise fish detection. With its wide-beam CHIRP technology, this transducer operates within a high-frequency range of 150-250 kHz, ensuring clear and detailed sonar imaging. Whether installed on fiberglass or wooden hulls, the B175C-20-HW delivers optimal performance for boats measuring 8 meters (25 feet) and above.

Unlike traditional narrow-beam transducers, this model offers a consistent 25° beam width across the entire frequency band. This ensures broader underwater coverage, making it easier to detect fish throughout the water column. The B175C-20-HW also enhances echosounder performance, producing larger and crisper return images on display screens for improved target identification.

Equipped with a powerful 1 kW rating and a fast-response water-temperature sensor, this transducer is a reliable choice for serious marine applications. Whether navigating coastal waters or deep-sea fishing, the Airmar B175C-20-HW provides unmatched clarity and accuracy beneath the surface.
