Advanced Medium-Frequency CHIRP Technology for Superior Performance

The Airmar B175C-20-M Thru-Hull Transducer is engineered for serious anglers and marine professionals who demand precision and reliability. Utilizing medium-frequency CHIRP technology, this transducer operates within a range of 85 kHz to 135 kHz, providing exceptional target resolution and enhanced fish detection. With a 20-degree tilted element, it ensures optimal performance for boats with moderate hull deadrise, making it an excellent choice for fiberglass or wooden vessels up to 11 meters (36 feet) in length. The transducer’s ability to cover multiple fishing frequencies, including the popular 88 kHz and 107 kHz, allows users to detect baitfish, game fish, and underwater structures with remarkable clarity.

High-Performance CHIRP Capabilities

Designed for anglers looking to maximize their fishing success, the Airmar B175C-20-M offers 50 kHz of total bandwidth, significantly improving target separation and detail. The CHIRP technology enhances depth detection down to 3,000 meters (10,000 feet), providing a more detailed view of the underwater environment. This high-performance transducer also features a fast-response water temperature sensor, allowing for real-time monitoring of changing conditions.

Durable Construction and Compatibility

Built with a rugged bronze housing, the Airmar B175C-20-M is designed to withstand harsh marine conditions. Its urethane acoustic window ensures durability while maintaining exceptional signal clarity. The transducer is ideal for use on fiberglass or wooden hulls and can be installed on boats with hull deadrise angles up to 28 degrees. This model is equipped with Airmar’s Mix and Match connector, which can be modified to connect with compatible sounders that do not require a dedicated connector.
