The B122 is a long-stemmed transducer designed for use in thick-hulled, wooden boats or vessels with a steep deadrise. The included high-performance fairing vertically orients the beam for strong return echoes, resulting in optimal performance even at higher speeds. And being a retractable design, the insert can be removed for servicing or storage. All that is needed to receive depth and temperature data is a single cable run to a compatible instrument or display.
