Airmar B122 Long Stem Thru-Hull Smart Multisensor - 235 kHz

The B122 has an extra-long housing 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.
