B122 DT Long Stem Bronze

The B122 is a long-stem, through-hull transducer specifically engineered for thick-hulled wooden boats or vessels with steep deadrise angles. Its extended housing ensures proper installation in challenging hull structures, while the included high-performance fairing aligns the transducer beam vertically for strong echo returns and accurate readings, even at higher speeds. The retractable design allows the insert to be easily removed for maintenance or storage without compromising hull integrity. With built-in temperature sensing and a straightforward single-cable connection, the B122 delivers reliable depth and temperature data to any compatible instrument or display.
