DST800L B122 Long Stem Triducer
The DST800L is a Smart™ Triducer® Multisensor that delivers depth, speed, and temperature data through a single thru-hull fitting. Featuring a long-stemmed design, it’s ideal for thick-hulled wooden boats or vessels with steep deadrise angles. For enhanced performance, an optional high-performance fairing vertically aligns the transducer beam, ensuring strong echo returns even at higher speeds. Built on Airmar’s proven Smart Sensor platform, the DST800L integrates microelectronics directly within the housing, processing data right at the source. Depth, speed, and temperature information is transmitted via a single cable to any NMEA 2000® network or compatible display for real-time monitoring and control. The sensor’s wide, fan-shaped beam is capable of accurately detecting the bottom, even when installed on a high-deadrise hull or a heeling sailboat.
Note: The DST800L is the long-stem version of the DST800, housed in a B122 body.
