Furuno DST-810MSF Bronze Thru-Hull, Digital Depth, Speed, Temp Sensor, NMEA2000

The Furuno DST-810MSF Bronze Thru-Hull Digital Depth, Speed, and Temperature Sensor with NMEA 2000 connectivity consolidates three critical navigation measurements into a single 51mm hull fitting. This integrated sensor eliminates the need for multiple through-hull penetrations, simplifying installation while reducing the risk of hull integrity compromise—a significant advantage for both new boat construction and retrofit projects where minimizing hull modifications is essential.

The DST-810MSF delivers real-time depth, speed-through-water, and water temperature data via NMEA 2000 protocol, making it compatible with modern marine chartplotters, fish finders, and integrated navigation systems. The sensor features a patented speed-signal-processing algorithm with 5 Hz (5 times per second) paddlewheel sampling, providing responsive speed-through-water readings that track accurately across varying sea states. The bronze thru-hull housing resists corrosion in saltwater environments, while the Airmar B617V transducer design ensures reliable acoustic performance for depth measurements across a wide range of bottom types.

This sensor serves weekend anglers, offshore fishermen, and cruising sailors who depend on accurate water column data for fish location, current assessment, and navigation safety. Weekend anglers benefit from the responsive depth and speed readings during shallow-water exploration, while offshore captains rely on the integrated temperature sensor to identify thermal breaks and productive fishing zones. The NMEA 2000 output integrates seamlessly with existing marine electronics systems, providing a single data source that reduces console clutter and simplifies system troubleshooting at sea.
