Meet the Garmin DST810 Smart Transducer (Model: 010-11051-20), a breakthrough Airmar through-hull sensor designed to elevate speed, attitude, and hull data for both sailing and powerboats. Encased in a robust plastic hull, this sensor delivers 5 Hz speed-through-water data (five readings per second) for visibly smoother readings and faster, smarter decisions on the water. The integrated attitude sensor captures heel and trim, providing context that helps you optimize performance and efficiency.
Connectivity and calibration are redefining how you tune your rig. The DST810 connects wirelessly to Airmar’s CAST App, delivering a simple, brand-agnostic calibration experience no matter what display or instrument brand is on board. Calibrate quickly with basic heel-compensated speed calibrations or dive into advanced options for precision across multiple heel angles and speed ranges. The result is accurate speed-through-water outputs across the entire speed range, without the need for expensive PC software.
The DST810 stores all speed calibrations and NMEA configurations in the sensor itself, independent of your onboard displays. This means consistent performance across systems and easier upgrades or changes to helm instrumentation. With the CAST App, you can:
-
Enable or disable PGN’s and set offsets and output rates
-
Perform heel-compensated speed calibrations across multiple heel angles and speeds
-
Calibrate across up to 10 speeds with manual entries for precise tuning
-
Calibrate regardless of instrument brand or model on the vessel
Why the DST810 changes everything
This Smart Multisensor – paired with the CAST App – converges advanced hull data with a simple, reliable calibration workflow. It delivers capabilities that previously required expensive PC-based software, but now fits in the palm of your hand. In addition to speed-through-water, you’ll benefit from reliable water temperature and depth data, plus an accurate attitude reading that enhances data interpretation and decision-making on every voyage.
