The Airmar DST810 is a plastic hull-mount multisensor combining depth, speed-through-water, water temperature, and boat attitude data into a single NMEA 2000 transducer. A second-generation paddlewheel delivers 5 Hz speed output for noticeably smoother readings, while the integrated attitude sensor enables heel-compensated speed calibration across multiple heel angles and speed ranges. Built-in Bluetooth Low Energy connects wirelessly to Airmar's free CAST App, letting you perform basic and advanced speed calibrations, configure PGNs, and set output rates independent of any onboard display system. All calibration data and NMEA configurations are stored directly in the DST810 sensor itself.

CAST App Capabilities (iOS & Android via Bluetooth):

• Calibrate speed-through-water independent of onboard instrument brand or model
• Perform basic and advanced heel-compensated speed calibrations across the full speed range
• Enter manual speed values for multiple heel angles and up to 10 speed points — previously required expensive PC-based software
• Enable and disable PGNs; set data offsets and output rates
• All configurations stored in the DST810 sensor, not in the display
