    Product Description

    DST820 NMEA 2000 Nylon Thru-Hull Smart Multisensor Transducer

    Featuring Airmar’s high-performance Gen2 paddlewheel, the DST820 delivers unmatched speed-through-water accuracy - providing precise start-up data below 0.3 knots, linear accuracy from 0.6 knots, and stable, reliable readings all the way up to 45 knots.

    Whether you’re a day sailor, weekend cruiser, or tactical racer, accurate speed-through-water (STW) data helps you fine-tune sail trim and rig balance for maximum performance. For racers, precise STW readings enable accurate velocity made good (VMG) and target speed calculations on racing instruments, ensuring every tactical decision is data-driven.

    Together, the DST820 and Airmar’s CAST™ app make speed calibration simpler than ever. The free CAST app provides powerful calibration tools—once only available through costly PC-based software—now instantly accessible from your smartphone or tablet. Choose from basic or advanced calibration options to suit your needs.

    Beyond speed, the DST820 measures depth and water temperature, and provides a 5.7 Hz (5× per second) speed output with improved resolution. Its integrated attitude sensor delivers heel and trim data, enabling heel-compensated speed calibration across multiple heel angles and speed ranges—fast, intuitive, and completely independent of onboard instruments.

    With depth tracking from 0.5 m (1.6 ft) to 100 m (328 ft), the DST820 also provides reliable depth data to help ensure you never run aground.

    The DST820 is compatible with Raymarine i50, i60, i70, and Alpha instrument systems, as well as Axiom and Axiom 2 chartplotters. The transducer is fitted with a standard NMEA 2000 DeviceNet Micro-C connector and can readily adapt for SeaTalk NG using adapter cable A06079, sold separately.

    Features:

    • All-in-one depth, speed through water, and water temperature
    • Integrated heel-and-trim (attitude) data
    • High-resolution speed output with improved update rate
    • Simple NMEA 2000 network connectivity
    • Wireless calibration and configuration using the Airmar CAST app
    • PSTI-compliant for cybersecurity
