Airmar DST820-PV-N2 PSTI Plastic Thru-Hull with Bluetooth 235kHz

Overview

DST820-PV-N2 PSTI Plastic Thru-Hull with Bluetooth 235kHz

The DST820 Smart Multisensor is the next evolution of Airmar’s industry-leading technology, replacing the DST810 and introducing PSTI compliance for enhanced onboard network security.

With its secure QR-code setup, connecting your DST820 has never been easier—or safer. Simply scan the QR code and enter a one-time security password on your mobile device to protect your sensor on the network.

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, 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.
