DST820-PV-N2 PSTI Plastic Thru-Hull with Bluetooth 235kHzThe 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.Beyond speed, the DST820 measures depth and water temperature, and provides a 5.7 Hz (5A- 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 result: industry-leading speed accuracy, wireless calibration convenience, and next-generation security-all in one powerful, compact sensor.Features: The DST820 is fully compliant with UK PSTI security standards, ensuring that the connection between DST820 and a mobile device is secure.; The industry's best speed paddlewheel DST820 features the Gen2 paddlewheel for industry-leading speed performance from 0.3 knots to 45 knots.; Smoother Speed 5.7 Hz speed output (5X per second) for visibly smoother speed-through-water reporting and faster data for better decision making when every second counts.; Integrated Attitude Sensor For heel and trim, and used in advanced speed calibration.; DST820 secure Bluetooth connectivity to Airmar's CAST app provides the ability to:; Calibrate the DST820 in a simple, intuitive way from your mobile device.; Conduct basic and advanced heel-compensated speed calibrations for improved speed-through-water outputs across the speed range.; Advanced speed calibration allows for manual speed entries for multiple heel angles and up to 10 speeds, formerly only possible through expensive PC software.; - cis2:mm5mnJlm -
