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

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

The DST820 Smart Multisensor is the next evolution of Airmars 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 easieror 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 Airmars 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 45knots.

Whether youre 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 Airmars CAST app make speed calibration simpler than ever. The free CAST app provides powerful calibration toolsonce only available through costly PC-based softwarenow 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 rangesfast, 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 securityall in one powerful, compact sensor.

The Airmar DST820-PV-N2 PSTI Plastic Thru-Hull sensor represents the latest advancement in marine speed and depth measurement technology, combining industry-leading performance with enhanced onboard security. This sensor features a secure QR-code setup for quick and safe wireless connection via Bluetooth, simplifying installation and calibration processes. Connecting your device is as easy as scanning the QR code and entering a one-time security password, ensuring your data remains protected during setup and operation.

Equipped with Airmar's high-performance Gen2 paddlewheel, the DST820 delivers precise speed-through-water readings from as low as 0.3 knots up to 45 knots. The 5.7 Hz speed output provides smoother, more accurate data, which is essential for tactical racing, sail trimming, and navigation. Its linear accuracy starting at 0.6 knots and stable readings up to high speeds make it suitable for a variety of marine activities, from day sailing to competitive racing. Additionally, the integrated attitude sensor offers heel and trim data, allowing for heel-compensated speed calibration across different heel angles and speed ranges, all independently of onboard instruments.

This versatile sensor also measures water temperature and depth, with reliable depth tracking from 1.6 feet to over 328 feet. These features provide critical information to prevent groundings and optimize vessel performance. The DST820’s 5.7 Hz speed output, combined with its wireless calibration capabilities through the Airmar CAST app, streamlines the calibration process. Users can perform basic or advanced heel-compensated calibrations directly from their smartphones or tablets, with the ability to manually input multiple heel angles and speeds for precise tuning. This makes the DST820 ideal for both casual boaters and professional sailors seeking quick, accurate data without expensive PC-based software.
