DST820 Bronze Thru Hull - NMEA 2000 - 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.

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 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.

Great, necessary read
Format: Hardcover
One of the greatest forgotten stories of the civil rights struggle in America. Major influence on the Black Panther Party, was a required read for initiation when it started.

I love this book
Format: Paperback
I love this book. It actually explains in details what concentratio (Dharana), meditation (Dhayana), and contemplation (Samadhi). It is very interesting to know that if we can concentrate 12 seconds on external or internal object, then we have successful concentration, 12 of these (12x12) is Dhyana and twelve of these (12x12x12) is Samadhi. I tried it and got Samadhi after half an hour, of course it needs few month of daily practicing. The book also speaks about attaining magic powers after long time of practicing, but of course we need Yogi master to achieve that. Raja Yoga is the origin of the Sufi systems that originated after Muslims lived in India.

Phenomenal
Format: Paperback
This is one of few books that actually describe, in an accessible manner, how to control the mind during meditation. Particularly the last two chapters of Raja Yoga (the second part of the book is Patanjali) are some of the most valuable pages on meditation I have come across (easily 20+ books). Highly recommend for the practitioner.
