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.

Well made but on the small side. I recommend ordering one size bigger than your usual size
Size: Large, Color: Pure Black (Retro Rose)
The fit on this shirt ran slightly smaller for me being a slim fit, so I order the next size up. Getting the next size up gave me a perfect fit. The material is soft and comfortable. I will likely consider similar shirts in the future. I recommend the product.

Very nice shirt -Good Quality
Size: XX-Large, Color: Red (Retro Rose)
My husband is 6'1, weighs 178 pounds and normally wears a medium or large. Just for reference his pant size is a 32-34 depending on the brand. We ordered a large due to the fact the shirt appeared to be fitted more at the waist and from looking at the description I knew it would not have much stretch due to the satin type material. I was right. The large fit perfect and hung well. My husband use to be very large in shoulders and arms, but with age he has lost muscle mass, and recently lost a lot in his belly, so usually mediums fit perfect now. But when he put his large on, a medium would not have fit good to be comfortable & give proper fit in stomach area, so glad we went with the large. The shirt was purchased to go on a Virgin Cruise for Scarlett night, and he plans to wear black pants with it as in the picture the company posted, and this shirt will be perfect for that. It is a nice shirt, good quality, and if someone wanted it for an event/cruise or just for a night to dress up, especially for a Caribbean/Spanish or Latin dance theme, this shirt is a perfect look to me. Buy it, you will not be disappointed. He has not worn it yet, not washed it, but I would not put in it with other colors, may fade a little like reds do, and definitely, only dry on low/delicate. May need a pressing/steaming, but overall, it was not horribly wrinkled when we received it. A toss in the dryer may just do the trick. Was delivered on time as it said it would. Hope this info helps you.
