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.

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.

Good, but size up!
Color: Black, Size: 30W x 29L
These are exactly what I wanted, but as many have stated, you need to size up. I found that going up two sizes (from my usual 28 to a 30) made for a great fit. I love that they come in a 29 length. One anything point is they came with creases in them from being folded in the package for a length of time. I had to steam and press them before wearing. I’ll likely buy them in other colors.

Great pants but buy one size up in the waist. They are well made, comfortable, and good looking. They are Dickies brand what more needs to be said.

order 3 or 4 inches up than your usual waist, run very small in waist
Color: Charcoal, Size: 33W x 30L
arrived with dirt on the bottom legs but amazon helped with that. anyway I weigh 115 lbs and am 5'8 and I am a woman. I know that Dickies these days run super small for their size, so it sounds insane but order up 4 inches than your normal waist size, then run small in the waist and they will shrink a size with a few washings. I ordered a 33 waist and they did shrink probably a size in one wash lol! they are still a bit loose in the waist but not big and I know with a couple more washings they will be just right. I do not like anything skinny fit or with no give. but yah, I love the charcoal gray color, one of my favorite colors, much cooler than plain black. I normally enjoy the Dickies shorts but with these forty something degree afternoons these are my new go tos. I am not a jeans person and I sure as hell with not be wearing pajama pants out in public like these dang younger adults lately.

Perfect fit every time
Color: Silver, Size: 30W x 30L
These original 874’s are the real deal. Stocked up during the sale and got them for my husband. He loves all the colors and the durability of these pants is incredible. He still has some from 14 years ago! But he wanted a few new ones- and they had more colors so I stocked up and surprised him when I told him how much they cost during the sale. These pants never wrinkle. I wash them hot and air dry- no wrinkling or shrinking. They look great. They’re sewn to perfection. The quality is there and has been for years, a reason my husband only wears these. Quality, value, durability, style, fit. Great for all seasons, they’re not too heavy or too light. Great functionality- pockets for everything . Great even in summer - they are very breathable. Perfect fit every time. Great for heavy road construction or just going for a hike. Highly recommend!
