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.

The best no sugar natural fiber
Even if you have no problems with your dietary system, fiber is an excellent way to protect your lower GI system. I use the no sugar version as I want the fiber, but I want the extra carbs in the regular version. Regular no sugar is fine, and has no problems with taste. Every so often, I treat myself to this better stevia sweetened version. I don’t take either one 3 times a day, as recommended, but I do take it every morning. If you like the regular sugar free version, give this a try. Since I take it every day, I do like occasionally switching to the better version. Read the labels of your fiber supplement products, if you take them. Very few give you the amount of fiber that this does, and you control exactly how much fiber you want. If you read up on the benefits of adding to your daily fiber intake, you will wonder why you haven’t been adding this to your daily healthy supplements This is a very effective way to protect yourself, and most other products don’t come close!

Great product for bloat and regularity
This works! I try to take a big tablespoon in the morning and if Im feeling bloated maybe one at night. Within a day or two, it helps you get regular! And it makes you go..and not loose, runny stool either. It leaves with that “empty stomach” feeling. I have this set up on auto delivery. Its a bit expensive but like that it has stevia, so am willing to pay the extra. It tastes like OJ but drink it asap or it becomes thick and slime like within a few minutes.

More expensive and not as sweet as regular Metamucil, but no aspartame
I switched to the Stevia variant of Metamucil to cut down my daily intake of aspartame sweetener. The taste definitely isn’t as sweet and invariably some might not like that. I thought the same initially, but after a few dosages of the less-sweet Stevia Meta I’m now use to the taste. For me—less aspartame in my diet is more important than having an overly sweet product. The product functions the same way and is very effective in keeping you regular and the additional fiber in your diet is very important. Try it, but keep in mind it may take some time getting use to the less sweet flavor.

Incredible…
This stuff is incredible. I used to take a psyllium supplement semi regularly but would always stop after a week or so of getting tired of it. This stevia version of Metamucil is better than any fiber I’ve ever taken. Tastes great, dissolves immediately, works incredibly well, and doesn’t get old or repetitive like other versions. Flavorful but not overly sweet. It’s amazing what it does to your poops too. Unbelievable.

Not real sweet, but no sugar
I have been taking Metamucil with real sugar regularly for 20+ years. I became concerned about the amount of sugar I was consuming daily and cannot tolerate aspartame. So, I jumped to buy this when I saw Stevia. I quickly noticed that this version is not sweet. It’s sort of bitter. Also, the texture is different due to not having sugar granules mixed in. It also converts to a gel like texture quicker. I later noticed you use less of this product per serving than the one with sugar (read the label!). I have found the best way to take this is to very quickly (seconds) consume the serving after adding water. Don’t wait too long. I down it like taking a shot out of a shot glass followed quickly by a glass of water. After a while, I got used to the flavor. Overall, I am pleased I am consuming much less sugar and really don’t notice the change anymore.
