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.

Why the revisionism?
Format: Paperback
I kinda want to give this a try but I dislike that the artist chose to change Robin's costume. What is this? Dick Grayson Robin always wore the same costume, so why is a "throwback" story using new uniforms? (Batman's is also not quite the original.) I guess modern readers just think the classic togs are "silly," but that's on them. Respect the material, comics creators! Or leave it alone.

Simply magnificent
Format: Kindle
A new perspective on an old and familiar story. The art is outstanding. The story is compelling. It needs to be a regular ongoing series. DC...please handle this. Thanks.

Probably the best thing to come out of the "New 52" reboot
Format: Paperback
In general, I'm not a big fan of the new 52 reboot of the DC universe. On the other hand, it produced this really interesting investigation of the iffy morality and general maladjustment and emotional fallout caused by the "child soldier" issue of the multiple underage vigilantes in the Batman family of comic books. The scripting for this story is excellent, in that it makes clear the broad range of personalities represented by the 4 Robins, Bluebird, Spoiler, and Black Bat (who isn't named as such in this particular story for some reason), and aside from that the art is really gorgeous. I think this may very well be the best thing to come out of the new 52 reboot.

Don't listen to the negative reviews. There is so much to love in this story.
Format: Paperback
First off, I would like to say that this is mostly for people who either A) bought vol1 and want to finish the story, and B) fans of not only Batman, but also the "legacy" that he has left behind him. More on that later. This is the second half of the weekly 26 week story revolving around The former robins, and deals heavily around The Spoiler, Cassandra Cain (batgirl) and Harper Row (bluebird) the main thing I have to say about this story is that it more effectively does what "batman eternal" and "Robin war" we're trying to accomplish. In batman eternal, the story was over 50 issues long, and there were so many times where the story was abysmal because of filler and boring events that made it feel like such a cash grab, and with Robin war, by the end of that story there is almost nothing important that happens, leaving you to feel like you could have went without reading it. Batman and robin eternal not only tells a captivating story, but with important enough events that justify your time and money put into this story. I can whole heartedly recommend this to ANY fan of not only Azrael (very important character in the 90s when knight fall was going on) but also Cassandra Cain (new batgirl up until 2011) and they in my opinion are the highlights of this story because of the justice they are given as comic book characters. We haven't seen them since in the new earth, so it's nice that they got some recognition before rebirth. Hopefully we see them more, but this is also a solid story for the robins as well, each of Batmans pupils gets justice at some point in the story, so I can say a fan of any of them will be pleased. I can say this especially as a Red Hood fan who longs for the day that Jason Tood will finally get a good/solo ongoing series. Now with that said, the art can be inconsistent seeing as how there are more than one of them, and the "big plot twist" shown in this second half can be pretty obvious that "there's more than meets the eye" with the situation, but I rather not give spoilers. Again This book is MORE THAN WORTH YOUR TIME AND MONEY if you Like ANY robin Like Scott Snyders "bluebird" Like the old ninja looking batgirl Like Azrael Like batman stories that don't have batman as the main focus
