    Way to go Airmar, great feature set! Kees, sounds like we can get leeway on a smartphone using Bluetooth while the sensor is connected to our boats sans leeway reporting capable MFDs?
    Is leeway and or the full nmea2000 sentences of the high end sensor included in Signal K 1.0? Please see my questions for you in last Panbo entry.
    Thanks Kees!

    I have to write again, I am a big fan of measuring leeway, but I am also just blown away that a thru hull sensor gets bluetooth connectivity to smartphones.
    All marine electronics vendors should evaluate follow Airmar’s leadership here. The ability to configure, calibrate, and update sensor software over bluetooth from a smartphone is ground breaking in marine electronic sensors, and almost(?) ground breaking in marine electronics as a whole.
    Take the very latest Triton and the IS42 in this entry for example, Airmar leaves them in the dust when it comes to software updates. How much trouble would be saved by boat installers and boat owners in the future if updates were bluetooth instead of a USB port behind the instrument. (idea: maybe a future USB bluetooth dongle can plug into the Triton ?)
    Then what about new features, when the MFD and instrument display manufacturers don’t keep up with sensor provides like Airmar and Maretron the boat owner is deprived of innovative features? Five years ago I installed Maretron fuel and battery monitors, and could not get the full feature set on my instrument displays years later, and maybe not even today? (For example displays show Voltage, but not remaining battery capacity in percent or minutes of time remaining)
    Right off the bat, users of the new Airmar DX900+ will be able to get leeway (via bluetooth) without waiting for their boat electronics to catch up. Day 1. Yes, we would like to see it on our instrument displays and part of navigation math, but it’s quiet possible that capability won’t show up in all the major MFD brands until well after 2017. But it will be on my smartphone Day 1.
    Way to go Airmar!

    Kees, what should MFD and PC based vendors keep in mind when they choose to incorporate leeway into their calculation of truth about the environment around out boats? For the first time they will know if our sails are up or down, our boats are in reverse, perhaps have new information to calculate set/drift, true wind, ground wind, and I suppose some racing boats will have two of these, and there are implications for motor boats as well (better display of the cross currents in a harbor), and for those MFDs that predict set/drift will they show the variance?

  4. Robert Dyas says:

    Ben, was there any info from B&G as to if the Zeus3 will support ActiveCaptain with CMap charts (or maybe even any chart)? If so, how do updates work? Very curious on this as I find it highly useful in the Bahamas (broken off markers) and ICW (shoaling reports). I find the Garmin iPad app great for this, but would really like it on the waterproof display in the cockpit.

  5. Kees says:

    Hi Dan,
    Sorry I missed your questions — I only get emails regarding comments once I write a comment on an issue myself.
    There is a “Set & Drift, Rapid Update” PGN 129291 in NMEA2000, and is in Signal K 1.0 as well.
    I predict my current Tritons and MFD can display this just fine.
    The Racegeek guys were present at the Signal K meetup, and showed off their coming display which looks really slick. I can’t really comment on their schedule though.
    I haven’t heard anything about ActiveCaptain from Navico, but that doesn’t say much as I haven’t asked.

  6. Dan Corcoran (b393capt) says:

    Kees, I am confused. Leeway isn’t set & drift. Does Airmar populate PGN 129291? Do they populate it as leeway or do they calculate drift and stick it in 129291?
    Leeway has been so incalculable that I didn’t even include it in my earlier Panbo post.

  7. Kees says:

    Dan, you’re right. I shouldn’t answer in the middle of the night.
    With the DX900+ the measured boat speed relative to the water becomes a vector in a plane with the leeway defined as the orthogonal vector to fore/aft speed, and the fore/aft vector identical to what is traditionally called boat speed.
    Set+Drift is the difference between that vector and the GPS SOG+COG vector. SOG+COG and Set+Drift are both expressed as the length of the vector and a direction (in N2K.) You could argue that we should now express boat speed as a single vector length and direction as well.
    I don’t have any information yet on how this is transmitted over NMEA 0183 and 2000, but will try to find out.

  8. Kees says:

    Just heard back, if you have a CMAP card with ActiveCaptain data the Navico plotters will display it just fine. Updates to the data come with the chart updates.

  9. Ben Ellison Ben Ellison says:

    Robert, C-Map Max-N+ chart cards for Zeus2, NSS evo2, etc. have had ActiveCaptain data since last spring. I’ve seen it looking pretty good on a NSS7, but as Kees notes it is a static copy of the AC database so you won’t see new AC data until you get an updated card. More info here:
    But if you can wait, C-Map (which is now a sister company to Navico) just announced a new format called C-Map Insight Pro which sounds very interesting:
    The press release doesn’t mention availability for the Bahamas but that may be included, or added separately. ActiveCaptain is definitely included, probably in a more easily updated way, and Insight Pro will also include the detailed soundings data that some Navico users like me have been collecting for years. That means serious competition for Navionics SonarCharts.
    Meanwhile an interesting aspect of the new evo3 and Zeus3 displays is that they will support Navionics auto-routing and crowd-sourcing as well as C-Map’s, and apparently the new C-Map Insight format is going to available on Raymarine and Furuno displays. Behind all the intense competition there’s some cooperation going on, which sounds good for us ๐Ÿ˜‰

    Does Airmar have an ultrasonic speedo w/ or w/o depth and temp which fits into their DST800 thru hull, The price of the reviewed item is too spendy. I am looking for a non moving part (subject to marine fouling) speedo that I can fit in the existing thru hull hole… which will work with my present instruments… which I will be upgrading at some time in the future… The Airmar DST800 works so that is the standard for me. Any ideas?

    The IS42 and AP44 USB update option is an additional update path intended for customers not having a recent Simrad, Lowrance or B&G MFD. In a Navico system all updates, including NMEA 2000 devices, are intended to be done over Internet. I can’t see any advantage of a Bluetooth option for the update for customers with a Simrad system. The situation is of course completely different for companies like Airmar and Maretron which don’t sell complete systems.

  13. Kees says:

    Jeffrey, the ST900/950 may be what you’re after. I have no price information on that yet, maybe it is cheaper than the DX900+. It is speed (S) and temperature (T) only.

  14. Kees says:

    Hi Abbor, the IS42/AP44/Triton2 is running the same (Linux) OS as the MFD, the download is probably 50+ MByte instead of <1 MByte for the earlier IS40/IS20 devices. Like MFDs the IS42/AP44/Triton2 series cannot be updated remotely. Unlike MFDs the IS42 don’t have an ethernet connection so they cannot update themselves over the internet.
    From the manual page 65:
    The IS42 includes a USB port of the back of the units. You use this port for software updates. You can update the software for the IS42 unit itself and for NMEA 2000 sensors connected to the network from the IS42.

  15. abbor says:

    Kees, I’ve been looking into this and you are right. By looking at version and platform numbers in the manual I can see the new displays are running Linux and NOS. Then WiFi, not Bluetooth would be the solution for wireless updates. I did not imagine they were using Linux for such a simple device, the advantage is of course software reuse. I Think I will stay with IS40, AP24 and AC12 which reboots in a few seconds instead of upgrading and have to wait a close to a minute when I have to power cycle NMEA 2000 to get contact with my Suzuki motor interface again.

  16. Hendrik says:

    Quit happy with AP44, IS42 and NAC2.
    Yes it takes some time to start, but I don’t feel it as disturbance.
    I powercycle N2K quite a lot a the moment ๐Ÿ™‚

  17. Jorgen C says:

    Does anybody know if the new Airmar 900-sonar series tolerate being covered by antifouling (year after year)? Or perhaps it can shoot right through 2 inches of barnacles?
    Regarding the concern over how to update the new Navico instruments over USB without having to rip out the instrument from it’s delicate 6 mm fitting, I think the best way to go would be to leave an USB cable attached to the instrument when installing and let the other end of the cable exit the instrument housing at some discrete location.

  18. Ben Ellison Ben Ellison says:

    They’re obviously about to be discontinued, but Defender has very attractive deals on remanufactured Zeus2 displays:

  19. Sea Logic says:

    THEY ARE STILL NOT SHIPPING as 3/21/2017 Not sure were this info came from but it is wrong. This has been in the making for years. Same answer.

  20. Scott says:

    With you Dave. Been waiting too long for the Dx900. Would love to give my money to someone so that I don’t have to pull the transducer out and clean the paddle wheel every time I go out. Are there any other options for getting water speed on N2K without a paddle wheel?

  21. Kees says:

    A short update on the DX900+, I’ve been testing one and off. At the moment I’m waiting for Airmar to ship me a new one. Whilst not ready yet (some real-life snags were hit) it is definitely coming. I guess we have to be patient. And boy is having leeway displayed directly interesting!
    You can paint the plastic bits on the DX900+ but the stainless steel pins need to remain uncovered. You can paint the entire thing and then scrape the paint off the pins, with something non-metallic (wood or plastic f.i.) but after that you may need to re-calibrate.

  22. Dan Corcoran (b393capt) says:

    Thanks for any news you can share Kees!

  23. Anonymous says:

    Hi Kees,
    Any updates on your testing of the DX900+? Please share what you’ve learned so far. Thanks.

  24. Bill Coleman says:

    After about 3 years of the DX900+, I can say I wish I had just gotten the ultrasonic. The temperature has been crazy over this period, but lately has settled down, and seems correct. The Depth is the star, I can say I believe it is better than any other technology I have used. Where is shines, is in weeds, muck, or other uncertain bottoms, as it seems to shoot right through all that and give accurate readings. Best of all, it is on all the time. Which leads me to the speed. It will only report for a couple hours, sometimes the whole day, but never to the time I turn it on next. Temp and Depth are always there. What works best is if I unscrew the the Nk2 connection, then reconnect, it pops back up. But it will never follow through from one power cycle to the next. Which means I need a new transducer. Not happy with this one.
