D2 Bravo Titanium

I've had my D2 Titanium 6 months now. I love it! Initially I had some reset issues but those have gone away with software updates. And I close the Garmin Connect App on my iPhone before running to keep it from trying to sync during an activity. I'm not sure if that's needed anymore but "if it works...". I didn't have the D2 Bravo so I can't say anything about comparisons.

I have to admit I use it much more for fitness activities and golf than flying. When I do use it for flying I pretty much keep it on a direct to screen to my home field for fast reference info and CDI. The golf app is great and easy to use.

I haven't quite figured out the altimeter widget and the compass widget seems generally accurate when stationary but I rely more heavily on the GPS track info which is very good when in motion.

Thanks for your reply.
My use will be pretty much like yours. Fitness apps more frequently used and recreational flying. I dont think that the flying features are the reason for buying a watch, investing that money on a tablet or a stratus is way more value. However, the way I look at it, if I am paying 500-600 for a fitness watch from Garmin, might as well pay a little more and buy the aviation features on Bravo (so long as those features dont render the fitness features useless!)

Your feedback is very useful. Good to hear that its a lot more stable now.

My D2 Bravo is generally working fine. Sometimes, I have trouble pulling the nearest airports. Other than that, it is great for what I use (steps, fitness, and rec flying).

Pretty much exactly my thinking! I have a 430W installed in the airplane, and I have been a power ForeFlight Pro user for a long time. I needed a new running and fitness watch and this is a great looking watch IMO, and the golf and flying functions made it a no brainer.

ive had to return 3. thirds a charm. no resets everything works fine. I like you was frustrated with the issues early on. the watch otherwise has been a tank. I use it with the flight stream 510 in my olane and it downloads my flight plans right to it as a back up. as others have said the golf gps is spot on and very easy to read outdoors, keeping score on it is a little problematic at times but not bad. the workout metric couples with the connect app, which i really like work well.
give it another go! or wait until June when they roll out a new one.

D2 Bravo Titanium time is running slow

hello,

I'v got a D2 Bravo Titanium since a few months now and really love it. But has anyone else noticed that time of day is running slow by about 3 seconds per day? I'm dazzled: it's a GPS watch! Should indicate correct time to the millisecond, no?

The D2 Bravo is basically no different than any other computer/device that employs the use of a crystal oscillator in that you can expect it to keep pretty accurate time. I don't recall the level of accuracy but I would expect it to be less than 1 second per day. That said, I also recall that crystal oscillators are calibrated for typical use temperature and that operating in environments outside of this can affect performance. In practical day-to-day user terms, +/- 3 seconds seems pretty good but only Garmin can tell you what level of accuracy to expect. I don't know when my D2 Bravo last retrieved a fix but it was ~5 seconds off.

Your watch configured to automatically set the time? This is done within the "Set Time" menu here: Settings -> System -> Time -> Set Time

Make sure you have that set to "Auto" which means the watch will update the time from any GPS position fix. The D2 Bravo does not constantly receive a GPS fix, which would be required to receive an accurate time. Instead, the time will be adjusted (assuming Set Time is set to Auto) whenever the watch receives a position. So, if you go to an activity which retrieves the current position via a GPS fix, such as the Fly app, you should see the time properly adjusted to match the GPS time. I did this for my D2 Bravo and the time now matches up. I will try to note how much time is gained/lost over the next few days and report back on my watch's accuracy.

Cheers,
Douglas

Hello, thanks, Douglas. Yes I always reset to automatically set the time after I have manually corrected it when it's too far off reality.
So my problem seems to be that I need to increase my "activity" frequency? :-) I calibrate the altimeter regularly using GPS fix, but I'm not 100% sure that it would then adjust the time as well. I will monitor this during a few days and then get a GPS fix while calibrating altitude.
Best regards,

Ha ha, yes -- you need to go flying or exercise more often. Or both!

But in all seriousness, it should be enough to go to one of the activity apps and wait for the GPS status ring around the edge to turn green (which means the "GPS is ready") and the time should be updated. You don't need to actually start the activity.

I don't know about the altitude calibration functionality for sure but I would guess that any GPS fix is enough to correct the tie. As a test I set my watch 4 minutes behind manually and then set the time back to "Auto". I then ran my amazing (*shameless plug*) METAR/TAF widget and selected "Update Position" from the widget's main menu, which I know starts the GPS receiver and waits for a good fix. When the position in the widget was updated I exited back to the watch face and the time was adjusted to the proper time.

Douglas

Indeed that is correct. I verified it just now: my watch was 5 sec behind, I did an altitude calibration and now my watch seems to be 3 sec ahead of what I see on my laptop which is continuously syncing through ntp (and verified on a NIST website). But hey, I'd rather be 3 sec early than 5 sec late! Maybe the watch is so intelligent to add those 3 sec that it will have lost by tomorrow evening haha...

It could be a feature in a future release perhaps: take an automatic gps fix once a day for example?

Thanks!
Roger
