945 appears to have lost GPS 32 metres into Open Water Swim

Hi guys

Another potential issue here.

I used my 945 for the first time in a lake swim, and after swimming for 1h 7 m and what should have been a 3100 metre swim only recorded as 32 m on the watch.

On checking on Garmin Connect this morning, it only recorded the first 32 metres of the swim and then seems to have lost GPS.

I have recorded stroke rate however through the swim and of course, pressed the lap button on each lap. So the watch was still actively recording the swim, just not the distance.

I am swimming again on Saturday or Sunday, so i will update further if this issue continues.

If it does, I will log it with Garmin.

Regards

James

    So evidence is that it had worked in that time? I don't know what to say about that.

    This was my experience with v2.50: https://connect.garmin.com/modern/activity/4008914634

    I commented a fortnight ago that it was ok I just did not post any pretty pictures. I add pretty pictures and still you aren’t happy. Let’s agree that it’s working now and go with that. I’ll let you know if anything changes as I’m swimming two or three times a week in the sea now.

    The problem is that there's nothing that would explain that it would have been fixed. Not by any release notes / change logs, nor any comment from Garmin saying it fixed.

    I've tested it with v2.50 which gave improvements and it was as bad as it was. So if you are saying it's working now, I would like to hear your speculation what fixed it? And why Garmin hasn't given any comment that it's fixed?

    So I can't just take your word for it. It appears to be working for you, nothing more in my opinion.

    In that case, you'll have to wait until you go back in the open water to satisfy yourself.

    BTW, Garmin often include 'other bug fixes' in their change logs. Personally, I have no interest in how things are fixed, or recorded as being fixed, just that they are.

    Probably, or Garmin announces something, or more people are reporting that they aren't seeing the problems anymore.

    And yes they do, but fixing big issue like this, without acknowledging it, as they have told that it's high priority.. If it's high priority you would probably want to tell that yes, it's finally fixed, not just "other bug fixes".

    Or if it was part of "other" they aren't really trusting that they have fixed it, but then again they could just say "improvements" like they did with v2.50. Only reason if they have done something in the other part that they haven't told is that they don't want to give false hope and aren't really sure they have fixed it.

    For me, as I can't verify it for next six or some months I would like to have the announcement, but in reality it doesn't really matter have they fixed it now or in next few months. If nothing else I can test it when the weather allows.

    I stumbled upon this thread by accident, and I don't have the FR945, so I'm not sure if I will be of any help, but Garmin did acknowledge a fix in a changelog, but not in the main firmware changelog, but in the changelog for the GPS chipset. Please see this thread:

    And that was the version which I used in my swimrun that had big failures. That v2.50 didn't fix it. There has been nothing after that.

    I'm sure will remain unconvinced but here's another swim with the 945 from this morning. The track is a bit too 'wobbly' but that's probably better than filtering out too many points but the distance is close enough. The course is a 2km out and back marked by buoys at 250m intervals. I have an alert every 250m that fired within metres of each buoy.

    and the track from the F6SPro for comparison

    Ok season opened. So with new GPS and firmware it's more like it will lost the start of the swim!?

    BTW. SwimRun auto sports change was crappy, had to disable it during activity as is started to say I'm swimming when I was running and then it was hard to understand the sports change as lap did change it, but there was more lag than one was expecting..

    Also again for some reason the watch did lost HRM-Tri and then I can't download the HR data, and I even tried to do "Resume later", reboot the watch and save it, but then it didn't allow try to download the HR again.. and if you say that you can download the HR later by going to the activity from history.. No you can't with multisport.. 

    I'm not happy. This is more like a running watch, it can handle that, but this seems to be too hard for it. As in one activity I had the following failures:
    - HR
    - GPS tracking the swimming
    - SwimRun auto sports change

    I'm sure philipshambrook will tell me, how this is good and my fault.

    I so hate disappointing people.  Sadly, my swimming is finishing as we head into winter but I have done a reasonable amount since October. I have tried the auto-swimrun setting and found it problematic especially early on. In all but smooth water it lagged in the transition from run to swim and also sometimes changed to run while swimming.After talking with Garmin and trying a few more I gave up and switched to manual. Looks like it’s still not working properly. Also recently found, at least with the F6, the swim track when in swimrun is much coarser than the swim track recorded when in swim.

    But the swims are still being recorded without problems.

    As for issues with the strap? Try a battery change.
