Pool Swim - how are you getting on?

I got my watch a few weeks ago and went for a swim. Firmware 3.10.
It was like magic! Each time I finished a length it had counted it and added distance. When I got home I could see stroke, SWOLF and distance.
Really good tracking and motivation.

Updated to 4.2
During the swim the distance looked really high. I then realised that it was adding distance as I watched during a rest. It jumped 210m in one go, then I saw the numbers start to count up like a clock!
When I hit save, the distance dropped dramatically and when I looked on Garmin connect the distance and lengths were close to what I did, with some errors.
This means tracking seems to work OK but in activity, display is out.

I then tested in the living room, doing 'fake' strokes!
15 seconds or so to count a length.
All was OK up to 15 lengths, then it shot up to 31. I hit stop and it reverted to 15 again.

Currently rolled back to 3.1 and the 'fake' activity seems to track OK. Not had a chance to check it in the pool yet.

I have filed a report to the Beta team, but just wondered if anyone else is getting good results? I have seen other reports of oddness with recording and am trying to work out what to do....from install firmware to send the watch back!

I hope it's working for you, but I feel like a guinea pig at the moment - here was me thinking the 5 plus would just enhance the 5 and all bugs were ironed out before launch.

Would love to hear other experiences.

    Breaststroke is not recommended for Open Water Swimming. Since the watch stays under water the device is unable to get a GPS signal. Some 'Best Practices for OWS' can be found in this FAQ link.


    Ok, that confirms that the watch did not produce any usable data when used for Brest stroke swimming.
    It‘s a pitty that the built in acceleration sensor is not used to track swimming at least as good as possible.


  • @Forerunner: When you say track swimming, you mean record distance only, right? Much like using a speed sensor riding in a tunnel.

    Yes, to get as much information as possible from the acceleration/gyro sensor.

    I usually swim 2600 meters freestyle in a 25 meter pool. Typically, my fenix 5+ (and 5x before that) are spot on. With the current beta release the lap graph shows erratic capture and total distance is reproducibly off by one length (25 meters). For me this represents a definite performance deterioration.
  • I roll back to my old Garmin swim because it is unacceptable that interval pace is not displayed until you have finished the interval!
  • Folks, can you advice how to roll back to a previous version of the firmware? I am on 4.2 with problems during pool swim.

    I know pool swim was perfect for me in formware version 3.x so I would like to go back to that one ....

    You need a "system backdate" file. Drop it in the right folder and it rolls back. You loose settings and records.
    It's in the Beta folder, but the latest Beta rolls back to 4.2. Beta 4.61 or before contains 3.1.
    Do you have a copy?

    I've stuck with 3.1 for now - the pool performance is great and everything else I want from the watch is working well.
    I'm going to watch the release threads and give suitable time to stabilise before committing in future.
  • Interval pace and interval swolf data fields are still buggy with 4.65b, you can't see them until you press lap or stop the activity. I have just reported it to beta team for 4.64 beta... no luck...
  • gravity-slave no I do not have a copy of the files for 3.1. Is there a place in the forum where I can find them?
  • You can try here

    If it doesn't work PM me, I can send you the 3.10 file from earlier betas
