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

Looks like the $1500 Marq is affected as well. Check out section 4 below:

Garmin has to react soon! I canceled my order cause of the problems with the 945, there is no hurry for me and my 935.

How do you expect it to work if you are swimming breaststroke? Your hands are under the water whole time? There is no underwater GPS.

Maybe, but here is the exact same course recorded last year with a 935 running 9.2 software https://connect.garmin.com/modern/activity/2749792096/1

And the year before with a 935 running 4.2 sw.

Both tracks look way worse and recorded a longer distance that was about 100 yards more than the actual measured course.

IF you are doing breaststroke it will never, ever work as the watch is under water all the time. GPS only works with front crawl as the arm is out of the water sufficiently long enough to "grab" a GPS reading before it is submerged again.

Swam again last night. Watch set up the same but I switched from Smart to 1 second recording - and it recorded a swim!! Meanwhile, I'd contacted Garmin support on Monday and they finally came back to me last night to tell me that I should return the watch to Wiggle for a replacement.

Well, they already announced (see description of FW 2.5 changes which is pinned in the forum) that they will address this issue with a new firmware (incl.new GPS firmware).

So it could be a "I don't know what's the issue, let the customer replace the watch" answer from support...

Haha - the cynic in me thought that too! Going to wait for a couple of weeks and see what happens - I'm not in a rush..

Yep, 935 has more points on the track. Dunno is the lack of points with 945 some more algorithm trying to get smooth path or just it GPS lock less often when swimming which also makes it smoother.

I’m having the same issue, just reported it to Garmin. Didn’t realise there was a firmware update so doing that now also.
