Forerunner 935 vs 945 - Open Water Swim (GPS Accuracy)

Hi All - Two of us open water swam Thursday with a 935 and 945. I have the 935 and it had me swimming 3:13/100yd! I’m usually 1:45/100yd.

My 935 has the latest updates. Is there something wrong with my watch? It’s a few weeks old.

See our swims below.

The track suggests there might be something wrong with your 935. Have you looked for posts about OWS in the 935 forums? Perhaps have a look there and follow any advice. If nothing makes any difference contact the place where you bought the watch or Garmin Support.
