Two years ago I had a problem with my 955 that during pool workout it stopped counting pools:
This was apparently solved by a firmware update.
Recently due to a scratch on my 955 glass, I got the 955 replaced in the Garmin shop to a new one.
Few days ago, during my first pool workout with the new watch it happened again.
It counted ok the first 1,100 meters and then stopped the count....
HELP!!
