I have started swimming weeks ago and thanks to you guys I have discovered drills. Would be a good addition as my Trainer counted 2 laps instead of 1, three times while I was doing drills. So 60 meters over the true distance.
Hope this will come in a next watch/app update.
To finish on a positive note I am very happy with my Trainer as the owhr works surprisingly well while swimming and when swimming laps, no drills, it counts well the laps.
