Galaxy watch 5 pro not tracking swimming accurately

[Rijedo]

My swimming app in Samsung Health consistently gives incorrect lap counts and distance while swimming front crawl and breaststroke, nearly 25% more lengths than I've actually swam. I've cleaned, the sensor, reset the watch and have tried GPS on and off. Nothing seems to be working. Any help would be appreciated, thank you.

Have you set the proper length of your pool? On the watch's exercise tile or in the watch's health app, rotate to the pool swim and scroll up til you get to the settings. Scroll til you get to the pool length setting snd change the length. The lowest you can go is 25 meters, so if your pool is less than that, that's what your laps/distance will be based on. It does not use GPS to measure distance.

Hi thanks for the quick reply, I'd already set the length to 25m and it doesn't seem to make any difference. It still measures way above what I'm actually doing. If it was one or two lengths out I wouldn't be bothered but it's so high it has become useless as a metric

Many people have made a feature request to be able to use a shorter length. But then you would also have to know the length. I would like for them to use GPS to make the length determination. The only metric I take seriously is time. I don't even trust the heart rate, since it's all over the place and I swim at a steady pace.

Thanks for the input, I agree with you about the heart rate measure! Previously I had swam without giving consideration to how many lengths I actually did but my friend has encouraged me to do less lengths and have better focus on technique and this is what has alerted me to the discrepancy. I'll just have to count which is frustrating, maybe there will be an update or someone else may have a fix.

Just had another play around with the settings in the pool tile and there is a "custom" setting for pool length which goes all the way down to 10m. I may try playing around with it at the pool later this week. there is also a "target" setting that can be set to either lengths or duration which I'll have a look at.

Oh, they must have just added the 10m, I haven't looked in a while. Yeah, i set my target by time and split guide every 10 minutes.
