I have a Garmin swim 2 watch. I am satisfied but I have never seen in the app the data related to heart rates zones.
Instead the heart rate graph has always worked well:
Initially I had set all the user profile information (age, weight, height) and also changed the maximum heart rate setting it to 178 by dedicated menu on the swatch.
In pool activity sessions in the graphs section, time in heart zones the beats per minute of the 5 zones were wrong as always 178-179 for all 5 zones.
I called support. I updated the watch software and updated the app. I also did a reset of the watch and also the value of the maximum heart rate has been reset to 255.
Now the beat values per minute of the 5 zones seem correct and I thought that doing a new session would fix it Instead I see this:
Has anyone solved it? A friend has Swim 2 and it works to him ( android app). Maybe I have to do another reset of the user profile in order to remove all the data: eta, weight, height?
Thank you.
