The title says it all. I would like to know if Swim or Swim 2 are the only Garmin watch to measure heart rate under water, while swimming? Does the Fénix 6 have this function ?
If Swim is the only Garmin product line to have this funiction, why is it so? Is this just a way to have you to buy several watches? I bought a Garmin Vivoactive, and my only disappointment was precisely this point, that it cannot measure my heartrate while I'm swimming.
