Given that the marketing program is "More ways to beat yesterday" and the inclusion of things like Stand Up Paddleboard and Stair Stepper, why is something basic like outdoor swimming not included. This is not an advanced sport or fitness activity, in fact it is something most people do, at least sometimes and it's lack of inclusion means that a whole area of activity is not included in your stats. This is also something that Garmin has already figured out and does reasonably well. If they want to be the "fitness smart watch" this needs to be a part of their competitive product. Very disappointed! I would upgrade my less than year old Vivoactive HR, if this were included.
I was wondering the same thing with the Vivoactive HR but came across an answer in the original Vivoactive threads, if you search:
Open Water Swimming with Vivoactive?
There are more details posted there, but it is actually a hardware limitation. The more expensive watches have a different chip that apparently uses more power and does extra calculations for the GPS to compensate for when your arm goes underwater and loses signal.
That being said, it appears that there are people trying workarounds, such as recording another activity type and/or putting the unit in their swim cap to stay above water.
There don't seem to be any good workarounds that I've come across in forums at least, as I think the idea of making an IQ app didn't seem to go through to well. If I am wrong, someone please correct me, as I'd be interested to try if there have been decent apps made.
