A discouraging thing I just noticed, I used the top menu to go to the Beta Program. There are change logs for each of the Beta candidates more recent than the current "Live" version. There was much of nothing mentioned in the Beta Change Logs for addressing the bad HR data.
Garmin-Sierra Where is Garmin at in coming up with a solution to make the HR data to be at least as reliable as it was back in the FR245 days? Had I known I was buying a crusade rather than (what I thought was a desirable upgrade to my FR245), I wouldn't have. If there isn't some reasonable fix to the HR problems, or if Garmin ushers in a new HR sensor that is at least as reliable as the FR245's version and doesn't offer us poor saps that invested in the FR265 / (FR255) " a really serious discount to get something that actually works, taking another chance on a Garmin product without assurances that the HR has been fixed is not a mistake I will repeat.
I'm not talking medical grade data, or absolute max peak instantaneous values, just respectable reasonable data that doesn't suddenly jump for no reason 10 minutes into an exercise, well no reason other than it was reading wrong for the 1st 10 minutes.
So point blank Garmin-Sierra is Garmin making a serious effort to address the HR data problem?
Did a 4km walk, most time with garbage readings.
