Hello,
I am considering of buying a HRM-Pro to use it alongside my Fenix 5.
I am wondering if my -4 year old -Fenix 5 will be compatible with all the metrics the band is able to provide (ie: I saw respiration rate is available for Fenix 6 but not for some other devices) or it would be just a waste of money.
Is there some official info where I can check what features are supported by the Fenix 5 watches?
Thanks a lot and happy runs
