Instinct Solar + HRM Pro = VO2Max and other

HRM Pro does support diverse running dynamics features, but it does not support VO₂max and related features (training effect, lactate threshold, ..). And the HRM Run won't provide any of that - not even the running dynamics features, since it needs a compatible master device for that (unlike HRM Pro, that is a standalone device).

Okay, but so in the case, HRM PRO instead can give you that data as well?

Yes, sorry, I misunderstood :)
Hopefully they will add VO2Max in the next releases.
Otherwise for that I have to use also the old Fenix 3

Interesting, that you for clarifying.  So to make sure I got this right: if you want to record additional running dynamics you need to get HRM Pro, as opposed to one of the cheaper HRMs, as the HRM Pro can record the data on its own memory bank, and then, when you get home, synched directly to your phone, as opposed to using your Instinct (I am assuming the Instinct's small memory is to blame for that).

Yes, that's right

Not only the memory. There may be also marketing reasons, licensing reasons (they use licensed algorithms for that purpose, though they acquired some of the comapnies, in the meantime), and also power consumption reasons. Instinct's main selling point is the battery life, so they removed anything unimportant draining the battery with higher CPU load (VO₂max, Running Dyncamics, Connect IQ, ...)
