For some reason I always thought that the MARQ aviator (and D2 DeltaX) would automatically take PulesOX readings during a fly activity (and I think I remember an activity that showed records without having turned on all-day measure), but looking through my records that might not be the case...
Do you have to turn on the all-day SpO2 measuring prior to flying, or does it do it automatically (it might fail due to excessive vibrations or movement etc which could explain why I didn't see any records)?
Does anybody know? Garmin-Heath?
