This was also an issue with a 530 and I was hoping there would be an updated altimeter in the 540. That said, I'm not sure which one is more accurate. Both are on 'auto calibrate'.
acousticbiker Yes, both activities will be available as long as you save both and then sync each device. Your training status information will not be duplicated and will be used from your primary device. You can delete the duplicate later after we have had a chance to look over them, but we will need both to compare of course.
Different devices will have their own hardware internally, as well as overall designs so there can be discrepancies, but we can look into this once you have some uploaded.
Garmin-Blake I finally got back out and saved a ride today from both epix and 540 solar showing 1779 ft climbed on former and 1572 ft on latter.
In addition, during one ClimbPro segment, the right data field under the elevation profile showed ‘nan’ at the beginning and end of the climb while showing a fixed amount of ft remaining throughout (and no elevation profile) even while distance remaining was decreasing appropriately.
