SUBJ.: Forerunner 310XT - Elevation fluctuation
I used my Forerunner 310XT for about 3 years (both cycling and running).
During the last year I'm continuously experiencing false elevation fluctuation.
For instance, riding on a continuous rise, sometimes you can see the elevation decreasing.
Consequently, the total ascent value at the and of the track is higher than the the right and the instantaneous percent slope is fluctuating too.
This happening seems not directly correlated with lack or weakness of GPS signal...
Have anyone suffered something similar and is there a key for this?
Thanks in advance to everybody!
