When I look at tracklog elevation data what am I seeing, GPS elevation or Altimeter elevation?
It depends on the Barometer Mode setting (Main Menu>Setup>Altimeter>Barometer Mode). If you have this set to “Variable Elevation” then the tracklog contains Altimeter elevation. If you have this set to “Fixed Elevation” then the tracklog contains GPS elevation. This is the same as on the 60csx and Colorado.
