So this morning I travelled a very well know route that has been recorded with both my Garmin 235 and my iPhone 6. Both of these devices measured very close to the same distance, within 10-15 steps variance between the two over the course of a mile. Today I took the new AW 2 with me and turned off bluetooth on the phone so the watch was forced to use its GPS. At the normal one mile marker the watch was reading .96 miles. At the conclusion of the route when the distance is normally 1.98 miles the watch was reading 1.91 miles. Although for me the watch GPS measurement is much better than the AW 1 stand alone method of using the accelerometer I must admit to being disappointed. I could live with this small variance at shorter distances however when you go above 5 miles the variance would be too great. Anyone else have any GPS observations?
