Performed the same test in the morning in a covered patio where I stay. Synchronized both watches, so almanacs were up-to date. First acquisition took the Ambit 3 about 7 sec's and the Fenix 3 more than 30 sec's. On subsequent acquisitions, the Ambit acquired location within 2-5 sec's while the F3 was nearly instant. But, the location shown by the A3 was very consistent while the F3 were all over the map. Re-did the test in the afternoon. This time both acquired locations within 5 sec's on initial acquisition. On subsequent acq's the A3 stayed within 2-5 sec's while the F3 was instant. However, again the F3 locations were not consistent, dispersing as far as 100m or more, while the A3 stayed within 10-20m dispersal.
