I found the following observation interesting. This past Saturday, while on an 11 mile hike I spoke with a fellow that was comparing his GPS to his father's GPS. Both were Garmin models I think. He found the relatively new devices did not report the same position or time. I asked about the time difference and he indicated his last observation yielded almost a two minute difference. I doubt this was due to mutual interference between the devices. I can not provide any more detail than given. I recall early GPS devices commonly displayed times that differed by as much as three or four minutes. The usual explanation was displayed position was given the programming priority and time was updated when convenient. I assumed this changed and today's GPS devices would be much better. Anyone aware of documented comparsions of common GPS units available today?
