GPS wierdnesses
Posted: Jun 07 2008 3:21 pm
I'm wondering if anyone with a GPS knows why I had such a bad experience with one I borrowed yesterday. I'm in the market for buying one, and a friend allowed me to test his ... is was a Garmin eTrex.
I used it when hiking First Water to Battleship Mountain. The first 3.5 miles were fine, and then all of the sudden I looked down (maybe a minute later) and it said I had gone 17 miles, and that my max speed had jumped from 4mph to 47.1mph.
I'm honestly not the Dash or Flash Gordon or anything. ;)
From that point on, the reliability of the data was spotty. It never developed a consistent trail from the hike, and on the way back some of the tracking back to the waypoints I created worked...and then others said weird things like 22 miles to the next waypoint that I knew was 1-3 miles away.
Was it just a defective device, or do just GPS's do that sometimes and I just had bad luck? I'm actually now looking into getting a Magellan Triton 500, but any help anyone could give me on this would be much appreciated!
