Sorry for a duplicate thread, but it i cannot see my original question on the first thread.
Here is the question:
I borrowed a friend's Garmin GPS 72 and tried my hand at geocaching. The problem is the gps will say I am 6 feet from object, then I take 2 steps and it says 40 feet from object. I go to where it says to go, then, 30 feet later I am back at my original location.
Today, I stood in 1 place and the gps readings 'moved around' while I was standing still. 5, 10, 30 feet movement witout me taking a step.
Very frustrating.
Is this the nature of gps? Is this because it is an older unit? Is it atmospheric (it was a beautiful clear day with a light tree canopy).
