Strange distance errors? in How do I...? Posted January 6, 2008 Hubby bought me an eTrex for Christmas. It's only taken 2 years' worth of hinting We've got our first couple of finds under our belts, but are getting increasingly puzzled by the distance the unit is reporting. Today's walk was a linear; 1.7 miles out, 2.8 miles total travelled back at the car. Huh?! Similarly, we both happened to walk the same route at different times a couple of days ago. It said he'd done 2.6 miles; it told me 3 miles. I'd quite like to use the GPS instead of a pedometer to gauge how long I've walked, to save carrying multiple gadgets - but not until I figure out how we're confusing the poor thing! Any hints? Theories I'm mulling over: - It likes me better. Whilst I like this theory, it's not terribly useful - If we walk what it considers the same route, it only counts it once. - It needs constant access to the sky. I tend to hang it outside my clothing, he carries it in a pocket - but I'm not convinced by this either, as it's quite happy in the car. For both legs today, it was slung under my daughter's black wool coat. Thanks for any pointers! Nicky. The only thing I can think of right off is that maybe the unit does not have a clear view of the sky at all times. It could be obscured by heavy tree cover or maybe you are somehow shielding it from view at times, therefore it is not calculating the total distance. I know my unit will stop recveiving if I stick it in my pocket or walk into thick vegetation.
