eTrex H vs 255W

 

I have an Garmin eTrex H and a Garmin 255W. When I'm sitting with both and ask each for the coodinates I get two different results. They are several miles apart. How can this be and which is correct (the most accurate)?

format

My guess is that you have the coordinates set to two different formats, perhaps one to decimal degrees and one to degrees and minutes.

Map Datum

You may have the Etrex H set to a different Map Datum, but that should not make a difference greater than a few hundred yards.

How are you calculating the distance between the two points?
