[QUOTE="ChadRack, post: 20697, member: 90"] On your 12XL, switch from DMS format to UTM. The coordinates are now in meters. When you you go to the position page, you'll have a "Northing", that's for vertical, and an "Easting" for horizontal. Take an average position at point 1 and an average at point 2. Now take the difference between the vertical readings for 1 and 2, and the horizontal readings for 1 and 2. These give you the 'rise' and the 'run' for the triangle and you can now figure the 'diagonal' which will be the distance, in meters, between 1 and 2. If there is much difference in elevation between the two points, then you'll have to take this into account also. Just figure another triangle. Use the topo to find difference in elevation as GPS has some trouble with altitude. Your handheld unit is much more accurate than the .01 mile display. Some of the newer units switch to feet once you get close to your desired waypoint. This is nice, but not as accurate as averaging both positions. Hope this helps. [/QUOTE]
