Yes, that's what it means. If you keep zooming in you will see a circle, which indicates the 25 feet of accuracy, and you would be some where in it. That's normal accuracy, on a good clear day you may see 11 feet or 16 feet, it depends on how many satellites your receiver can "hear". If you watch on the satellite screen, the accuracy will continue to improve as each sat. logs into the receiver. Get behind a hill and you might drop a few sats.
Imagine a circle or ring, and think of that as a satellite. When the second satellite is received, the small intersection where the 2 rings overlay would indicate you are some where in the oblique. Add another circle and the oblique gets smaller. Each satellite or ring that gets overlaid makes the area smaller, or more accurate.......
There is a ton written on how gps works.....a good place to start is usgs.gov.....then search their site for gps.
I went to the UBGF national run off this weekend. Beagle clubs are usually in the middle of no where, drove right to it with the gps. I get a little ragging from my friends about it, but after a trip like this one where I was able to show some of them how it really worked, and how simple it is, all they could say is "I've got to get one of those"......sure beats driving the back roads all night with out a clue.......enjoy!
