i have a garmin etrex and it works ok, i wouldn't be without it, but i get alot of bad signals need clear view of sky, my question is do the more expensive models have the same problem in pines, and when the leaves are still on. i dont want to spend the extra 200 on a better model if im gonna get the same results. i live in Pa. and others tell me its a problem they have too but usually only in Pa. for some reason Pa. doesn't like the sats. let me know what you use and how well it works for you.
