Another newbie, can you believe it. Got hooked by my bro-in law. Found 3 caches in North Carolina. I have been looking at everything I can find on GPS units. I don't need mapping, I have mapquest for that. Has anybody out there used the GPS60 and if so, how does it compare to, say the Garmin ETREX units. One thing that caught my eye was the type of antenna the GPS60 uses. I read that it can be accurate to 3 feet if held vertically. Any comments about this unit would be gratefully appreciated. Thanks!
