My Etrex is the basic model, its ok. I have a lot of trouble believing the posts of people that say their GPSr took them rite to the cache. I have had to do a lot of searching for all I have found. My gps tells me I'm anywhere from 1ft to 30ft away without moving. The first GPSr I bought was a Garmin GEKO but I took it back when I had to replace the batteries twice in one week and I only turned it on for maby 10 min. 3 times.
