Thanks for the reply but sold mine late last night off Craigslist locally. These are rock solid, very basic units. They came out over 10 years ago and while there are different modals of the eTrex, this basic yellow modal seems to be one that Garmin got right the first time. Its amazing in the technology world when you have a modal that lasts as long as this one has.
If you really want to get into geocaching with a handheld GPS, I would almost recommend spending a little more and getting something that syncs that syncs with geocaching.com a little easier. Running pocket queries and logging your find at the cache site is pretty sweet with a couple of the lower-end yet newer units. We purchased a Dakota 10 last year and because it is so much easier to load geocaches onto our GPS, and to log them right at the cache site, we found almost as many geocaches last year as we had in the previous 7 years!
