I purchased the 62st recently and took it out for a 9 mile geo caching adventure. While I like the unit very much in general, it has one major problem. Like any hiking GPS, the 62st will record your track as you hike, letting you upload it to your computer when you return home. This is very useful for keeping track of your adventures. The accuracy of the 62st's GPS , combined with its barometric altimeter, lets you accurately record your track for later use.
