TXBobcat,
According to Garmin's website, the 60CSX does have a Barometric altimeter. The unit I've got is the GPS Map76s and it's also got one. I hardley use it though, but I'm not in the mountains often, and don't have much of a use for it here in MO. One thing about the 60CSX, and the one that I've got is that you can put trails, roads, etc on a topo map if you get the topo map sofware. I've got some property in the Missouri Ozarks, and I've marked the property lines, along with roads, trails, and deer stands on the topo map. If I upgrade mine I've thought that I'd get the 60CSX, I don't know how it stands now, but from what I understand, at least when it first came out, it had the best & newest antenna so it would be more accurate, and would acquire the satelittes faster. Also, if you haven't got one yet, the cheapest place to get one is off the net. I've bought several from
www.tvnav.com and the first one I got, I ordered it before 9:00 am one day, and by 5:00pm the next I had it in my hands, and I didn't pay for next day delivery! Also, Geocaching is the best way to learn how to use the GPS!
