Hi-Def GPS, a must for hikers more than 20 miles from anywhere

Summary: Seriously, it is not pretty, and can be hard to use at times, because of the meager menu system, but it is almost military grade in accuracy. No other gps I have seen even comes close. Usually I can be spot on or less than 5' off on any coordinates.
Summary: The Garmin GPS 12XL is exactly what I was looking for. I was not after a GPS unit that had stored maps, as in New Zealand there isn't that much mapping information available - hence I didn't go for the mapping GPS products. It is a sturdy, compact, and portable unit, only slightly larger than my cell phone (Nokia 6120). It fits easily and comfortably in my pocket. Battery life so far has been very good.
Summary: I bought this GPS a few years ago. As I work in the Army and my unit never fitted me with a military GPS, I decided to get one of my own. I was amazed then. It helped me out alot when trying to figure out my position. It's usefulness is limited in forests and in blizzards, which often is when you need the most. It was of course useless inside armored vehicles, but that's more than one can expect unless one has an external antenna.
Summary: I love this product! I used it in the High Arctic as a backup navigation tool while working as a mining exploration surveyor. Like all battery-powered equipment, the low-end temperature limitation is due to the batteries (4 alkaline AA's). It's portable, solidly made, not too heavy, and most importantly it tracks 12 satellites simultaneously to get a fast position fix.
