Garmin GPS III+
Yep, it is an oldie. but, it works well and I'm familiar with it.
Lindsay and I take it GEOCACHING and we took it on the last road rally we ran.
I use it snowshoeing as I have "misplaced" my truck a time or two.
It hooks into my laptop with MS streets and trips on it and works great. It also has seen use while WARDRIVING (locating wi-fi hot spots) using NetStumbler and other linux based tools.
It has favorite camping spots marked around the country from years of service. It has never let me down. It lacks fancy stuff like a color display and it only has what? a meg of writeable memory so you can't get the detail you can with today's units.
