Magellan was a great explorer, and we know this because he has a penguin and some dots in the sky named after him. His expedition completed the first circumnavigation of the Earth, although he and all but 18 of the 237 men who set out didn't quite make it, most of them… well… dying. Still, if he had a GPS unit things would have turned out much better. Rumor has it he was offered one, but turned it down as "just a fad." Oh well.
If there's one thing more important than saving your own skin, it's competition. The rising popularity of the sport of geocaching has led the GPS company Magellan to produce a model of its eXplorist GPS tuned for the sport. The Magellan eXplorist GC has a preloaded database of geocaches all over the planet (as well as a worldwide basemap), it syncs with Geocaching.com GPX files and it includes a 30 day premium membership. The GC is rugged and IPX-7 waterproof, meaning immersion for 30 minutes at 1 meter. If that happens while geocaching something has gone horribly wrong.
Pop in two AA batteries, good for 18 hours, and you're staring at a 2.2 inch transflective screen that is very bright and easily readable in most situations, althought it would be nice if you could increase the font size a bit. The interface is streamlined for fast navigation; it would be even faster if it was a touch screen, but that would probably limit the weatherproofing and would definitely increase the price. There are plenty of features that increase the geocaching fun factor like a picture viewer, award tracker and walking compass.
The clip-in point at the bottom is not quite big enough for a carabiner, but you can loop cord or webbing through just fine. There are no topo maps, driving navigation or expandability in the unit, but that's all by design. Magellan designed the eXplorist GC specifically for geocaching, and for all but the most elite competitors it hits all the right notes at a very competitive price point.
