If you're planning on roughing it out in the woods anytime soon, there's already a plethora of rugged GPS options to keep you (somewhat) on track, but Satmap Systems' Active 10 handheld puts a new spin on trekking. The device is being dubbed the "world's first to offer fully integrated digital maps and GPS hardware," meaning that users can purchase additional map cards that include detailed imagery of counties, regions, national trails, and national parks. Additionally, the unit sports a 3.5-inch backlit color display, integrated patch antenna, Windows CE operating system, a multitude of power options, USB 2.0 connectivity, an SD card reader, ARM 9 processor, 128MB of RAM, SiRF Star III receiver, integrated media player, and an impact resistant waterproof enclosure to boot. Initially, the company will be offering maps of popular UK locales, but additional maps (including "international" zones) will purportedly be available in SD cards or potentially as internet downloads in the not too distant future. Satmap is currently accepting pre-orders for the Active 10, and while the unit is set to ship sometime this month, you can get on the waiting list now for £299.99 ($594).
