For those looking for navigational insight whilst trekking, Magellan's Triton 2000 should certainly fit the bill. Boasting a rugged, water submersible exterior, a two-megapixel camera, 2.7-inch QVGA touchscreen, digital compass, a barometer, built-in LED flashlight, and an SD expansion slot, this handheld GPS device even touts the ability to record and attach audio to waypoint files -- you know, so you can keep track of exactly how frantic you're getting as you venture off course. Furthermore, this gizmo is reportedly the first to offer "full, on-screen compatibility, usage, and display of National Geographic's maps," including its 28 TOPO! outdoor recreation mapping software titles that cover all 50 states. The Triton 2000 is slated to launch in North America next month and in Europe this October, and will retail for a stiff $499, but if you won't be needing all the niceties already mentioned, there's a full line of lesser-spec'd Triton devices on the horizon that are far more budget friendly.
