Magellan's new rugged Triton line of handheld GPS navigators, ranging in price from $130 to $500, is designed for Daniel Boone types. All six models (the Triton 1500 is shown above) are compatible with National Geographic's TOPO! software packages ($100 each) that supply full topographical maps so you can see which hill you're on and how far away the next hill is so you don't end up like the Donner Party. If you do end up in dire straits, Magellan also has a deal with AAA for roadside assistance — assuming you can find a road. — Stewart Wolpin
