From their website :
Of course other devices, from the likes of Garmin and Magellan, do offer topographic mapping on their devices, but they’re cut down maps; the Active 10’s maps appear exactly as they do in paper format, and the familiarity this brings makes it incredibly easy to use.
It’s not all about the maps, however, because the Active 10 is a pretty impressive piece of kit in itself. It’s built around a 240 x 320 resolution colour LCD screen. The chassis is constructed from tough, rugged-feeling plastic. The screen is protected by a thick, clear and replaceable covering. The buttons have been made large enough to be operated while using gloves. And the whole thing is weather-proof with all slots, ports and compartments sealed with rubber flaps
