Summary: Technically the Magellan will do what you want, but it's heavy, expensive and has an infuriatingly clunky interface that's simply hard work to use. If we were in the market for an OS mapping GPS at this price, we'd be looking at the Garmin Oregon 600 or the soon to launch Satmap Active 12.
Pros: Solid hardware, Ordnance Survey mapping, built-in camera, touch screen works with thin gloves.
Cons: Clunky interface, small screen, lacks wider connectivity, heavy.
Excerpt: The Explorist range marks the return of Magellan to the British outdoor market. There are three products in the range, with the 610 being the most suitable for hillwalkers as it has an electronic compass.
