A pundit of digital technology recently argued that it is now no longer possible to make a movie like the Blair Witch Project, because GPS-enabled smartphones have rendered it nearly impossible to get lost, even in a deep forest. But, in reality, if you are exploring the wilderness, a smartphone is not your ideal companion, not least because it won't take it kindly if you drop it on a rock. A dedicated hiking GPS makes much more sense, but these have remained costly, for example Magellan's flagship eXplorist 710 comes in at just shy of £400. With the eXplorist 310, however, Magellan hopes to bring the base level down, whilst not compromising too much on features.
