SatMap Active 10 GPS
Putting Ordnance Survey maps on a GPS device would seem to be the obvious solution to the gadget hound's mapping problems but such a device has only been on the market for just over a year. "These SatMap units are totally simple to use, rugged and take SD cards (bought separately) that cover different regions of the UK," Ed says. "It means you can follow your exact progress using familiar OS maps as a guide, instead of the demanding and sometimes vague instructions of other hiking GPS units."
