Here at BM we just love GPS devices, and this Satmap Active 10 is one hell of a device. What sets this apart from others is that it can handle Ordnance Survey Explorer and Landranger maps - that's the UK's 17 National Parks all available in 1:25,000 and 1:50,000 scale maps - all stored on compact SD cards. It's designed for the rigors of mountain biking too, with a rugged waterproof unit encasing the large colour screen with a replaceable screen protector.
£299 (1:25,000 Explorer and 1:50,000 Landranger Ordnance Survey maps are extra) www.satmap.com
