Review via - 20th Sep, 2018 I like the explorer range, but oddly here there was some mismatch of a slither of boundary between explorer 155d and 156d. Some overlap would have helped. Bought as an aid to walking the Kennet and Avon canal. Had some problems navigating some paths in the surrounding area due to farmers blocking some routes. And non obvious paths across agricultural land. Makes me wonder if people are using GPS aids these days for these blind walks, or there are a lack of ramblers in Wiltshire walking them. I haven't tried their associated digital maps yet. But it did make me think that augmented digital versions - with landmarks such as trees and photos could really help.
