I bought two Pathfinder Guides last week, 'Kent' and 'Surrey & Sussex' as I thought my other walking guides for those regions were well out of date. I bought them about seven years ago and, in some places the landscapes have changed which makes some of the directions difficult to reinterpret.
However, they are still generally more accurate than these new Pathfinder Guides. We tried three different walks over the August Bank Holiday and were disappointed. Some of the directions you've published are factually wrong. For example, several times the Guide says take a right turn when it's in fact a left turn! These books were supposedly 'revised and reprinted in 2003'. The amount of changes to hedges, stiles, fences etc. - which are used in the Guides as landmark directions - are more than one year old!! These Guides have not been revised properly and in places are misleading. Consequently, the walks took longer than anticipated, and were much more stressful than need be. The OS maps printed in each guided walk worked well and it was very useful to cross reference, without them we would have been lost, literally.
