Philip's highly acclaimed Navigator sets the standard for British road atlases. With an ultra-large scale of 1.5 miles to 1 inch and over 300 pages of extra clear and up-to-date maps, it is up to four times as detailed as most other atlases. What makes the Navigator so different is that it shows even the smallest roads and lanes - including those that are often missed off less detailed mapping. For main roads and motorways every roundabout, junction and slip-road is shown in detail. In country areas thousands of individual houses and farms are marked and named, along with footpaths and tracks. These are all features you won't find in other road atlases of Britain. It includes an exceptional amount of tourist information - showing marinas, ferries, county showgrounds and many more tourist and leisure attractions. It also includes 50 detailed town and city plans, route-planning maps, a distances table and a 41,000 name index, making it second to none for motoring and general reference. The Navigator is widely used by professional drivers, by the emergency services and in national police training, and recommended in the motoring press and national newspapers.

Philip's Navigator South West includes Cornwall, Devon, Dorset, Somerset, Wiltshire and Gloucestershire.
