The SATMAP SD Card fits into the SATMAP Sports GPS Unit, to give specific area coverage in 1:25k and 1:50k of Ordnance Survey Data.

Traveling from what was the original capital of England, Winchester, and running along the chalk escarpment of the South Downs to the white cliffs' Seven Sisters and Beachy Head at Eastbourne, this trail covers some of the most beautiful lowland routes in the country.
It takes in numerous attractive villages and woodlands, and is rich in history as the path follows a route that has been traveled since the end of the Ice Age.
