Silva compasses are recognised as being of the highest quality; teams using their compasses made a clean sweep of medals at the 1997 World Orienteering Championships. The Walker model is a very accurate and high class navigational tool ideal for fast and exact map work. Luminous points for night navigation, red/black North-South lines, rounded corners on base plate and three silicon feet to prevent the compass sliding off the map. Stencil holes for exact position markings on the map and magnifying lens. Scales marked in mm and inches, romer scales 1:25 000, 1:50 000 and 1:63 360.
