The SILVA Expedition Series is for experienced users and professionals. The Expedition series has been a global leader when it comes to accuracy, precision and durability for many years. The SILVA Expedition Series comes with two completely new features: a Slope card and a Scale lanyard. If the terrain demands for a mirror sighting compass Expedition S is your optimal companion. SILVA Expedition S features easy-handling Dryflex™ housing, silicon rubber feet for precision map work, detachable safety-release lanyards, night-enabling luminous markings, magnifying lens, map-measuring scales in mm or inches, 1:25,000, 1:50,000 and GPS scales – plus built-in adjusters for magnetic declination (including permanent local adjustment). The Expedition S can also map-measure 1:40,000 and it comes with a clinometer for measuring slope angle and 45-degree angle assistance on the mirror-sighting function. The mirror-sighting function is perfect when determining direction over longer distances. The slope card is great for detecting avalanche risk and to determine how challenging your journey will be. By knowing the slope you can also judge any extra distance that you need to go due to the slope. The scale lanyard has two scales on it; 1:25, and 1:50, which facilitates to measure the distance of your hike. Since it’s soft and bendable it’s easy to place it directly on to your route on the map. The new graphics contain a more distinct arrow (Expedition) and also a more contemporary font.
