Silva Expedition Compass

For experienced navigators who demand professional-grade accuracy from a traditional baseplate compass, the Silva Expedition delivers the full toolkit in a refined, updated package that has set the global standard for serious compass work for decades.

The two newest additions, the Slope Card and Scale Lanyard, address real field needs. The Slope Card measures incline angles for avalanche risk assessment and route planning in mountainous terrain, an essential tool for anyone travelling in Canadian backcountry snow country where slope angle is a life-safety consideration. The soft, bendable Scale Lanyard with 1:25,000 and 1:50,000 scales lays directly along your route on the map for fast, accurate distance measurement without reaching for a separate tool.

The rest of the feature set represents decades of refinement. Dryflex housing grips securely in wet and cold conditions, silicon rubber feet hold the compass stable on a map without slipping during precise work, and the built-in clinometer measures slope angles directly. Permanent magnetic declination adjustment means your local setting stays dialled in without resetting. A sapphire jewel bearing delivers friction-free needle movement, and the magnifying lens handles fine map detail. Luminous markings cover low-light navigation. If the terrain calls for sighting over long distances, the Expedition S adds mirror sighting capability to this same feature set.
