Silva Expedition S Compass

For navigators who demand accuracy in serious terrain, the Silva Expedition S represents the standard that professionals and experienced backcountry travellers have relied on for decades, now with two genuinely useful new additions.

The Slope Card and Scale Lanyard are the headline upgrades. The Slope Card lets you measure incline angles directly, which is critical for avalanche risk assessment in Canadian mountain terrain and for planning realistic daily distances when vertical gain is a factor. The Scale Lanyard is soft and bendable with 1:25,000 and 1:50,000 scales printed on it, so you can lay it directly along your route on the map for quick, accurate distance measurement without reaching for a separate tool. Combined with the compass's existing 1:25,000, 1:50,000, 1:40,000, and GPS scales plus mm and inch measurements, this is a complete navigation package in one instrument.

The Dryflex housing is grippy and durable in wet and cold conditions, silicon rubber feet hold the compass steady on a map without slipping, and the mirror sighting system with 45-degree angle assistance allows precise bearing work. Luminous markings keep the dial readable after dark, and the built-in magnetic declination adjuster with permanent local setting means you're not manually correcting every time you pull it out. Detachable safety-release lanyards are included.
