SILVA Expedition S Compass | Professional Mirror Sighting & Avalanche Slope Card

Navigate the world’s most demanding terrain with total confidence using the SILVA Compass Expedition S. Specifically engineered for experienced outdoor professionals, search and rescue teams, mountaineers, and advanced backcountry navigators, this heavy-duty mirror-sighting compass sets the global benchmark for accuracy, durability, and technical land navigation.

Advanced Cartographic Precision & Handling

The Expedition S is built from the ground up to interface seamlessly with tactical and recreational topographic maps (such as 1:25k or 1:50k Ordnance Survey and National Geographic datasets). It features a tactical, easy-handling Dryflex™ rubber housing for all-weather grip, alongside integrated silicon friction feet on the baseplate to prevent slipping during precise map analysis.

Revolutionary New Navigation Features:

• The SILVA Slope Card: A critical backcountry safety asset. This specialized tool allows you to accurately calculate slope angles on your map to detect avalanche risk zones and gauge the physical difficulty of your route. By accurately measuring the incline, you can precisely judge the true ground distance required to conquer steep slopes.

• The Soft Scale Lanyard: Ditch the rigid rulers. This innovative, bendable distance lanyard features dedicated 1:25 and 1:50 scales directly on the fabric. Because it is soft and flexible, you can bend it directly over twisting trails, switchbacks, and river corridors on your map to get a rapid, highly accurate true-distance reading of your planned hike.

Expert Sighting, Declination & Engineering:

• Mirror Sighting System: Engineered with a tactical sighting mirror and target hole, allowing you to take ultra-precise bearings along distant horizons or peaks while simultaneously tracking the compass capsule. Features integrated 45° angle assistance for complex sighting grids.

• Permanent Declination Adjustment: Includes a built-in mechanical adjuster for local magnetic declination, allowing you to set it once and permanently offset the variance between True North and Magnetic North.

• Built-in Clinometer: Features a mechanical pendulum clinometer inside the fluid capsule to measure real-time vertical slope gradients while out in the field.

• Night Navigation: Outfitted with high-intensity luminous markings that are activated by light for flawless, low-visibility or night-enabling orienteering.

• Friction-Free Accuracy: Utilizes a premium sapphire jewel bearing to ensure smooth, lightning-fast, and friction-free movement of the compass needle.
