Silva Expedition Baseplate Compass - Professional Grade Navigation

Whether you’re navigating the dense fog of the South Shore or plotting a course through the thick woods of the highlands, GPS is great until the batteries die or the signal drops. The Silva Expedition is the gold standard in analog reliability—an "expert-level" baseplate compass designed for those who take their navigation seriously. It’s not just a pointer; it’s a precision tool kit for your map. Featuring a built-in clinometer for measuring slopes, a magnifying lens for fine map detail, and a unique scale lanyard that lets you measure your route as easily as laying down a piece of string, it turns "finding your way" into a science. It is the ultimate insurance policy for your backcountry kit, ensuring you always have a clear path home, regardless of the terrain or the tech.

• Advanced Navigation Toolkit: Includes a slope card and a clinometer to help you judge terrain difficulty and measure slope angles—essential for both route planning and safety in steep areas.
• Scalable Distance Lanyard: The detachable lanyard is soft, bendable, and marked with 1:25 and 1:50 scales, allowing you to measure the actual curves of your trail directly on the map.
• Precision Map Work: Silicon rubber friction feet prevent the compass from sliding on your map, while the integrated magnifying lens helps you spot the smallest contour lines and landmarks.
• All-Hours Reliability: Features luminous markings that stay visible for up to 4 hours after light exposure, making night navigation or low-light woods travel much safer.
• Global Accuracy: Equipped with a permanent magnetic declination adjuster, so you can set it once for your local area and read true north directly from the dial without doing manual math.
