Along with adjustable declination and a triple sighting system, the Alpin Sighting Compass has an unbreakable polished aluminum sighting mirror and a thermo-elastic, fluid-filled capsule. The Alpin Compass flexible capsule prevents bubbles that often occur with temperature changes and hairline cracks that appear after an accidental drop. The sighting mirrors solid metal housing and a durable ABS lid put up with trail abuse, while the built-in clinometer takes the guesswork out of slope measurement on ski tours. A luminous bezel makes readings easy on the eyes.
