When you need a reliable compass for navigating and surviving in extreme conditions, consider the Suunto M-3 D/L Compass. A hardy baseplate compass, the M-3 D/L Compass features adjustable declination correction, and you can use it in low light conditions thanks to luminescent markings. The magnifying lens on the transparent baseplate makes it incredibly easy to use with a map, and metric and imperial scales give you options. Balanced for the northern hemisphere, the M-3 D/L Compass sports a high grade steel needle with jewel bearing and a liquid filled capsule for stable operation. To make it even easier to use, the M-3 D/L Compass has a detachable snap-lock lanyard with a wristlock that's easy to detach when you need to work with your map.
