MIRROR SIGHTING FOR LONGER DISTANCES
This compass features a mirror that allows you to view the compass dial and the background at the same time. The fact that the compass dial can be seen at the same time the reference point is aligned makes mirror compasses more desirable for taking accurate bearings. A mirror-sighting compass is at its best in open terrain where you must determine direction over long distances.

SLOPE CARD
The slope card is great both for detecting avalanche risk and for determining how challenging your journey will be. By knowing the slope you can also judge any extra distance that you need to go due to the slope. Always take caution in steep terrain. The risk of avalanches increase if the slope is steeper than 30 degrees. The slope card will help you detect this risk.

SCALE LANYARD
This compass model is equipped with a detachable scale lanyard that works like a ruler. The scale lanyard has two scales on it; 1:25, and 1:50, which makes it easier to measure the distance of your hike. Since its soft and bendable it’s easy to place directly on to your route on the map when you are out in the terrain – or when you are planning for your next adventure.
