Suunto MC-2 G Mirror Compass

The 'G' stands for globally balanced. This means the needle is designed to function accurately anywhere in the world, unlike compasses balanced specifically for the Northern or Southern Hemisphere.

A mirror compass allows you to sight a landmark and read the bearing simultaneously, which significantly increases accuracy. The mirror also doubles as a signaling device in emergency situations.

Yes, the integrated clinometer is straightforward. You simply hold the compass at eye level and tilt it until the clinometer needle aligns with the desired angle on the scale, making it very useful for assessing avalanche risk or terrain steepness.

Yes, the compass features luminescent markings on the bezel and needle. You will need to 'charge' them briefly with a flashlight or headlamp, but they provide sufficient visibility for night navigation.

There is a small adjustment screw on the back of the capsule. Using the provided tool, you can rotate the inner scale to account for the difference between true north and magnetic north in your specific location, allowing you to read map bearings directly without manual calculation.

A standard compass needle can stick or drag if held at an angle. The 20-degree tilt margin allows the needle to remain stable and accurate even if your hand isn't perfectly level, which is a common occurrence when navigating rugged terrain.
