Suunto M-3 Compass

Magnetic dip causes compass needles to tilt toward the earth's poles. This compass is calibrated specifically for the Northern Hemisphere to ensure the needle remains level and moves freely, preventing it from dragging against the capsule housing.

No, this specific model is balanced for the Northern Hemisphere. Using it in the Southern Hemisphere will cause the needle to tilt and drag, leading to inaccurate readings and potential sticking.

The compass features an internal screw mechanism that allows you to offset the needle to account for the difference between true north and magnetic north. This lets you read your bearing directly from the map without having to manually add or subtract degrees every time.

Yes, it is quite practical for reading fine details on topographic maps, such as contour lines or small trail markers. It is integrated directly into the baseplate, so you don't need to carry a separate magnifying glass.

The luminescent markings are designed to glow after being exposed to a light source, such as a headlamp or flashlight. They are bright enough to help you orient your map or take a bearing in low-light conditions, though they will eventually fade over time.

The liquid inside the capsule acts as a dampener, which stabilizes the needle and prevents it from oscillating wildly. This allows the needle to settle quickly, making it much easier to take an accurate reading while you are moving.
