S.O.L Survive Outdoors Longer Map Compass

No, this specific model is balanced and calibrated exclusively for use in the northern hemisphere. Using it in the southern hemisphere will cause the needle to drag or tilt, resulting in inaccurate readings.

The liquid filling acts as a dampener, which stabilizes the needle and prevents it from oscillating wildly. This allows the needle to settle on the correct heading much faster, even while you are walking.

This compass features a fixed declination adjustment that allows you to set the offset between magnetic north and True North once. This ensures that your map readings are automatically corrected for your specific region, saving you from having to do the math manually in the field.

Yes, the integrated magnifier is designed to help you read fine details on topographic maps, such as contour lines, small trail markers, or elevation data, which can be difficult to see with the naked eye.

The luminescent needle and ring are designed to glow after being exposed to a light source, making them highly visible in low-light conditions or at dusk. However, they are not self-illuminating and will require occasional 'recharging' with a flashlight or headlamp to maintain brightness throughout the night.
