FAQs
What is declination and why is it important?
Declination is the angle between true north and magnetic north at your specific location. Setting the adjustable declination on your compass ensures that when you align the compass to magnetic north, it accurately reflects true north, making your map readings precise.
How do I use the sighting mirror for direction finding?
Hold the compass flat and extend your arm. Look through the sighting notch in the mirror towards your target. Rotate the compass housing until the north end of the needle aligns with the North mark inside the dial. Read the bearing indicated on the dial visible in the mirror.
Can this compass be used for signaling?
Yes, the reflective mirror can be used as a signaling device to attract attention by reflecting sunlight.
What does 'NH' mean in the product name?
'NH' typically refers to 'N'o 'H'umidity or 'N'o 'H'ydration, indicating it's designed for environments where moisture resistance is key, often implying it's not fully submersible but water-resistant.
What is a clinometer used for?
A clinometer measures the angle of a slope or incline. It's useful for assessing the steepness of hills, planning ascents or descents, and in mountaineering for avalanche risk assessment.
Is the Suunto MC-2 suitable for international travel?
Yes, the adjustable declination allows you to set it for different regions, making it suitable for international travel. The UTM scales are also widely used globally.
Troubleshooting
Compass needle is not pointing North accurately.
Ensure the adjustable declination is correctly set for your current location. Check for nearby magnetic interference from electronic devices, metal objects, or vehicles. Ensure the compass is held flat and level.
Mirror is scratched or clouded.
Gently clean the mirror with a soft, lint-free cloth and a mild lens cleaner. Avoid abrasive materials. If severely scratched, replacement might be necessary.
Clinometer is not functioning correctly.
Ensure the compass is held level when reading the clinometer. Obstructions or damage to the internal mechanism can affect readings; contact customer support if issues persist.
Luminous markings are not glowing.
Luminous markings require exposure to light to charge. Expose the compass to a strong light source (sunlight or flashlight) for a few minutes. The glow will fade over time and needs recharging.
Pros and Cons
Pros
- High precision for accurate navigation.
- Durable plastic construction for outdoor use.
- Versatile features including a clinometer and mirror.
- Luminous markings for low-light visibility.
- Adjustable declination for regional accuracy.
Cons
- May have a steeper learning curve for novice users.
- Plastic housing, while durable, might be perceived as less premium than metal alternatives.
- Requires understanding of declination for optimal accuracy.
Setup, Compatibility & Care
Setup:
- Adjust Declination: Locate the local magnetic declination for your area. Using a small screwdriver, adjust the declination scale on the compass to match your local value. Consult your local mapping agency or online resources for current declination values.
- Familiarize Yourself: Understand how to use the mirror for sighting, read the baseplate scales (if applicable), and utilize the clinometer.
Compatibility:
- The compass is designed for use with topographic maps featuring UTM grids. It is compatible with maps from various regions, especially those using the UTM system.
- It functions as a standard magnetic compass, aligning with the Earth's magnetic field.
Care:
- Cleaning: Wipe the compass with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, which could damage the plastic housing or scratch the mirror.
- Storage: Store the compass in a dry place, away from strong magnetic fields (like speakers or electronics) that could affect its accuracy. Ensure the needle is free to move and not locked against the housing.
- Protection: While water-resistant, avoid prolonged submersion. Protect the mirror from scratches.
