Product Information
Full details
This National Geographic Compass is designed for adventurers and outdoor enthusiasts who need reliable direction finding. Its key benefit is providing accurate directional mapping with integrated measuring tools. A potential caveat is its primary focus on magnetic navigation, requiring user understanding of its functions for optimal use. The compass features a robust housing, a floating 360° scale with a north arrow, a sighting wire and slot for precise targeting, and integrated centimeter and measure scales.

FAQs
How do I use the sighting wire and slot?
Hold the compass close to your eye and look through the slot. Align the sighting wire with the distant object you wish to target. The direction indicated on the compass bezel when the wire is aligned is your bearing.
What is the purpose of the centimeter and measure scale?
These scales allow you to measure distances directly on a map (if the map scale is compatible) or to estimate distances in the field. The centimeter scale is for direct measurement, while the other scale might be for use with specific map scales.
How accurate is this compass?
The accuracy depends on proper use and the absence of magnetic interference. The floating 360° scale allows for precise readings of degrees. For true north, you may need to account for local magnetic declination.
Can I use this compass for advanced orienteering?
This compass is excellent for basic direction finding and map work. For advanced orienteering that requires specialized features like inclinometers or detailed surveying, other compass models might be more suitable.
How do I attach it to my backpack?
The compass has a small lug with a hole, designed for easy attachment to a snap hook or carabiner, allowing it to be secured to your backpack or gear for quick access.
What does the 'floating' scale mean?
The 'floating' scale refers to the liquid-filled capsule that contains the compass needle and degree markings. This damping mechanism allows the needle to settle quickly and reduces oscillation for more stable readings.
Troubleshooting
Compass needle is not pointing north accurately.
Ensure the compass is held flat and level. Move away from any metal objects, electronics, or large magnetic sources that could cause interference. Note that this is a magnetic compass and points to magnetic north, not true north. For precise navigation, magnetic declination adjustments may be needed.
The needle seems stuck or sluggish.
Gently tap the side of the compass to dislodge the needle. Check for any visible obstructions around the needle pivot. If the issue persists, the compass may have been damaged.
Sighting wire is bent or damaged.
Handle the compass with care to avoid damaging the sighting mechanism. If bent, it may be possible to gently realign it, but avoid excessive force. Significant damage may impair accurate sighting.
Pros and Cons
Pros
- Lightweight and portable for easy carrying.
- Durable construction suitable for outdoor use.
- Includes essential measuring scales for mapping.
- Sighting feature allows for precise targeting.
- Convenient attachment point for gear.
Cons
- Primarily a magnetic compass; requires understanding of magnetic declination for true north accuracy.
- May be too basic for advanced orienteering requiring specialized features.
- No built-in inclinometer or other advanced geological tools.
- Relies on a clear view for sighting features.
Setup, Compatibility & Care Instructions
Setup: This compass requires no setup beyond understanding its function. Ensure the needle can move freely. When using, hold the compass flat and level away from metallic objects that could interfere with the magnetic needle.
Compatibility: The compass is a standalone navigational tool and is compatible with maps and the natural environment. Its scale is compatible with standard map scales.
Care:
- Keep the compass clean using a soft, dry cloth. Avoid abrasive cleaners.
- Store in a cool, dry place, away from strong magnetic fields.
- Protect the sighting wire and scale from scratches.
- Ensure the needle pivots freely; if it sticks, gently tap the compass or check for obstructions.
