Setup
- Unfold the Compass: Open the metal lid completely until it locks into position. Extend the sighting wire (front sight) and the thumb loop (rear sight).
- Attach Lanyard: Secure the lanyard to the designated loop on the compass for easy carrying and to prevent loss.
- Calibrate Fluorescent Elements: For optimal night visibility, expose the compass dial and magnet arrow to a strong light source (e.g., sunlight or flashlight) for several minutes to charge the fluorescent material.
Operating Instructions
1. Basic Navigation and Sighting
- Hold Level: Hold the compass firmly and level, ensuring the floating dial can rotate freely.
- Orient to North: Allow the magnetic needle to settle, indicating magnetic north.
- Take a Bearing:
- Look through the sighting lens (rear sight) and align the sighting wire (front sight) with your target.
- Read the bearing directly from the compass dial through the sighting lens. The vertical lubber line within the lens helps ensure accuracy.
- Adjust Prism Lens: If the numbers are blurry, adjust the prism lens for clear readability.

2. Using the Clinometer
The clinometer allows you to measure angles of elevation or depression, useful for determining slope gradients or heights of objects.
- Locate the clinometer scale on the side of the compass.
- Hold the compass vertically, aligning the base with the horizontal plane.
- Sight through the compass towards the top or bottom of the object you wish to measure.
- Read the angle indicated by the clinometer needle. The range is 0-90°.

3. Utilizing Fluorescent Features (Night Use)
The compass features fluorescent markings for use in low-light conditions.
- Before night use, expose the compass to a bright light source (sunlight or artificial light) for at least 10-15 minutes.
- The absorbed light will cause the dial and magnet arrow to glow, allowing for clear readings in the dark.

4. Plotting Scale
The compass includes a plotting scale for measuring distances on maps.
- The compass features a centimeter graduated scale and a plotting graduated scale (e.g., 1:25000, 1:50000).
- Align the appropriate scale with the map's scale to measure distances accurately.

Maintenance
- Cleaning: Wipe the compass with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the compass in its protective pouch when not in use to prevent scratches and damage. Keep it away from strong magnetic fields, which can demagnetize the needle.
- Water Resistance: The compass is IP65 rated, meaning it is protected against dust and low-pressure water jets. It can be used in rain but should not be submerged in water.

Troubleshooting
If you encounter issues with your compass, consider the following:
- Inaccurate Readings: Ensure you are away from strong magnetic fields (e.g., power lines, metal objects, electronic devices) that can interfere with the compass needle.
- Sticking Needle: Gently tap the compass to dislodge the needle if it appears stuck. Ensure the compass is held perfectly level.
- Faint Fluorescent Glow: Re-expose the compass to a bright light source for a longer duration to recharge the fluorescent material.
