1. Introduction
The Proster Waterproof Hiking Compass is a robust and multi-functional navigation tool designed for outdoor enthusiasts, hikers, mountaineers, and campers. Featuring a durable metal construction, a fluorescent scale for low-light visibility, and an integrated clinometer, this compass provides reliable direction finding and slope measurement in various environments. Its waterproof and shockproof design ensures performance even in challenging weather conditions.

2. Product Features
- Durable Metal Construction: Strong material protects the dial plate and ensures longevity.
- Fluorescent Scale: Clear and easy-to-read markings that glow in the dark after absorbing enough sunlight, allowing for night navigation.
- Integrated Clinometer: Measures differences in height and slopes with a range of 0-90 degrees.
- Sighting Mechanism: Features a gun sight for locating direction and a sighting window with a sighting line for accurate readings.
- Plotting Scales: Includes a centimeters graduated scale and a plotting graduated scale for measuring distances on maps.
- Waterproof (IP65): Capable of working under extreme weather conditions; resistant to rain but not designed for submersion.
- Shockproof: Designed to withstand impacts and maintain functionality.
- High Accuracy: Floating compass dial with a 360° scale, offering a deviation of 1 degree or less.
- Luminous Magnet Arrow: For fast and easy reading.

5. Setup
- Unpack: Carefully remove the compass from its packaging and carry bag.
- Inspect: Check for any visible damage. Ensure the dial moves freely and the bubble level is intact.
- Familiarize: Open the compass fully. Identify the main components: the base plate with rulers, the sighting mirror/cover, the compass dial, the clinometer, and the sighting mechanism (gun sight).
- Charge Fluorescent Scale: Expose the compass to natural light or a strong artificial light source for a few minutes to activate the fluorescent markings for night use.
6. Operating Instructions
6.1 Basic Direction Finding
- Hold Level: Hold the compass flat and level in your hand or on a stable surface. Ensure the bubble in the gradienter (bubble level) is centered.
- Orient North: Allow the magnetic needle to settle. The red end of the needle typically points North. Rotate the compass body until the 'N' (North) on the dial aligns with the red end of the magnetic needle.
- Read Bearing: Once oriented, you can read the bearing of your desired direction from the compass dial.
6.2 Using the Sighting Mechanism
- Open Fully: Open the compass cover (sighting mirror) to a 90-degree angle.
- Align Sight: Look through the sighting window (rear sight) and align the front sight (gun sight) with your target object.
- Read Bearing: While keeping the sights aligned with the target, observe the compass dial through the sighting mirror. The reading indicated by the spider line on the mirror is the magnetic bearing to your target.
6.3 Using the Clinometer (Slope Measurement)
- Position Compass: Hold the compass on its side, aligning the base with the slope you wish to measure. For best accuracy, place it on a flat surface that is parallel to the slope.
- Read Scale: The internal pendulum or needle of the clinometer will indicate the angle of inclination (slope) on the graduated scale (0-90 degrees).
6.4 Measuring Distance with Plotting Scales
- Identify Scale: Use the centimeters graduated scale (0-15 cm) or the plotting graduated scale (e.g., 1:25000, 1000, 2000, 3000 meters) on the sides of the compass.
- Align with Map: Align the appropriate scale with the distance representation on your map.
- Read Distance: Read the distance directly from the scale, converting it based on the map's ratio if necessary.

7. Maintenance
- Cleaning: Wipe the compass with a soft, damp cloth. Avoid harsh chemicals or abrasive materials that could scratch the surface or damage the fluorescent markings.
- Storage: Store the compass in its provided carry bag when not in use to protect it from scratches and impacts. Keep it away from strong magnetic fields (e.g., magnets, speakers, electronic devices) which can demagnetize the needle or cause inaccurate readings.
- Water Exposure: While waterproof (IP65), avoid prolonged submersion in water. If it gets wet, dry it thoroughly before storing.
- Temperature: Avoid exposing the compass to extreme temperatures for extended periods, as this can affect its accuracy and material integrity.
8. Troubleshooting
- Inaccurate Readings:
- Ensure you are holding the compass level and away from any magnetic interference (e.g., metal objects, electronic devices, power lines).
- Check if the needle is sticking. Gently tap the compass to free it. If it continues to stick, the pivot might be damaged or dirty.
- Fluorescent Scale Not Glowing:
- The scale needs to be 'charged' by exposure to light. Expose it to bright light for several minutes before use in dark conditions.
- Bubble in Clinometer Not Centered:
- Ensure the compass is on a perfectly flat and stable surface when checking the bubble level.
9. User Tips
- Practice Regularly: Familiarize yourself with all functions of the compass, especially before heading out on a trip. Practice using it with a map in a known area.
- Declination Adjustment: While this compass does not feature a built-in declination adjustment, remember to account for magnetic declination in your area when navigating with a map. Magnetic North and True North are not the same.
- Protect from Extreme Cold: In very cold temperatures, the liquid inside the compass can become sluggish, affecting needle movement. Keep the compass close to your body to keep it warm if possible.
- Use the Carry Bag: Always use the provided carry bag to prevent scratches and damage during transport.
