Measurement Modes
- Single Ranging Mode: Measures the straight-line distance to a single target.
- All-in-one Mode: Provides angle, height, and horizontal distance measurements simultaneously.
- Scan Mode: Allows continuous scanning of multiple targets to get distances quickly.
- Two-Point Height Measurement Mode: Measures the height between two points.
- Speed Measurement Mode: Calculates the speed of a moving object.
- Golf Mode: Specifically designed for golf, offering:
- Flagpole Lock with Vibration: The device vibrates to confirm when it has locked onto the flagpole, ignoring background objects.
- Slope Compensation: Automatically calculates the elevation difference and provides an adjusted distance for uphill or downhill shots.
- Angle Switch: Manually enable or disable the slope compensation feature as required by golf rules.
- Data Storage Function (NK-1000): Stores measurement data for later review.
4. Maintenance
- Cleaning Lenses: Use a soft, clean cloth specifically designed for optical lenses. Avoid abrasive materials that could scratch the lens.
- Storage: Store the rangefinder in its protective carrying case when not in use. Keep it in a dry, cool place away from direct sunlight and extreme temperatures.

5. Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect to a USB power source and allow it to charge for at least 30 minutes before attempting to power on again.
- Inaccurate readings: Ensure the lenses are clean and free from smudges. Make sure there are no obstructions between the rangefinder and the target. Check that the correct measurement mode is selected for your application.
- Display unclear/blurry: Adjust the eyepiece focus ring until the display is sharp.
- Unit not switching (M/Y): Ensure you are pressing and holding both required buttons simultaneously for 3-5 seconds.
