The EENOUR Golf Laser Rangefinder comes with a built-in rechargeable lithium battery. Before first use, fully charge the device.
- Locate the USB Type-C charging port on the device.
- Connect the provided USB Type-C cable to the rangefinder and the other end to a USB power adapter (not included) or a computer USB port.
- The charging indicator light will illuminate during charging and turn off when fully charged. A full charge typically takes about 1.5 hours.
- Ensure the device is powered off during charging.
Figure 6.1: Charging the device via USB Type-C. The device offers approximately 20,000 measurements on a full charge.
6.2 Powering On/Off
- To power on: Press the Power Button (
) briefly. The display will activate. - To power off: Press and hold the Power Button for a few seconds, or the device will automatically power off after a period of inactivity to save battery.
6.3 Diopter Adjustment
Adjust the eyepiece to your vision for a clear view of the display and target.
- Rotate the diopter adjustment ring (located around the eyepiece) until the reticle and display appear sharp and clear.
7. Operating Instructions
The EENOUR Golf Laser Rangefinder offers several measurement modes to suit various golfing situations.
Figure 7.1: Control buttons and mode indicators.
7.1 Switching Measurement Units (Meters/Yards)
To switch between meters (m) and yards (Yd):
- With the device powered on, press and hold the Mode Button (
) for approximately 3 seconds. The unit will change.
7.2 Mode Selection
Press the Mode Button () briefly to cycle through the available measurement modes:
- Linear Distance Mode: Measures the direct line-of-sight distance to the target.
- Slope Mode: Calculates the slope-adjusted distance, which accounts for elevation changes. This mode is typically used for practice and not allowed in official competitions.
- Pin Lock Mode: Designed to easily lock onto the flagstick, ignoring background objects. The device will vibrate slightly when the flag is locked.
- 3-Point Measurement Mode: Allows you to measure the distance between three points, useful for calculating distances over obstacles or to specific areas.
7.3 Taking a Measurement
Once you have selected your desired mode:
- Aim the reticle at your target.
- Press the Power Button () briefly to take a single measurement. The distance will be displayed almost instantly.
- For continuous measurement (scan mode), press and hold the Power Button while sweeping across multiple targets. The distance will update in real-time.

7.4 "S" Switch (Slope Compensation On/Off)
The dedicated "S" switch allows for quick toggling of the slope compensation feature, making the device compliant for official tournaments when slope is off.
- Locate the "S" switch button on the side of the device.
- Press the "S" Switch (
) to toggle slope compensation on or off. - When slope compensation is off, an external LED indicator on both sides of the device will illuminate, signaling to others that the device is tournament legal.

8. Maintenance
Proper maintenance will ensure the longevity and performance of your rangefinder.
- Cleaning Lenses: Use the provided cleaning cloth or a soft, lint-free cloth to gently wipe the objective and eyepiece lenses. Do not use excessive force or abrasive materials, as this can scratch the lens coatings.
- Cleaning Body: Wipe the body of the rangefinder with a soft, damp cloth. Avoid using chemical cleaners, solvents, or strong detergents.
- Storage: When not in use, store the rangefinder in its dedicated carrying case to protect it from dust, dirt, and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: If storing for an extended period, ensure the battery is partially charged (around 50%) to prevent deep discharge. Recharge periodically if stored for very long durations.
9. Troubleshooting
If you encounter issues with your EENOUR Golf Laser Rangefinder, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the device fully using the provided USB Type-C cable. |
| Measurement is inaccurate or inconsistent. | Target is too far or too close; environmental factors (fog, rain); dirty lenses; unstable hold. | Ensure target is within measurable range (3-800m). Clean lenses. Hold the device steady. Avoid measuring through glass. |
| Display is blurry. | Diopter not adjusted; dirty eyepiece. | Adjust the diopter ring until the display is clear. Clean the eyepiece lens. |
| Cannot lock onto flag (Pin Lock Mode). | Too many background objects; flag is too small or far. | Try scanning slowly across the flag. Ensure the flag is clearly visible. |
| Device powers off unexpectedly. | Automatic power-off feature; low battery. | This is normal behavior to save battery. If it happens frequently, charge the device. |
