2. Powering On/Off
Press the power button (usually located on the top or side) once to power on the device. The display will activate. To power off, either wait for the automatic shutdown or press and hold the power button (refer to specific device markings if available).
3. Unit Conversion

Operating Instructions
1. Basic Distance Measurement
The rangefinder offers a measuring range of 4 to 1000 yards with an accuracy of ±0.5 yards. It features 7X magnification and fully multi-coated glass lenses for a bright and clear view.
- Look through the eyepiece.
- Aim the crosshairs at your target.
- Press the power/measurement button once to get a reading. The distance will be displayed on the internal HD LCD.
2. Mode Selection (Slope Compensation)
The AquilaPro Mini4 offers multiple modes, including non-slope mode for straight-line distances and golf slope compensation mode for adjusted distances based on elevation changes.
- Non-Slope Mode: Provides the direct line-of-sight distance to the target. This mode is typically legal for tournament play.
- Golf Slope Compensation Mode: Calculates and displays the "play as" distance, accounting for uphill or downhill slopes. This mode is generally not permitted in sanctioned tournaments.
To switch between modes, press the 'MODE' button. A visual indicator (e.g., a slope icon or a blue light) on the device or display will confirm the active mode. The device features a slope toggle for tournament legality.

3. Intelligent Flagpole Locking with Vibration
This feature helps to lock onto the flagstick, ignoring background objects, and provides a physical confirmation once locked.
- While in measurement mode, aim at the flagstick.
- Press and hold the measurement button, slowly scanning across the flagstick.
- The device will vibrate briefly once it has successfully locked onto the flag, and the distance will be displayed.

4. Magnetic Mounting
The AquilaPro Mini4 is equipped with an upgraded magnet for secure mounting. This allows you to conveniently attach the rangefinder to metal surfaces, such as a golf cart frame, for easy access during play.

Maintenance
1. Cleaning
To maintain optimal performance and clarity, keep the lenses and body of your rangefinder clean.
- Use the provided cleaning cloth to gently wipe the lenses. Avoid using abrasive materials or harsh chemicals.
- For the body, a soft, damp cloth can be used. Ensure no moisture enters the device.
2. Battery Care
The built-in Lithium-Ion battery is designed for long life. To prolong battery health:
- Avoid fully discharging the battery frequently.
- Store the device in a cool, dry place when not in use.
- If storing for extended periods, charge the battery to approximately 50% every few months.
3. Storage
Always store the rangefinder in its protective hard shell case when not in use to prevent damage from impacts, dust, and moisture. The device has an IP54 waterproof rating, offering protection against splashes and dust, but it is not designed for submersion.
Troubleshooting
If you encounter issues with your AquilaPro Mini4 Rangefinder, please refer to the following common solutions:
- Device not powering on: Ensure the battery is fully charged. Connect the Type-C charging cable and allow it to charge for at least 30 minutes before attempting to power on again.
- Inaccurate readings: Ensure the lenses are clean. Make sure you are aiming at a clear target and not through obstructions. Check that the correct measurement unit (yards, meters, feet) is selected.
- Flag lock not working: Ensure you are in an appropriate mode for flag locking. Try scanning slowly across the flagstick. Ensure there are no strong reflective surfaces directly behind the flag that might interfere.
- Display is dim or unclear: Check battery level. Ensure lenses are clean. Adjust the diopter (if available) on the eyepiece for your vision.
If problems persist, please contact customer support for further assistance.
