Setup
Battery Installation and Charging
The PF2C rangefinder features a dual power supply system: a built-in rechargeable lithium battery and a CR2 lithium battery. The CR2 battery is typically pre-installed. To activate it, open the battery cover and remove any insulating plastic piece.
- CR2 Battery: Ensure the CR2 battery is correctly inserted. Remove the red insulating plastic piece if present.
- Rechargeable Battery: Connect the provided USB-C cable to the charging port on the bottom of the device and to a USB power source. The device will charge its internal 1000mAh battery. A full charge supports over 35,000 measurements.

Operating Instructions
The ACEGMET PF2C Golf Rangefinder is equipped with two main buttons: the Power/Measure button and the Mode button.
Powering On/Off and Measurement
- Power On: Short-press the Power/Measure button (marked with a star icon) to turn on the device.
- Single Measurement: Once powered on, short-press the Power/Measure button again to take a single distance measurement.
- Continuous Scan: Long-press the Power/Measure button to activate continuous scanning. Release the button to stop scanning. This is useful for scanning multiple targets or moving objects.
- Auto Power Off: The device will automatically power off after 16 seconds of inactivity to conserve battery.
Mode Selection
Short-press the Mode button (marked with 'M') to cycle through the available measurement modes:
- Flag Lock Mode: This mode is designed to quickly lock onto the flagstick, ignoring background objects. When the flag is detected, the device will vibrate and display the distance.
- Coach Mode: This mode assists in calculating distances from your ball to the pin. Measure the distance from your current position (ME) to the ball (P), then from ME to the pin (PI). The device will then calculate the distance from the ball to the pin, with slope compensation enabled.
- Scan Mode: Allows for continuous measurement as you pan across the landscape.
- Disc Mode: Specifically for Disc Golf players, this mode displays line of sight distance (LOS), elevation, and slope angle in feet.

Slope Function
The slope function provides adjusted distances based on elevation changes, which is useful for practice but may be prohibited in official competitions. To enable or disable slope:
- Locate the slide switch on the side of the device, near the logo.
- Slide it to reveal green for slope ON, or black for slope OFF.

Rain/Fog Mode
To activate or deactivate the rain and fog mode, press both the Power/Measure and Mode buttons simultaneously. An icon of a cloud with three raindrops will appear on the screen when this mode is active.
Brightness Adjustment
Long-press the Mode button to adjust the brightness of the display backlight. This allows for optimal visibility in various lighting conditions, from bright sunlight to low light.

Maintenance
- Cleaning the Lenses: Use the provided lens cleaning cloth to gently wipe the objective and eyepiece lenses. Do not use abrasive materials or harsh chemicals, as this can damage the optical coatings.
- Storage: When not in use, store the rangefinder in its portable soft case to protect it from dust, moisture, and physical impact.
- Battery Care: Recharge the internal battery regularly, especially if the device will not be used for an extended period. If using the CR2 battery, replace it when the low battery indicator appears.
- Avoid Extreme Conditions: Do not expose the rangefinder to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or CR2 insulating tab still in place. | Charge the internal battery using the USB-C cable. Check and remove the red insulating tab from the CR2 battery compartment. |
| Inaccurate measurements. | Lens obstruction, unstable hand, or measuring beyond range. | Clean lenses with the provided cloth. Ensure a steady hand. Confirm target is within the 5-1100 yard range. |
| Difficulty locking onto flag. | Background interference or flag too far. | Ensure Flag Lock Mode is active. Aim carefully at the flag. The flag-locking range is 5-350 yards. Try scanning mode for general distance. |
| Display is dim or hard to read. | Brightness setting is too low for current lighting. | Long-press the Mode button to adjust display brightness. |
