- Mode Button: Used to cycle through different measurement modes.
- Power/Start Button: Powers on the device and initiates measurement.
- Objective Lens: The front lens through which the laser is emitted and received.
- Laser Receiver Lens: Receives the reflected laser beam.
- Slope Switch: Toggles the slope compensation feature on or off.
- Built-in Charging: USB Type-C port for recharging the internal battery.
- Rotary Focusing: Adjusts the eyepiece for clear viewing.
- Eyepiece: The lens you look through to view the target and display.
Setup
1. Initial Charging
Before first use, ensure the rangefinder is fully charged. Connect the provided USB Type-C cable to the charging port on the device and to a compatible USB power source. The charging indicator will show the status. A full charge supports approximately 30,000 uses.

2. Adjusting Focus
Rotate the eyepiece (rotary focusing ring) until the display and target appear clear and sharp. This ensures optimal viewing and accurate measurement.
Operating Instructions
Power On/Off
Press the Power/Start Button once to power on the device. The device will automatically power off after a period of inactivity to conserve battery.
Switching Measurement Units (Yards/Meters)
While the device is powered on, press and hold the Mode Button for approximately 3 seconds to switch between Yards (Y) and Meters (M).
Measurement Modes
Press the Mode Button repeatedly to cycle through the available measurement modes:
- Straight Distance Mode (Mode 1): Measures the direct line-of-sight distance to the target.
- Golf Flag Locking Mode (Mode 2) with Vibration: Designed for golf, this mode helps lock onto the flagpole. Once locked, the device will vibrate to confirm the measurement. Supports distances up to 150 yards for flagpole locking and 300 yards for general flag distance.
- Slope Compensation Mode (Mode 3): When the slope switch is ON, this mode calculates and displays the adjusted distance, taking into account the incline or decline to the target. This provides a more accurate 'plays like' distance for golf.
- Horizontal and Height Ranging Mode (Mode 4): Measures both the horizontal distance and the vertical height difference to the target.
- Speed Measuring Mode (Mode 5): Measures the speed of a moving object.
- Continuous Scan Measurement Mode (Mode 6): Allows for continuous scanning of multiple targets to get distances quickly.
Using Slope Compensation
The FR20 features a physical slope switch. Slide the switch to the ON position to enable slope compensation. When enabled, the device will provide an adjusted distance that accounts for elevation changes, which is crucial for accurate club selection in golf. For tournament play, ensure the slope switch is in the OFF position to comply with rules.

Flag-Lock with Vibration
In Golf Flag Locking Mode (Mode 2), aim the crosshairs at the flag. The device will intelligently lock onto the flag, ignoring background objects, and provide a short vibration to confirm the measurement. This ensures you get the precise distance to the pin.

7X Magnification
The 7X magnification allows for clear and precise targeting of objects at long distances. Use the rotary focusing to ensure the image is sharp.

Maintenance
- Cleaning: Use the provided cleaning cloth to gently wipe the lenses. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth, not directly to the lens.
- Storage: Store the rangefinder in its carrying case when not in use to protect it from dust, dirt, and physical damage. Keep it in a cool, dry place.
- Water Resistance: The device is IP54 waterproof, meaning it is protected from dust and splashing water from any direction. Avoid submerging the device in water.
- Battery Care: Recharge the battery regularly, even if not frequently used, to maintain battery health. Avoid completely draining the battery for extended periods.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery; device malfunction. | Charge the device fully. If problem persists, contact customer support. |
| Inaccurate measurements. | Unstable aiming; dirty lens; incorrect mode. | Ensure stable aiming. Clean lenses. Verify correct measurement mode is selected. |
| Display is blurry or foggy. | Eyepiece not focused; condensation; dirty lens. | Adjust the rotary focusing ring. Allow device to acclimate to ambient temperature if moved from cold to warm environment. Clean lenses. |
| Flag-lock not working. | Not in Flag Locking Mode; flag too far or obscured. | Ensure Mode 2 is selected. Ensure flag is within range (up to 150 yards for lock) and clearly visible. |
