4. Setup and Initial Use
4.1 Charging the Device
The rangefinder comes with a built-in 800mAh lithium battery. Before first use, ensure the device is fully charged.
- Connect the provided Type-C USB charging wire to the charging port on the rangefinder.
- Connect the other end of the USB cable to a suitable USB power source (e.g., computer, wall adapter).
- The charging indicator light will show red while charging and turn green once the battery is fully charged.

4.2 Powering On/Off
To power on the device, press the "ON/OFF" button. To power off, press and hold the "ON/OFF" button, or the device may automatically power off after a period of inactivity to conserve battery.
4.3 Adjusting the Eyepiece
Rotate the adjustable eyepiece to focus and achieve a clear image for your vision.

4.4 Switching Measurement Units (Meters/Yards)
To switch between meters (M) and yards (Y), press and hold both the "ON/OFF" and "MODE" keys simultaneously.

4.5 Magnetic Attachment
The rangefinder features an integrated magnetic stripe. This allows you to securely attach it to metal surfaces, such as a golf cart bar, for easy access during use.

5. Operating Modes
The BOBLOV 3M02 offers several measurement modes to suit different needs:
5.1 Range Mode
This is the standard mode for measuring linear distance to a target. Point the rangefinder at your target and press the measurement button to get the distance. The device provides 6X magnification for clear targeting.

5.2 Speed Mode
Use this mode to measure the speed of a moving object. Follow the object with the rangefinder while pressing the measurement button.

5.3 Flag Lock Mode
Specifically designed for golf, this mode helps you easily target and lock onto the flagpole. The device will vibrate to confirm that it has locked onto the flag, ignoring background objects.

5.4 Golf Distance Correction Mode (Slope)
This mode calculates the slope-adjusted distance, providing a more accurate "play as" distance for uphill and downhill shots. It accounts for elevation changes to give you a better understanding of the effective distance.

5.5 Other Measurement Modes
The rangefinder also supports:
- Manual Mode: Basic point-and-shoot distance measurement.
- Height Measurement: Calculates the height of an object.
- Angle Measurement: Measures the angle to a target.
- Scanning Measurement: Allows continuous measurement as you pan across multiple targets.
