Operating Instructions
1. Adjusting Focus
Rotate the eyepiece to adjust the focus until the display and target appear clear.
2. Changing Measurement Units (Yards/Meters)
To switch between yards (Y) and meters (M), long press the Mode button until the unit changes on the display.
3. Mode Selection
The BL-X3 Rangefinder offers two primary scanning modes. Press the Mode button briefly to cycle between them:
Mode 1: Continuous Scan (Tournament Legal)
This mode provides continuous distance readings as you scan across multiple targets. It is suitable for quickly assessing distances to various points on the course and is legal for tournament play as it does not include slope compensation.
- Select Mode 1.
- Press and hold the Power button while sweeping the rangefinder across your desired targets.
- The display will update with real-time distances.

Mode 2: Slope Distance, Angle, Flag-Lock with Vibration
This mode is ideal for daily training and provides advanced measurements including slope-adjusted distance and angle. The Flag-Lock feature helps to isolate the flagstick from background objects, and vibration confirms target acquisition.
- Select Mode 2.
- Aim the crosshairs at the flagstick or desired target.
- Press the Power button briefly. The device will vibrate once the flag is locked, and the display will show the actual distance, slope-adjusted distance, and angle.

Maintenance
1. Cleaning
Use the provided cleaning cloth to gently wipe the lenses and the body of the rangefinder. Avoid using abrasive materials or harsh chemicals that could damage the optics or casing.
2. Water Resistance
The BL-X3 is designed to be water-resistant (IP54 rated), meaning it can withstand splashes and light rain. It is not intended for submersion in water. Ensure the USB port cover is securely closed to maintain water resistance.
3. Storage
When not in use, store the rangefinder in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. This helps protect the device from dust and physical damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or device won't power on. | Low battery. | Charge the device using the provided USB cable. |
| Inaccurate distance readings. | Dirty lenses, target too far, or environmental factors (e.g., heavy fog, bright sunlight). | Clean lenses with the cleaning cloth. Ensure target is within range (5-1200 yards). Avoid use in extreme weather conditions if possible. |
| Cannot lock onto flag. | Shaky hands, small target, or background interference. | Use a steady hand. Try continuous scan mode (Mode 1) or sweep slowly around the flag in Mode 2 to help the flag-lock feature engage. |
