Flag Lock is a crucial feature in golf rangefinders that helps players accurately measure the distance to the flagstick by filtering out background distractions. Here’s a step-by-step guide to using flag lock on rangefinder effectively:

1. Power On and Set the Mode

Turn on your rangefinder and ensure it is set to “Golf Mode” or “Flag Lock Mode,” depending on the model. Some advanced rangefinders also have a Slope Mode for adjusting elevation differences.

2. Aim Steadily at the Flagstick

Hold the rangefinder with both hands to minimize shaking and aim directly at the flagstick. For better stability, you can rest your elbows against your body.

3. Press and Hold the Measurement Button

Press and hold the power or measurement button to start scanning. The rangefinder will search for the closest target in its field of view.

4. Lock Onto the Flag

The device will detect and prioritize the flagstick while ignoring background objects like trees or hills. Some rangefinders may require you to move the crosshair slightly over the flagstick to confirm detection.

5. Receive Confirmation

Once the flag is locked, most rangefinders will provide haptic feedback (vibration), a visual indicator, or an audible beep to confirm a successful lock. The display will then show the exact distance.

6. Read and Use the Distance

Check the distance displayed and use it to select the right club for your next shot. If your rangefinder has Slope Adjustment, it will provide an adjusted yardage based on elevation changes.

Pro Tips for Better Accuracy:

• Use Pin-Seeking Technology (if available) to enhance flag detection.
• Scan multiple times if the flag doesn’t lock immediately.
• Avoid excessive hand movement for better precision.
• Use a rangefinder with stabilization features if you have shaky hands.
