Flag Lock with Vibration (Scan Mode)
This mode is ideal for quickly and accurately locking onto the flagstick, even with background objects. The device provides a vibration feedback when the flag is successfully locked.
- While looking through the eyepiece, press and hold the Power button.
- Slowly scan from a point beyond the flag towards the flagstick.
- The rangefinder will identify the closest target (the flag) and vibrate, displaying its distance. A scan sign will appear in the upper right corner of the display.

Slope Switch Function
The slope function calculates the adjusted distance based on elevation changes, providing a more accurate 'play as' distance. For golf tournaments, this function can be easily turned off.
- To toggle the slope function on or off, press and hold the 'M' (Mode) button for approximately 5 seconds.
- The display will indicate whether the slope function is currently active or deactivated.
