Slope Compensation Mode
The rangefinder features a slope compensation mode that adjusts the measured distance based on elevation changes, providing a "play as" distance. This feature can typically be toggled on or off via a dedicated switch or button, making it suitable for both casual play and tournament use where slope features may be restricted.

Flag Locking with Vibration
To use the flag locking feature:
- Aim the rangefinder at the area around the flagpole.
- Press and hold the measurement button while slowly scanning across the flagpole.
- Once the rangefinder identifies and locks onto the flagpole, it will vibrate briefly, and the distance to the flag will be displayed. This feature is effective for targets up to 250 yards.
