Golf Mode
Golf Mode is designed for golfers, offering features to assist with accurate distance measurement on the course.
- Flag-Lock with Vibration: When scanning for a flagstick, the rangefinder will vibrate briefly once it locks onto the flag, confirming the measurement. This helps distinguish the flag from background objects.
- Slope Compensation: This feature calculates the adjusted distance based on the incline or decline to the target, providing a "play as" distance. This can be toggled on or off via a dedicated switch or menu option (refer to display for indicator).

Hunting Mode
Hunting Mode provides essential information for hunters, including angle and horizontal distance.
- Angle Display: Shows the angle of inclination or declination to the target.
- Horizontal Distance: Displays the true horizontal distance to the target, which is crucial for accurate shot placement, especially when shooting from elevated positions.
