Menu item Rangefinder allows you to set up built-in rangefinder’s parameters as follows:
Function "TPA" allows you to change the angle of target location (angle of elevation). When the function is activated, the angle is shown continuously. When the function is disabled, the angle is shown if the rangefinder is working. The angle is shown in a pop-up menu during measurement.
"THD" function allows you to measure true horizontal distance to a target based on the angle of elevation value.
