Abstract

An improved range finder for use on a golf course. The improved range finder includes means for identifying the closest target in a field of view during a sweep operation of the field of view and means for presenting the distance of the closest target at the conclusion of the sweep operation of the field of view. The improved range finder preferably uses infrared light to detect a flagstick.

Claims (12)

1. A range finder for use on a golf course, the range finder comprising:

a housing:

a laser for emitting a laser beam to a flagstick to be measured;

a detector for detecting a reflected light from the flagstick;

an integrated camera for magnified optical viewing disposed within the housing;

a measuring part for calculating a distance to the flagstick on the basis of the reflected light detected by the detector;

means for variable magnification to acquire the target flagstick;

a signal processing software routine for recognizing an infrared signature of a flagstick and means for alerting a user of the range finder to the acquisition of the infrared signature of the flagstick;

means for identifying the closest target in a field of view during a sweep operation of the field of view and means for presenting the distance of the closest target at the conclusion of the sweep operation of the field of view;

means for changing a circular view to a narrow horizontal slit view of the flagstick during a sweep operation of the field of view; and

a display capable of displaying the flagstick and the distance to the flagstick.
