ABSTRACT:
A golfing apparatus determines the carrying distance of a golf ball which has a golfer has struck and includes a speed measuring mechanism, either an acoustic trigger or an optical trigger, a correlator and a display. The speed measuring mechanism has a boresight disposed at angle in the range of zero degrees to twenty five degrees with respect to level ground so that it can be aimed at the struck golf ball while in flight. Either the acoustic trigger or the optical trigger is electrically coupled to the speed measuring mechanism and turns on the speed measuring mechanism in response to either the sound of the struck golf ball or the sight of the golf club striking the golf ball, respectively. The speed measuring mechanism measures the component of the speed of the golf ball which is parallel to the boresight. The correlator is electrically coupled to the speed measuring mechanism and correlates the measured component of the speed of the golf ball for each club with an empirically derived multiplier for use in determining the carry distance of the golf ball. The display is electrically coupled to the correlator and displays the carry distance of the golf ball so that the golfer can determine how far the golf ball which he has hit will carrying in flight.
