ABSTRACT:
A golfing apparatus for determining the carry distance of a golf ball in flight includes a doppler radar unit, a measuring cone, a correlating circuit and a display. The doppler radar unit has a housing, a transmitter and receiver unit and a counter. The transmitter and receiver unit is disposed in the housing and transmits electromagnetic energy towards the golf ball in order to produce a plurality of pulses which is the Doppler shift of the electromagnetic energy. The counter is electrically coupled to the transmitter and receiver unit and counts the plurality of pulses over a preselected period of time. The golf ball passes through the measuring cone and the doppler radar unit measures speed of the golf ball therein. The correlating circuit is electrically coupled to the doppler radar unit and correlates the measured speed of the golf ball with a carry distance. The display is electrically coupled to the correlating circuit and displays the carry distance so that the golfer can determine how far the golf ball which he has hit will carry. The correlating circuit includes a selecting mechanism which selects the preselected period of time so that the counter counts out directly the number of yards which the struck golf ball will carry.
