摘要： A golf round timing device is provided for determining the time at which a golfer is to start a golf hole. The golf round timing device comprises a base and a circular disk member. The base has an outer arcuate row of indicia, indicative of time intervals, disposed thereon. The circular disk member has a smaller radius than the outer arcuate row and is rotatably mounted at a mounting point on the base in such a fashion as to be concentric with the outer arcuate row of indicia. The circular disk member has at least one inner arcuate row of indicia indicative of holes on a golf course so that when the inner arcuate row of indicia is aligned with the outer arcuate row of indicia, the time at which the golfer is to start a golf hole may be determined.

摘要： An aerodynamic golf club head is provided for increasing the speed of the head during a swing. The head comprises a head body having a face side for hitting the golf ball, a back side at an opposite side of the face side, a toe side connecting the face side to the back side, a heel side at an opposite side of the toe side, and an outer surface extending substantially between the face side and back side and formed by a sole side and a top surface. A substantially straight through hole formed in the head body is provided for allowing air to pass therethrough. The through hole has a first opening which opens in the sole side adjacent the striking face side and a second opening which opens in the top surface adjacent the back side.
