The invention concerns a method for determining the length of the shaft of an individually adapted golf club. In accordance with the invention the lengths (11 to 15) of body parts of a golf player, which are decisive for the height position of his hands above the floor in the address position and during the swing, are measured and the length of the shaft is calculated from the measured lengths and predetermined angles (A, B, C, D) between the body parts as well as a pre-determined angle (E) betw...

The invention related to methods and a system fro precisely fitting a golfer to a selected stiffness of golf shaft and to a selected flex choice of golf shaft. Heretofore and presently, a long felt need exists for methods and means to precisely fitting a golfer to a particular golf shaft whose values of stiffness and flex choice are applicable to a player of a specific skill level in the game of golf. Present day club fitting systems and methods are very expensive, complex and do not provide met...

A golf ball mark repair tool having the advantage of promoting the proper technique for repairing a ball mark on a green is provided. The ball mark repair tool generally includes a body member and a plurality of prongs extending from the body member. The prongs have an arcuate shape and project forwardly from the body member to facilitate pushing the edge of the ball mark towards the center. A method of using the ball mark repair tool is also provided.

Improved golf club heads indicating the location of an optimum hit point on the striking face for maximum shot distance of any hit location on the face ("maximum distance spot", called MD) and an indication of a second optimum hit point giving best distance, with the condition of minimum or no change of torque caused feel as perceived by the golfer at impact ("best feel spot," called BF) are disclosed. Methods to locate these optimum locations are described. It has been widely assumed and believ...

A method of playing a golf game on a golf course which includes approach greens on a forward fairway, consecutively numbered teeing positions which are further identified as being the tee positions for holes having specified pars, a rearward putting area including a plurality of holes therein numbered to correspond with the consecutively numbered teeing positions, and conventional hazards forward and rearward of the teeing positions. The method of play involves the steps of hitting one ball forw...

A computer implemented method for fitting golf clubs for golfers to accommodate the swing behavior of an individual's golf swing using combinatorial logic at both the global and local levels. Specifications for a full set of golf clubs are derived from the intersection of two models labeled FITMODEL and SPECPRO. Input data is first gathered (204) and normalized (206) based upon chosen parameters. The chosen parameter relationships are analyzed (208) by FITMODEL, which in turn prescribes specific...

The golf club head (20) of the present invention allows for the face angle, lie angle, loft angle and shaft diameter of the golf club to be customized to a golfer. The golf club head (20) of the present invention is able to accomplish this by providing a major body (22) and a minor body (23) having a crown section (24) and hosel section (25). The minor bodies (23) have different hosel section (25) orientations thereby allowing for different face angles, loft angle, lie angles and shaft diameters...

Disclosed is "Golfball.RTM.", a system and method of playing a team golf game in which teams consisting of nine players each compete in a match play format with the object being to win the greater number of holes, including rules for player substitutions, line up disclosure, simultaneous play, extra holes in case of ties, real time communication of the game score and the number of holes remaining to be played to all participating players and the display of the current status of the game and all ...

Golf training system and method for improving ones skills in putting a golf ball including providing a golf putter having a putter face, placing said putter face in right angle alignment to a golf ball disposed on a putting surface, aligning the hands, shoulders and head generally at right angles to the line of intended movement of the golf ball, positioning a spinner member having an inclined ramp-like surface adjacent the rear of the ball and generally at right angles to the intended line of m...
