A golf club includes a club head having two body members and a hosel. Each of the two body members has a planar striking face, and the two faces determine an angle of 90.degree.. Each of the two body members also has a bath surface which is grooved to reduce weight. The hosel joins the body members near the vertex of the 90.degree. angle. A club shaft is inserted into the hosel. Indicia are formed on the upper surfaces of each of the body members which are parallel to a bisector of the 90.degree. degree cycle to aid in aligning the club with the golf ball and the cup into which the ball is to be putted. Tuned resonators are mounted on each of the body members opposite the point on each striking face where the striking faces are tangent to a golf ball touching both faces. The resonators produce audible sounds, which are a function of how the club head strikes a golf ball.

This application is a continuation-in-part of application Ser. No. 06/091,176, filed Nov. 5, 1979, now U.S. Pat. No. 4,290,606 entitled Nonpredictable Game Projectile, by Thomas J. Maxwell, the inventor of this application.
A golf putter for improving the accuracy of putting is provided for putting a golf ball along a desired line of travel. The putter has a shaft, and a sleeve fixedly connected to the shaft, and a plate fixedly connected to the sleeve. The plate has an upper surface, a lower surface, a rear surface and a front surface. The front surface has a pair of vertical contact surfaces in the shape of a V-shaped groove. The vertical contact surfaces are disposed at equal angles of 30 degrees with a plane that passes through the center of gravity of the plate.
A golf putter includes a sighting line formed by the intersection of two faces, a narrow bottom surface and a striking face having a cut out portion therein. The intersection of the two faces improves sighting for putting stroke with the narrow bottom and striking face cutout permitting putting in heavy grass conditions. The putter also has a curved bottom which permits making both a hit-down stroke and a lofting stroke and means for adjusting the overall weight thereof.
An electronic athletic instrument which measures the differences in time in which shock waves (or vibrations), caused by a movable game element hitting the instrument, are detected by different sensors, located on the periphery of the surface. By means of predetermined open window time periods and possible delays, as well as effecting different dimensional zones, this instrument is able to provide for instructive feedbacks to different players with different skill levels.
An L-shaped putter has a head 2 fixed to a tip end of a shaft 1, wherein the head 2 is formed in a planar L-letter shape including a face part 3 and a long sidewall 4 extending rearwardly from a heel-side end of the face part 3. A toe-side end of the face part 3 and an end of the sidewall 4 are each provided with a weight 6, thereby forming an oblique center-of-gravity line connecting the two weights. Thus, the center of gravity of a sweet spot can be set at a deep position toward the rear of the face, and the generation of twisting forces in the face part 3 at the time of putting is prevented to give a self diagonal retaining inertia, whereby a ball can be rolled accurately along the target line.
A golf putter has a head (1) with a planar striking face (5). The putter head has aiming assisting elements (3, 3', 4 4') which comprise at least two portions (4, 4') each extending rearwardly with respect to the striking face of the putter head such that when seen from above and in a rearward direction, said two portions (4, 4') diverge outwardly. In order to assist increased accuracy when aiming, the two portions are arranged at such an angle to the striking face that the virtual extension (CG, DG) of each portion in a direction forward of the striking face (5) is substantially tangential to a standard golf ball placed at the striking face.
