Total Claims: 14
Claim 1
Independent Claim
99 words
In a golf swing plane sensor, the combination comprising (a) golf club having a shaft and ball striking head, and (b) means associated with the club to project a first light beam in a first direction lengthwise of the shaft to intersect the ground as the club is held in ball addressing position and then swung rearwardly, and to project a second light beam in a second and diametrically opposite direction lengthwise of the shaft to intersect the ground as the club is swung backwardly and upwardly so the free end of the shaft is directed toward the ground.
Claim 2
Dependent Claim
