ABSTRACT:
A sight level indicator for golf clubs connectable into a mating slot or groove formed into the golf club handle adjacent its upper end. The invention includes a liquid-filled, transparent vial having an elongated, preferably cylindrical body, the liquid forming a viewable gas bubble within the vial as indicium of true horizontal orientation of the vial. The slot or groove is formed transversely into the handle and perpendicular to the longtitudinal axis of the golf club such that, when the gas filled bubble within the vial indicates a true horizontal orientation of the vial, the golf club is visually perpendicular to the ground. The various embodiments provide for minimizing the felt discontinuity in the handly surface grasping area while still insuring quick and accurate viewability of the invention in use. The invention may also be provided as a completed golf club assembly.
