Golf ball marker systems for marking the position of a golf ball

Abstract

A golf ball marking system includes a first marker disc with a ground-anchoring spike and a larger second marker disc with a marker receptacle. The marker receptacle receives the first marker disc and allows the second marker disc to rotate around the first marker disc along a vertical axis passing through the center of the first marker disc. The marker receptacle includes a channel with an opening configured to receive the first marker disc when the discs are aligned in an engagement orientation. Once engaged, the first marker disc is retained within the receptacle as the second marker disc rotates. A shelf along the bottom surface of the second marker disc forms a channel bottom that guides and retains the first marker disc during rotation. Magnetic components may be included in either or both discs to enhance retention. The system includes alignment indicators to assist with putting alignment.
