Abstract
A combination ball marker and stroke indicator device (10,20) has a first disc member (12,22) having a ground piercing pin (12b,22b) extending from a bottom face surface rotatably received through a pin receiving aperture (14a,24a) in a second disc member (14,24). Stroke indicating indicia (14b) are arranged on the top face surface of the second disc member and selectively alignable with a window (12a,22a) formed in the first disc member. A ground traction surface configuration (24e,24e′,24e″) is preferably formed on the bottom face surface of the second disc member. An annular recess (22d) may be formed in one of the disc members, for example, in the bottom face surface of the second disc member, to provide clearance between the indicia on the second disc member and the facing surface of the first disc member.
