Golf ball marker

1. A ball marker, comprising:

a body having a generally geometric perimeter shape and a top surface;

an arcuate ball location reference adjacent the top surface;

at least one elongate alignment indicium disposed on the top surface and generally perpendicular to the arcuate ball location reference; and

additional linear alignment indicia disposed on the top surface, wherein the additional alignment indicia are identical and rotated relative to the next adjacent indicium by a constant angle about a focal point spaced from the ball location reference, wherein the ball location reference is interposed between the indicia and the focal point, and wherein the additional linear alignment indicia are symmetric about the elongate alignment indicium in both shape and location.

2. The ball marker of claim 1 , wherein the body includes at least one concave arcuate surface intersecting the top surface and the arcuate ball location reference is an arcuate edge formed by the intersection of the top surface and the at least one concave arcuate surface.

3. The ball marker of claim 2 , wherein the concave arcuate surface has a radius of curvature in the range of 0.725 inch to 0.975 inch.

4. The ball marker of claim 1 , wherein each of the additional alignment indicia is generally perpendicular to the arcuate ball location reference.

5. The ball marker of claim 4 , wherein the alignment indicia include at least three indicia.

6. The ball marker of claim 1 , wherein the geometric perimeter shape is one of a square, a rectangle and a triangle.

7. The ball marker of claim 1 , wherein the geometric perimeter shape is curved.

8. The ball marker of claim 1 , further comprising a focused light source coupled to the body.

9. The ball marker of claim 1 , further comprising a divot tool coupled to the body.

10. The ball marker of claim 1 , wherein the additional linear alignment indicia consist of linear segments and each segment is perpendicular to the arcuate ball location reference.
