A hand-held device for marking a golf ball has a handle and first and second
forks
(or arms) for holding the golf ball between the forks. The golf ball is held between
a ball-receiving portion of the first fork and a rubber gripper rotationally mounted
to the second fork which can be manually turned to rotate the ball between the
forks. A spring-loaded marker presses its tip against the ball to inscribe a line
as the ball rotates against the tip of the marker. In operation, the device can
circumscribe a continuous line around the circumference of the ball without resetting
the ball, as well as any arc less than 360 degrees. By resetting the ball perpendicularly
after a first arc is inscribed, a second, intersecting arc can be inscribed to
define a cross in two easy steps.
