1. A golf ball having a plurality of radar detectable marks disposed on an intermediate layer thereof, wherein, when all of the radar detectable marks are radially projected onto the outer surface of the ball to form an overall pattern of projected radar detectable marks,
the overall pattern of projected radar detectable marks consists of:
a first series of three or more marks where each mark in the first series has a geometric center located on a first 1.5 mm wide great circle band on the outer surface of the ball, and
a second series of three or more marks where each mark in the second series has a geometric center located on a second 1.5 mm wide great circle band on the outer surface of the ball, and
wherein the portions of the first and second great circle bands on which the first and second series of three or more marks are located each have a length of at least 40% of a circumference of the ball and no more than half of the circumference of the ball,
wherein each of the marks of the first and second series of marks have:
a length of 10 mm or less, and
a width of 2 mm or less, and
wherein a separation distance defined between each pair of adjacent marks in the first and second series is 0.5 mm or greater, and
wherein the first and second series of three or more marks each comprise no greater than five marks,
wherein the first and second series of three or more marks each have an angular length of about 166°,
wherein the first series of three or more marks are bisected by a first plane, the second series of three or more marks are bisected by a second plane, and the first and second planes are separated by an angle of about 90°.
