Golf balls having at least one radar detectable mark

A golf ball comprised of a core, an intermediate layer, and a cover, the golf ball further having a plurality of radar detectable marks disposed among two or more layers thereof, wherein the plurality of radar detectable marks are comprised of an electrically conductive ink, and includes at least eleven non-circular-shaped marks,

• wherein, when all of the radar detectable marks present on any layer of the ball are radially projected onto the outer surface of the ball, the radar detectable marks are spaced such that the centroid of each of the radar detectable marks is positioned at a vertex of one of a plurality of spherical triangles created from a plurality of great circle arcs, wherein:
• 2V−4=T
• 3T/2=E
• T−E+V=2
• where E is the total number of great circle arcs, T is the total number of spherical triangles, and V is the total number of vertices;
• wherein the plurality of radar detectable marks include at least one first mark having a first shape and at least one second mark having a second shape,
• wherein the first shape of the radar detectable marks is a stripe, and the second shape of the radar detectable marks is a chevron, and
• wherein the layer on which the plurality of radar detectable marks are disposed on is at least one of:
• an outer surface of the core,
• an inner or outer surface of the intermediate layer, or
• an inner surface of the cover.
