Abstract: A method for manufacturing a golf ball. The method includes creating a core with a cavity therein and positioning electronics in the cavity. The method further includes filing the cavity with a fill material while the electronics are positioned in the cavity such that the core, the electronics, and the fill material together form a spherical body, and such that when the fill material is cured the spherical body is balanced about a center thereof. The method further includes curing the fill material and covering the spherical body with an exterior cover.
