A method and an apparatus for playing golf on a hard surface comprises a replaceable striking pad attached to a conventional golf club head by means of at least one attachment means, a spiked ball, a portable ball trap to trap the spiked ball and an optional remotely controlled vehicle to position the portable ball trap. The replaceable striking pad includes a small lip at a bottom end on a front face and a holding ledge having substantially curved edges extending away from the bottom end of the front face. The holding ledge is adaptable to wrap around a bottom sole of the golf club head. The portable ball trap includes a thin flat platform with tapered edges, a central threaded pole positioned on the thin flat platform and a circular frame having a plurality of hinged tabs threaded to the central threaded pole.

A golf ball includes a land portion, and a plurality of dimples configured to be recessed from the land portion. Each of the plurality of dimples includes a circular bottom face, a circular opening configured to have a larger diameter than the bottom face, and a side face configured to connect the bottom face and the opening. The side face is configured to be linearly inclined so that the diameter of each of the plurality of dimples increases from the bottom face toward the opening. The diameter of the bottom face is 0.45 mm or more and 0.60 mm or less.

A high visibility reflective lacrosse ball and related methods of forming the high visibility reflective lacrosse ball. The high visibility reflective lacrosse ball includes a high visibility exterior that is clearly distinguishable from a background environment and is easily picked up by both camera lenses and human eyesight. The high visibility lacrosse ball can include a plurality of spaced apart, retroreflective markers that reflect a directional beam of light toward a light source. The high visibility exterior can include an exterior coating or layer having a color selected as being highly visible and/or fluorescent. The retroreflective markers can be formed from a reflective adhesive film. The exterior coating can be cured such that the exterior coating is robust and resilient and is neither degraded nor removed during typical game play.

A golf ball including a spherical body, first regions, and second regions. The spherical body includes a core layer and a cover layer made from a synthetic resin covering the core layer. Dimples are formed in a surface of the cover layer. First regions that are electrically conductive are formed on a surface of the spherical body. The first regions are formed on a spherical surface having a center of the spherical body as a center. The first regions are positioned at six vertices of an imaginary regular hexahedron such that the vertices are positioned on the surface of the spherical body and, thus, six of the first regions are formed. The second regions are formed in areas of the surface other than where the first regions are formed. The second regions have a radio wave reflectance lower than that of the first regions.

A golf ball including a core; an inner cover layer formed from a thermoplastic composition and having a thickness of about 0.005 inches to 0.40 inches and a surface hardness of about 60 Shore D or greater; and an outer cover layer formed from a thermoset material and having a thickness of about 0.01 inches to 0.05 inches and a surface hardness of about 60 Shore D or less. The thermoplastic composition has a first melt flow index at 280 C. under a 10-kg load of less than about 35 g/10 min and a second melt flow index at 265 C. under a 5-kg load of less than about 10 g/10 min.
