An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

Golf ball

A golf ball with an aerodynamic design is disclosed herein. The aerodynamic design has a protrusion at a center of a hex geometry representing an increase in ball radius greater than 0.0005 inches from a minimum ball radius. The minimum ball radius is located between 0.01 and 0.04 inch (11%-46%) from the center of the hex geometry.

A unique method of embedding an RFID chip into the core of a golf ball and using it in the application of a limited flight range ball for use in a range setup that can receive and monitor RFID signals is disclosed herein. The density of the core material is adjusted in relation to the mass of the RFID chip. The golf ball with an embedded RFID chip conforms to a mass limitation of the USGA.
