Abstract: A putter-type golf club head that, when oriented in a reference position, includes a rear portion in communication with, and rearward of, a blade portion and having a rear portion top surface. The club head also includes a projection extending upwardly from the rear portion top surface, the projection having a projection top surface, a heel-ward side surface, a toe-ward side surface, and a rear surface, the projection top surface comprising a generally planar surface. And the club head further includes a sightline formed in the projection top surface and that comprises a groove at least partially filled with a filler material having a visually contrasting appearance to portions of the top surface surrounding the groove, the groove defining a virtual center line segment oriented in a substantially front-to-rear direction at a substantially constant height from a lowermost point of the sole between 16 mm and 26 mm.

Abstract: A golf club head is composed of a head main body comprising a face portion, a crown portion and a sole portion, and having a hollow, and a weight member disposed in the hollow of the head main body. The weight member is fixed to a toe side of the head main body at a toe side end portion and fixed to a heel side of the head main body at a heel side end portion so as not to contact with the inner surface of the head main body between the toe side end portion and heel side end portion. The cross-sectional area of the weight member is decreased in a central portion in the toe-heel direction than its heel side and toe side.

Abstract: A shaft 6 includes a plurality of layers formed by fiber reinforced resins. The layers include a hoop layer and bias layers. The hoop layer includes a full length hoop layer s9 constituted with a prepreg having a fiber elastic modulus of equal to or greater than 30 (tf/mm2) and having a fiber weight per unit area of equal to or greater than 50 (g/m2) but equal to or less than 80 (g/m2). The bias layers s2, s3, s4, and s5 include high elasticity containing bias layers s4 and s5 constituted with a prepreg contacting a high elastic pitch-based carbon fiber having a fiber elastic modulus of equal to or greater than 80 (tf/mm2). Preferably, the full length hoop layer s9 is disposed outside the high elasticity containing bias layers s4 and s5.

Abstract: A golf club 2 includes a shaft 6 having a weight of 50 g or less. The shaft 6 has a ratio of a center of gravity of 0.54 or greater. Respective EI values measured at intervals of 100 mm from a point 130 mm distant from a tip end Tp are defined as E1 to E10. A first region, a second region, and a third region are defined by boundaries at respective points having distances of 230 mm and 830 mm from the tip end Tp. In a graph on which the EI values are plotted, gradients of approximate straight lines in the first region, the second region, and the third region are defined as M1, M2, and M3, respectively. M1 to M3, E9/E6, and E10/E6 are fall within respective specified scopes. M3 is greater than M2.

Abstract: A method of customizing a golf club, wherein the method includes generating operating data representative of a user operating a mechanical device. The operating data is generated by a first sensor sized and configured to be removably positioned in a mounting port formed on the mechanical device during operation of the mechanical device. The sensor is interchangeably positionable in the mounting port with at least one mass insert, the at least one mass insert being adapted to be interchangeably positioned in the mounting to provide at least two different mass configurations. The method further includes determining a recommended configuration of the at least one mass insert specific to the user based on the operating data generated by the sensor, and transmitting information representative of the recommended mass insert.

Abstract: A sporting apparatus includes a monitoring device. The monitoring device may add no weight to the sporting apparatus relative to a comparable sporting apparatus without the monitoring device. The monitoring device may have a center of gravity substantially aligning with the center of gravity of the sporting apparatus, resulting in a sporting apparatus with a monitor having substantially the same center of gravity as a comparable sporting apparatus without a monitor. The sporting apparatus monitor may be configured to trim unreliable post impact swing data and replace it with extrapolated pre-impact swing data and/or more reliable post impact swing data.
