Embodiments of mallet-style putter-type golf club heads comprising a first color and an alignment system to draw a golfer's eye towards a particular desirable location are described herein. The alignment system includes a central line extending rearward from a top edge centerpoint toward the rear portion and comprising a second color different from the first color. The alignment system further includes a focus element having a first grouping of lines and a second grouping of lines each extending rearward parallel to the central line and comprising a base abutting a top edge. Each of the first grouping of lines and the second grouping of lines further comprise at least the second color, a color saturation that changes as the lines extend rearward from the top edge, and line lengths that decrease as the first grouping of lines and the second grouping of lines are distributed further from the central line. The alignment system's changes in color, color saturation, and line length provide means to draw the human eye into focus at a particular desirable location to minimize mis-strokes that would cause undesirable variance from the desired trajectory or roll path.

Mallet-style putter head with alignment aid

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

Grooves of golf club heads and methods to manufacture grooves of golf club heads

A system includes a processor configured for leveraging reference ball flight data associated with an individual and a reference club having a reference loft angle to compute predicted ball flight characteristics for other candidate golf clubs having loft angles different from the reference loft angle. The predicted ball flight characteristics include predicted distances of golf shots the individual is expected to make using the candidate golf clubs that can further accommodate a computed recommendation of optimal loft angles for a consistently gapped golf club set.

Systems and methods for predicting ball flight data to create a consistently gapped golf club set

Embodiments of grooves of golf club heads and methods to manufacture grooves of golf club heads are generally described herein. Other embodiments may be described and claimed.

A golf club head including a face defining a loft plane, a rear, and a crown, the crown having a turbulator comprising a plurality of ridges. Each ridge includes a front surface having a first end nearest the face, a second end nearest the ridge apex, and a rear surface nearest the rear portion of the club head. The turbulator is positioned in a forward two-fifths portion of the crown in a front end to a rear end direction. The ridge apex of each ridge is positioned within the first 50% of the ridge length.

A system for computer-implemented golf shot analysis includes a tracking device and a computing device. The computing device accesses ball flight data generated by the tracking device in view of a predetermined gradient map and associated functionality to derive a performance metric that penalizes shots deemed to be offline.

Systems and methods for computing a strokes gained performance metric from ball flight data that considers predetermined offline information

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

Club head having balanced impact and swing performance characteristics

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Widths of the grooves vary in a direction extending between the heel end and the toe end.

A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located between the face and the apex, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators.

Golf club sensor housing

A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located at least partially between the leading edge and the apex, wherein the height of each turbulator decreases from the leading edge toward the rear portion.

Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.
