A golf apparatus and method for marking the position of a golf ball and supporting a golf club serves to mark the position of golf balls when visibility is restricted, and supporting golf clubs in a vertical orientation, easily accessible for play. The golf apparatus provides a stem defined by a flag end and an anchor end. One or more flag members detachably attach to the flag end. The flag members are defined by a linear upper edge, a curved lower edge configured to retain golf clubs, and defined by colors and patterns for identifying individual player golf balls. The anchor end of stem couples to an anchor housing that forms channels to receive golf clubs and cigars. The anchor housing contains an interior weight member that creates a center of mass, which maintains the stem upright. The upright position enhances visibility of flag members.

According to the present invention, provided is a system for providing golf information, the system including: a green photographing unit for photographing an image of an area including a green on a golf course and communicatively connected to a communication network to transmit green image data to an outside; a golfer terminal that is carried by a golfer on the golf course and communicatively connected to a communication network to transmit golfer position data to the outside; and an information providing server that is communicatively connected to the communication network to generate golf information using the green image data and the golfer position data and transmit the generated golf information to the golfer terminal.

A golf club head includes a striking face including a face center, a top portion, a sole including a leading edge and a trailing edge, and a rear side opposite the striking face. The rear side includes a channel configured to permit bending at least a portion of the sole to cause plastic deformation to change a bounce angle defined as an angle between a virtual sole line and a virtual ground plane when the golf club head is orientated in a reference position where the golf club head is addressed to hit a golf ball.

A golf club shaft includes a shaft body having a butt end and a tip end, and a counterweight member on an outer periphery of the shaft body between the butt and tip ends. The counterweight member is made of a fiber composite material configured in a way that the counterweight member has a color visually distinguishable from that of the shaft body.

Examples of golf equipment covers and methods to manufacture golf equipment covers are generally described herein. In one example, a golf club head cover may include a body portion having an opening to receive a golf club head. The golf club head cover may include a magnetic portion that allows the golf club head cover to be magnetically attached to a metallic structure, such as a steel golf cart basket. The golf club head cover may include a magnet identifier located on or near the magnetic portion. The magnet identifier may notify an individual as to a location of the magnetic portion to aid the individual when the attaching the magnetic portion to the metallic structure. The golf club head cover may include a golf club head identifier that remains visible when the magnetic portion is magnetically attached to the metallic structure. Other examples may be described and claimed.

Disclosed herein is a driver-type golf club head that is made from at least one first material, having a density between 0.9 g/cc and 3.5 g/cc, at least one second material, having a density between 3.6 g/cc and 5.5 g/cc, and at least one third material, having a density between 5.6 g/cc and 20.0 g/cc. The first material has a first mass no more than 55% and no less than 25% of the total mass of the golf club head. The second material has a second mass no more than 65% and no less than 20% of the total mass of the golf club head. The third material has a third mass equal to the total mass of the golf club head less the first mass of the first material and the second mass of the second material.

A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.

A shaft for a golf club includes a first end, a second end, and a demarcation. The first end is adapted to attach to a club head. The second end is adapted to receive a grip distal to the first end. The demarcation is positioned at or adjacent to the balance point of the golf club between the first end and the second end.

A ball-washing device is described herein. The device includes a housing having a top wall, a bottom wall and a peripheral wall extending between the top wall and the bottom wall to define a cavity of the housing. The top wall has an opening shaped to receive a ball into the cavity and a pair of guides positioned on an inner surface of the opening. The peripheral wall has at least one brush positioned on an inner surface of the peripheral wall to engage the ball when the ball is in the cavity. The device also includes a plunger configured to slidingly engage the housing. The plunger has a body portion configured to slidingly engage the guides as the plunger is inserted into and removed from the cavity through the opening. The body portion is also configured to retain the ball as plunger is inserted into and removed from the cavity through the opening. The plunger also has a cap coupled to the body portion and configured to rotate relative to the body portion to secure the plunger to the housing when the body portion is in the cavity.

A portable golf ball scrubber assembly includes housing that has an entry extending into an interior of the housing for receiving a golf ball and a cleaning solution. A plurality of straps is each coupled to the housing and each of the straps is extendable around a pole on the golf cart for suspending the housing therefrom. A first track is positioned within the housing and a second track is positioned within the housing. The second track is positioned in the housing and the second track surrounds the first track. The second track has an opening to receive the golf ball. A plurality of bristles is each of the bristles is positioned within the housing to scrub the golf ball. A crank is rotatably coupled to the housing and an arm is positioned the housing which engages the crank. The arm travelling around the first track and the second track when the cranks is rotated to scrub the golf balls on the bristles.
