Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a front portion, a back portion, a toe portion, a heel portion, a sole portion, and a top portion. A face portion is attached to the front portion to enclose the interior cavity. The golf club head may further include a port on the body portion that is connected to the interior cavity. A first mass portion may be coupled to the body portion such that the port is configured to receive the first mass portion to close the port. A second mass portion may be coupled to the body portion and include a different material than a material of the first mass portion. The maximum width of the interior cavity may be below a horizontal midplane of the body portion and above the port. The interior cavity may be at least partially filled with a filler material from the port. The interior cavity may at least partially extend over the port at a location of the maximum width. Other examples and embodiments may be described and claimed.

There is provided a portable wall-mountable sports stick rack. The rack has a compliant support having a front side and an opposed rear side; a plurality of sports stick retaining channels along the front side adapted to receive a sports stick therethrough; and an adhesive layer associated with the rear side, the adhesive layer configured to removeably mount the sports stick rack to a wall surface.

Starting platform assemblies may be provided with swimming pools for competitive and/or recreational purposes. A starting platform assembly may include a frame supporting a starting platform. Starting platform assemblies may include various combinations of optional features such as but not limited to informational panels and displays, storage areas, side handles, backstroke bars, movable mounting steps, and/or wedge anchors.

An apparatus for a bag toss game and method of play are disclosed. An offensive game board and a defensive game board each include at least one support member position on a first side of the game board. The at least one support member angles a top surface of the game board above a ground surface. A plurality of cutouts are positioned through the top surface of the game board, each of the plurality of cutouts to receive a bag tossed through one of the plurality of cutouts, wherein each of the plurality of cutouts is associated with a consequence.

An elongated putting strap contained in a rolled configuration within a housing. When used, the elongated strap is unrolled and laid out on a putting green. The putting strap may include short, medium and long putting zones and corresponding short, medium and long target zones. The putting zones may include hash marks designating distances to corresponding target zones. Use of the putting strap provides golfers with an opportunity to putt from various distances in an attempt to bring the golf ball to rest in the proper target zone corresponding to the putting zone from where the golf ball was struck. The target zones may be nested within one another.

A golfing aid includes a connector portion, a first leg and a second leg. Each leg has a first end connected to the connector portion and at least one of the first and the second leg being pivotable about the connector portion. The connector portion includes predetermined positions for arranging the first leg and the second leg. The predetermined positions include a first pivot position, a second pivot position and a third pivot position.

A golf ball includes an assist mark 10 and a guide mark. The assist mark is straight in plan. The guide mark is distorted in plan. The guide mark is in the shape of an arrow as a whole. The guide mark looks straight to a player swinging a golf club. The player moves the head of the golf club along the direction of the guide mark.

A golf swing analyzer system for analyzing a golfer's golf swing. An inertial measurement unit (IMU) may be used to capture data regarding the swing. The IMU may be oriented along a hosel-axis and a face-axis to reduce the complexity of calculations to determine the path of the swing. Two IMUs may be used to permit correction of captured data, different orientations of the IMUs to increase accuracy of captured data, and a doubling of the captured data. The IMU may include a magnetometer that cooperates with a magnet that is adapted to indicate the time at or near impact of the head of the golf club with the golf ball. An LED system provides visual information to a user regarding the swing while the swing is being made.

A method for manufacturing an artificial climbing structure comprises: a) providing a framework, suitable for supporting the artificial climbing structure; b) mounting at least one structural panel on the framework; c) providing at least one covering panel, comprising patterns; d) mounting the covering panel on the structural panel in a removable manner; e) mounting at least one climbing hold on the covering panel; and f) fixing the climbing hold to the structural panel, through the covering panel, and in a removable manner.

An apparatus is provided for indicating a golf stance. The apparatus includes foot markers configured to provide an indication of where on the ground the golfer should place his feet and a reference grid arranged on the ground in a predetermined relationship relative to the foot markers, the reference grid including a plurality of points arranged in labelled rows and columns, thereby to identify each point in the reference grid. The apparatus has a golf club attachment including an attachment formation for attachment to a shaft of a golf club and an aiming aperture or reticule, wherein the golfer is able to align his eye with one of the points on the reference grid using or through the aiming aperture. The apparatus further has a ball marker and a support stand which supports the ball marker at an elevated position above the ground where the ball is intended to be placed, wherein the golfer is able to align his eye with the ball when placed on the ground using the ball marker. In use, (1) placement of the golfer's feet, (2) alignment of the golfer's eye (and accordingly head) with one of the points on the grid and the golf club using the aiming aperture, and (3) aligning the golfer's eye (and accordingly head) with the ball using the ball marker causes a desired or predictable stance of the golfer.
