A green simulation apparatus may comprise a covering forming a configurable upper surface with a changeable contour and being flexible such that the covering is movable between a base condition in which the upper surface has a substantially planar configuration and a contoured condition in which the upper surface has a contoured configuration. The apparatus may also comprise a covering support assembly configured to support the covering in the base condition and the contoured condition.

An exerciser includes: sensor installation units provided to be spaced apart from and face each other in a direction parallel; a radiation unit for radiating light, in a first sensor installation unit; a light receiving unit for receiving the light radiated from the radiation unit, in a second sensor installation unit; a speed detection unit for detecting a speed of the golf ball by checking a moment the golf ball passes; a position measurement unit for measuring a position of the golf ball; an operation control unit for performing calculation to detect an initial position value of the golf ball and a moving speed Vb and a moving distance Hb of the golf ball; and a storage unit for storing the measured speed Vb and distance Hb of the golf ball.

A multi-layer underlayment pad for use beneath activity surfaces such as artificial putting greens, such pad including a first foam layer comprising expanded polyethylene having a thickness ranging from about 0.25 inches to about 2 inches; and a second foam layer comprising polyurethane having a thickness ranging from about 0.125 inches to about 1 inch.

Proposed is an apparatus for checking a golf divot, which checks a position where a golf club comes into contact with the ground, a ground contact area, or a trace of the golf club when a user hits a golf ball with a golf club, so as to enable improvement of the user's swing, the apparatus including: a ball resting plate body having multiple pin-holes formed therethrough; multiple pins which are inserted into the pin-holes of the ball resting plate body, respectively, to vertically move and installed to allow upper end portions thereof to protrude upward from the ball resting plate body; and a ball resting plate body support means which supports the ball resting plate body in a state where the ball resting plate body is spaced a predetermined height apart from the ground.

A golf ball address training method including steps of providing a club set and a ground mat having a lateral line, selecting a highest loft club, orienting the lateral line up-range, and aligning an up-range foot with the lateral line, alternatively selecting a lowest loft club, orienting the lateral line down-range, and aligning a down-range foot with the lateral line, alternatively selecting a lowest high loft club, orienting the lateral line up-range, and placing the up-range foot a greatest distance up-range, alternatively selecting a highest low loft club, orienting the lateral line down-range, and placing the down-range foot a greatest distance down-range, alternatively selecting low or high loft intermediate clubs, correspondingly orienting the lateral line down-range or up-range, and correspondingly intermediately placing the down-range and up-range feet.

A sports training apparatus includes a flat mat having visible indicia adapted to indicate placement of at least one foot of a user of the apparatus, and a foot restraint adapted to hold a front foot of the user so that the front foot remains in contact with a top surface of the flat mat. The front foot is in an intended direction of a swing of a sports implement.

The present invention is to provide a divided driving swing platform including a plurality of plates divided from the swing platform on which a user can perform a golf swing with a golf club and operated stably by increasing a degree of freedom of movement of each of the divided plates so that each of the divided plates can move in various ways and interference between the divided plates does not occur when each of the divided plates is driven and operated.

A golf mat has a down-blow impact mat removably placed in a cutout formed in a base. The upper surface of the down-blow impact mat has a hitting section that slopes down gradually from the high point to a target point. The down-blow impact mat also has a lower portion having a sloping section and a flat section. The golf mat disclosed helps to improve the golfer's takeaway swing and the downswing so the golfer may practice his or her swing, including but not limited to, better mastering the elusive two-plane golf swing, with the guidance of the sloped hitting surface.

Disclosed herein is an apparatus for facilitating simulating golf play on golf courses. Further, the apparatus comprises a golf mat, a golf ball, an external sensor, a processing device, a storage device, and a communication device. Further, an internal sensor diposed in the golf ball generates internal sensor data based on detecting a striking parameter of a striking of the golf ball. Further, the external sensor generates external sensor data based on detecting a motion parameter of a motion of the golf ball. Further, the processing device analyzes the internal sensor data and the external sensor data, generates a path parameter of a path of the golf ball, and generates a representation of the golf ball and the path in an environment representation of a golf course based on the path parameter and golf course data. Further, the storage device retrieves the golf course data.

A method for selecting a most suitable golf club from a set, where the shafts of the set are of different levels of flexibility along the shaft, includes using a pressure sensing mat upon which the player places both feet while carrying out a sample swing to measure forces applied by feet of the player during the stroke. The pressure sensing mat provides output signals indicative of vertical forces, lateral forces, both heel to toe and side to side, lateral speed, both heel to toe and side to side applied by the feet of the player during the swing and a processor operating on the signals selects certain ones of the output signals to calculate a load factor from the selected signals which is used to select one of the set most suitable for use by the player using a color coding system applied to the load factor.
