A golf training system generally includes a photoluminescent light-reactive surface and a light source that is placed on a golf club. During a training stroke performed over the photoluminescent surface, the light source excites phosphors in the light-reactive surface during a stroke and in doing so creates a transient visible record of the precise track the club head makes during the stroke. In some embodiments, the system can include a training ball having a phosphorescent material affixed to or integrated into the surface of the ball so that a light source placed on the golf club excites the phosphorescent material and indicates the point of contact between the golf club and the training ball.

A portable charger for an illuminated recreational flying object, such as flying discs (e.g., Frisbees), balls (i.e., golf balls, soccer balls, volley balls, etc.), badminton birdies, etc., is described. The portable charger permits a user to easily and rapidly charge the recreational flying object such as. The portable charger is scaled such that the illuminated flying disc is easily manually accessible from either side of the portable charger.

An angle-adjustable, movable sports practice, performance-enhancing, teaching device disclosed is a target that is dazzling, illuminating brightly colored for better optics which better assist in focusing and improving accuracy during practice. The device can be adjusted to different angles simulating various in-game scenarios, thereby providing a dynamic versatile training tool for athletes, applicable to a variety of sports where precision and accuracy are critical. The device comprises an image thereof, being brightly colored, having hooks or straps to attach to basketball goals, goal posts, or used in the practitioner's preferred sport. The devices hooks, hole or straps are for moving it to various positions, angles, and heights. The built in hole or hooks allow the device to be moved using a common twist off household broom or mop handle. The device is made of material that has energy absorbing properties which allow it to glow in the dark.

A cornhole game board lamp with infrared beam sensing and memory function is disclosed, including a table body, a battery box, a sensing control device, and a light strip. The table body has a tabletop with an entry hole for a cornhole bag to be threw. The sensing control device is located on the underside of the tabletop directly beneath the entry hole, and being ring-shaped. The sensing control device includes a sensing hole that is coaxial with and directly aligned with the entry hole. This arrangement resolves the issue of detecting whether a cornhole bag hit is successful in low-light environments and ensures that hits are accurately recorded in the current round. Each successful hit triggers a change in the light's color, allowing players to easily see how many hits they and their opponents have achieved through various sequences of light color changes.

A system for adjusting alignment of a golf club head includes a club shaft having a proximal end and an opposing distal end, with a hosel fitting fixedly secured to the distal end of the club shaft. A neck is rotationally coupled to the hosel fitting at a first end and a club head is coupled to the second end of the neck. The hosel fitting includes a reference line and the neck includes a series of angle index lines. The angle of the club face is adjusted by selectively aligning a singled angle index line with the reference line.

Disclosed herein is a sport practice device comprising a solid core ball having a bore formed therein, an elongated tether secured in the bore, a positioning washer configured to position the elongated tether inside the bore, and an adhesive configured to hold the elongated tether inside the bore. The elongated tether has a first end portion and an opposite second end portion, with the first end portion secured inside the bore and the second end portion configured to be attached to an anchoring mechanism. Corresponding systems and methods also are disclosed.
