The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and a tungsten weight member coupled to the toe and a tungsten heel weight member coupled in a hosel cavity.

A golf game assembly includes a plurality of goals. The plurality of goals may be arranged on a support surface. Each of the goals is comprised of a phosphorescent material to be visible at night. A plurality of golf clubs is provided. Each of the golf clubs is comprised of a phosphorescent material to be visible at night. A selected one of the golf clubs is selected by a player. A plurality of balls is provided. A selected one of the balls may be placed on the support surface. Thus, the player may strike the selected ball with the selected golf club. Each of the balls is comprised of a phosphorescent material to be visible at night.

Various embodiments of a golf club head comprising a body having a strike face, a heel portion, and a toe portion, a hosel having a body with a first end, extending from the heel portion of the body of the club head, and a second end, configured to receive a shaft, a cavity positioned adjacent to the body of the hosel, and an insert configured to be secured within the cavity are described herein.

A correlated set of golf club heads is provided. The set of golf clubs has a first club head that, when oriented in a reference position, includes: a first loft angle, a first heel portion, a first toe portion opposite the first heel portion, a first top portion, and a first sole portion that comprises a first sole rail having a first setback length. The set of golf clubs also has a second club head that, when oriented in the reference position, includes: a second loft angle greater than the first loft angle, a second heel portion, a second toe portion opposite the second heel portion, a second top portion, and a second sole portion that comprises a second sole rail having a second setback length that is different from the first setback length.

A sports wrist trainer comprising a first elongated swing member with grip attached to a second elongated swing member with head by means of a one way 90 degree hinge, and an elastic return means that returns and holds said swing members at a ninety degree angle one to the other. According to alternative embodiments, the wrist trainer is a bat used for learning batting swings or a golf club used for learning golf swings. The one way hinge rotates to provide a trainer having different swing configurations and to maintain the bat or club head facing the ball at impact just like at address. The elastic return means may be removed and the trainer used without it. A second one way 90 degree rotating hinge can be added to the first providing additional versatility and accommodating both right and left handed golfers.

A a method of making set of a plurality of at least a combination of three golf clubs of progressive lofts that are matched to provide identical swing characteristics; each of the golf clubs including a club head, a shaft and a grip at the upper end of said shaft; each club of the combination characterized by having an essentially identically located, computer designed center of gravity; each club being further defined by the shaft having an equal length, having an identical swing weight, identical grip weight and an identical club head weight.

Embodiments of a golf club set with progressive tapered face thickness coordinated with club loft are generally described herein. Other embodiments may be described and claimed.

A system for fitting golf clubs to golfers that enables an overall club length to be varied without varying a length of a shaft. The system enables a greater number of combinations of club characteristics, such as shaft flex, brand, and length, to be contained within a club fitting cart and/or for a same number of combinations of club characteristics to be contained within a smaller cart.

Some embodiments include a club head for adjusting vertical spin of a golf ball. Other embodiments of related systems and methods are also disclosed.

An electronics module in a gaming device includes an inertial measurement unit (“IMU”) for detecting acceleration motion, angular movements, and an optics assembly to optimally calculate a moment of impact and to predict a virtual trajectory of a virtual golf ball or other hypothetical object. The virtual trajectory of the target object may be displayed on a display screen either on the gaming device itself, on a computer, or on a television display. A haptics member, such as a vibration or sound element is positioned in the shaft housing and actuated to simulate a ball impact when the shaft housing is indicative of a swing.
