A left handed golfer follows the same steps with the left and right hand instructions reversed.

In Figure 5a the golfer places the head of a golf club having the grip of the present invention on the ground. The face of the club is aimed towards the target area for a golf ball. In this orientation the indicia on the grip will be facing upward and away from the golfer.

In Figure 5b the golfer places the first marking of the glove (the 'thumb pad') onto the first indicia of the grip (the 'thumb pad reference').

Then, as illustrated in Figure 5c, the golfer closes his/her fingers about the grip. Figure 5d shows that the left hand of the golfer is now correctly position on the golf club. The line formed between the thumb and the forefinger on the left hand points towards the right shoulder.

Figure 5e illustrates how a second mark on the glove (the 'palm line') and second indicium on the grip (the 'line reference') can be used to check if hand positioning is correct. The golfer opens their left hand to check if the palm line and line reference are aligned. The palm line may include a broad corridor and a narrow line. The broad corridor should align with the width of the grip and assists checking alignment while minimizing the extent to which the golfer must open their left hand. This reduces the risk of the club grip moving relative to the glove and spoiling alignment. The narrow line indicates precise alignment of the glove and grip, but requires the user to roll their hand open to check correct contact alignment.

In Figure 5f the right hand is placed on the grip so the grip runs across the base of the fingers with a small gap to the forefinger.

The golfer then wraps their right hand on top of their left hand and aligns their right forefinger and right thumb with a third indicium on the grip as illustrated by Figure 5g.

The golfer's right thumb pad sits atop the left thumb and the line formed between the right forefinger and right thumb is parallel to the line formed between the left thumb and left forefinger.

The golf club grips can have a range of different external diameters and can include indicia of vaiying geometry and size matched to the hand size of a golfer. A complimentary range of sized golf gloves with markings of varying geometry and size matched to a suitable grip may also be provided.

In use a golfer will select a suitable glove(s) matched to their hand size from the range of gloves. A grip or a club with a grip is selected that matches the glove and the hand size of the golfer such that in use the markings on the glove and grip will align when the golfer's hand(s) are correctly positioned about the grip.

The golf glove may be made from leather, knotted acrylic material, cotton, wool, transversely isotropic material or any other suitable material. The glove markings may be printed on the glove, or stained or otherwise made noticeable on the background glove material.

Where in the foregoing description reference has been made to elements or integers having known equivalents, then such equivalents are included as if they were individually set forth.

The foregoing describes die invention and a preferred form(s) thereof. Alterations and modifications as will be obvious to those skilled in the art are intended to be incorporated widiin the scope hereof. For example: the golf club grip can be configured for direct registration with the thumb pad of the golfer without a glove. ■ i--J Office of NX 2 7 OCT 2006
