with the protrusion 2 d and the projections 2 e to control the linear position of the screw 3 within the case 2 in the preferred embodiment of the present invention the helical groove 3 c with one and one inch of linear travel per rotation of the screw 3 within the case 2 works well for ten settings corresponding to ten common golf club variations running from a wedge through number 1 2 and 3 woods through numbers 4 through 9 irons in operation after a golfer has selected his club the golfer rotates the screw 3 within the case 4 until the club number indicated by the tee height indicator 3 h matches the case reference 2 f of the case 2 referring to fig4 the device 1 is inserted over a golf tee 5 so that the convex surface 3 g of the screw 3 mates with the golf tee 5 the golf tee 5 is inserted into the ground 100 shown in fig7 until the case 2 touches the ground the golf tee 5 is now set at a height with respect to the ground 100 in accordance with the height setting determined by the matching of a tee height indicator 3 h and the case reference 2 f arrow a in fig7 a 8 and 8 a illustrate a correlation between golf tee height settings and tee height indicators 2 f an advantage of the device 1 is that it permits repetitive settings at a repeatable given height this is important for consistent golf ball striking if a golfer finds that for his clubs and optimum performance is.
