Abstract

Fixed markings 20 are a teaching aid made by permanent placing of marks on another teaching aid. Golf lessons are frequently given with the assistance of teaching aids. Teaching aids are used by the golf professional 30 to point out to the golfer 26 many of the factors and positions involved with the golf swing. One of these teaching aids is a full length mirror 10 used to visualize the golfer 26. The mirror is held in a frame 12. The other teaching aid is reference lines 16. Reference lines 16 are best described as cords by which the professional is able to locate different positions of the golfer on the mirror. Reference lines 16 are held in place over the mirror by clips 18 on the ends of the reference lines 16. The clips 18 are attached to the mirror frame 12 over or in between the fixed markings 20. Fixed markings have been permanently placed around the front of the entire perimeter of the mirror frame 12. Fixed markings can be numbers and letters. The numbers and letters around the perimeter of the frame are about 3/4" high. There is about 11/2" between the fixed markings. Letters identify the sides of the frame: T-top, B-bottom, L-left, R-right of frame. The position of the clips 18 on the frame 12 in between or over the numbers and the side location of letters can be recorded. Recorded clip positions give the reference line 16 position over the mirror 10. Without the fixed markings teaching aid there is no way to record golf lessons given using the other two teaching aids. By using fixed markings golf teaching aid a permanent record FIG. 3C can be made and written down.
