Abstract: Swing starter (1) comprising a straight target rod (2) and a curved rod (3)interconnected by a web (4). The curved rod has a radius of curvature of about 1.55 m and a length of about 0.6 m. The front portion (5) comprises a convex mirror (6) having a indicator line (7) parallel with the target line. The swing starter is placed on the ground having a pin (9) thereof extending down into the ground. The pin allows the swing starter to be pivoted under friction around an axis parallel to the target line. The golfer places himself beside the swing starter opposite the front end (5) thereof. The swing starter is pivoted until a convex mirror (6) positioned at the front end of the curved rod indicates the correct swing plane has been achieved by viewing the shoulder portion of the golfer at a line (7) of the mirror. The upper surface of the curved rod may be provided with a color, e.g., red, differing from the color, e.g. white, of the remaining portion of the device.
