Abstract: A golf stance alignment device is a practice apparatus for insuring that a golfer takes the proper stance when addressing the ball. The device is adjusted to touch the golfer at the shoulders and just below the knees when the golf club is placed in the marked position for the particular club being used and the golfer takes up position as if to hit the ball. The device is adjustable in extension and angle according to the golfer and the club being used. Graduations on the device enable it to be reset with the same angles and lengths for repeated practice sessions. After standing against the device, the golfer then steps away, takes up the same stance, and plays the golf ball while remembering the stance from the correctly aligned position previously supported at the shoulders and knees by the device.
