Abstract
A golf putting device which provides immediate feedback on eye positioning relative to the golf ball. The system is completely passive and does not interfere with the golfers putter, hand position or natural set-up. Two small plano mirror are mounted perpendicular to one another on an L-shaped base. The first mirror is mounted on a fixed inclined base, faces the golfer, and ensures forward-backward eye positioning. The second mirror is mounted on an adjustable tilt base, is to the right of the golfer, and ensures inside-outside eye positioning. The collimated reflection plane of each plano mirror intersects directly above the golf ball. A pivoting arm positions the golf ball directly below the reflection intersection plane. A guide rail is provided to ensure the stroke remains along the intended line.
