Abstract: A visual alignment device made of any appropriate high impact material that may be readily attached as a temporary training device or bonded as an integral part of many existing putter type golf clubs that assists the player in visualizing the putting line, in positioning his eyes over the putting line, and in properly aligning the putter head with the ball to be struck and in maintaining that alignment throughout the stroke. The top half of the device consists of a hollow hemisphere of the same diameter as a golf ball containing a sighting slot running substantially across it from the front to the rear and a number of small holes that simulate dimples in the ball and also allow light to enter the device.
