Abstract: A golf putter sighting device that includes a clamp that removably and adjustably engages the shaft of the putter with the clamp supporting a rigid outwardly extending body on which two laterally spaced sights are mounted. The clamp is adjusted on the shaft to a position where an imaginary line extending through the sights is normal to the striking face of the putter, and a substantial portion of the body between the sights is obstructed by the shaft when the user is in a putting position and looking down onto the shaft and head of the putter. When the sights are visible as equally spaced on opposite sides of the shaft, the striking face of the putter head is normally disposed to the direction of the swing of the putter head as the latter is used in putting a golf ball.
