The present invention contemplates an improved indicator for use in combination with a golf putter to provide improved putting performance by giving the golfer a point of focus on which to concentrate during putting, and by indicating whether the putting stroke is on or off line. The indicator includes a fluid filled container with a transparent face, and a ball or similar element movably disposed in the container. The container is fixed atop or adjacent to a putter head in a manner that a center line therein, which is visible through the transparent face of the container, is centered with respect to the putter head and extends at a right angle to the putter face.
