A golf club head for a putter or the like having a sighting device by which the golfer may easily align the club head to maintain its horizontal plane parallel with the putting surface. The sighting device is a cylindrical cavity in the club head immediately behind the point on the club face at which the ball is struck. A light colored spot is concentrically disposed on the lower closed end of the cavity. A transparent disc is disposed over the upper open end of the cavity and has a concentric dark spot concentric therewith. The golfer establishes a vertical line of sight with respect to the ball and adjusts the plane of the club head to cause the lower spot to be in coincidence with the upper spot. The sole plate of the club head is relieved to the rear of the club face to minimize dragging and scuffing on the grass of the putting surface during a stroke. Recesses in the relieved areas are adapted to receive selectable size weights which permit the weight of the club head to be adjusted to suit the individual and to also balance the head or to vary the heel-to-toe weight ratio.
