A plurality of linear sighting marks on the club face of a golf club, each mark being disposed at a different acute angle with respect to the lower edge of the club face and each mark being arranged on the club face at a location to cause the club face to assume a different angular relation to a vertical plane extending therethrough when the club head is positioned, respectively, to orient each mark in perpendicular relation to the intended line of travel of a golf ball struck by the club face, whereby the loft and distance of travel of the golf ball may be selectively varied.
