A device for a golf club for instructing club face orientation for a selected swing speed including a body with a selected thickness and such that a substantially pointed forward end thereof intersects a midpoint of the club contact face and in a perpendicularly extending direction relative to a coplanar axis extending across the club contact face. An adhesive tacky material applied to an underside surface of the body engaging the body to a top surface of the club head. A processor communicates with an inertially sensitive cam shaped member rotatably mounted within a location of the body. A swing speed adjustment knob is in operative communication with the body and in contact with the inertially sensitive element via an adjustment spring. An audio-generating transistor and a plurality of LED elements cooperate with the processor for instructing a correct planar orientation of a contacting face of the club head relative to the golf ball.
