A tubular casing is held on a pad; through an elongated slot thereof extends a tee stem which supports a golf ball; a reciprocating tee bar inside the tubular member supports the tee stem on the bar so that when the ball is struck the bar is advanced against the action of a coil spring which latter returns the tee bar and the ball into an initial position; spaced from the tee bar is an indicator bar in the tubular member held in an initial position by a coil spring in the far end of the tubular casing and it has an extension projecting beyond the end of the tubular casing provided with indicia for indicating the distance corresponding to the force of striking the ball; a releasable pawl and ratchet device holds the indicator bar in extended position; the point of the tee bar is offset toward the slotted top of the casing so that when the ball is hit to one side or the other it turns the tee bar thereby reducing the force of impact on the indicator bar and also moving side flaps or plates for indicating the direction in which the tee bar was turned.
