1. A golf club, for measuring the force of a golf swing and the distance a golf ball will travel after being hit by the golf club, comprising:

  • a club having a first end having a handle portion, a second end having a club head, and an elongated shaft located between the first end and the second end of the club, wherein the handle portion and the shaft are at least partially hollow, said shaft having an external surface and an internal bore, and a plurality of longitudinally arranged circular openings which extend fully from the external surface to the internal surface of the shaft;

    a distance-determining mechanism, for allowing the user to gauge the force of a swing, and also the distance that the golf ball would travel if it were hit by a swing of similar force, said distance-determining mechanism having a selectively movable marker barrel, an attached distance rod, and an associated main spring, wherein the marker barrel and attached distance rod move toward the head of the club when the golf club is swung, and thereby displace the main spring from its pre-swing position to a post-swing position, wherein the position of the marker barrel within the shaft after the club has been swung is determined by the main spring and may be readily viewed through at least one of the plurality of longitudinally arranged circular openings within the shaft, and wherein the position of the marker barrel within the shaft indicates the particular force of a swing, and also the particular distance that a golf ball would travel if hit by the force of said swing; and

    a release mechanism, for selectively immobilizing the distance-determining mechanism, said release mechanism having a “

    release”

    position wherein the distance-determining mechanism is free to move within the shaft, and having a “

    lock”

    position wherein the distance-determining mechanism is immobilized within the shaft, wherein the release mechanism is “

    locked”

    before the swing of the club and thereby holds the distance-determining mechanism immobile, the release mechanism is momentarily “

    released”

    during the swing of the club, in order that the distance-determining mechanism may move to its post-swing, extended position within the shaft, and then is immediately locked following the swing to maintain the marker barrel in said post-swing, extended position.
