1. A training aid, including:

  • a housing;

    a clamp for releasably mounting the housing to an implement;

    a battery within the housing;

    a sound generator connected to the battery through an electrical circuit; and

    a force activated switch in the electrical circuit, which is activated to energise the sound generator to sound in response to displacement of the training aid,wherein the force activated switch;

    has a force threshold at which the force activated switch is activated to energise the sound generator to sound, andis configured so that the force threshold is user adjustable;

    and wherein the force activated switch comprises;

    a force sensor outputting a force voltage which varies depending on the displacement of the training aid;

    a user adjustable potentiometer outputting a force threshold voltage which is the force threshold; and

    a voltage comparator which is operable to compare the force voltage to the force threshold voltage,wherein the force activated switch is operable to energise the sound generator when the force voltage of the accelerometer is bigger than the force threshold voltage.
