1. A putting training aid and calibration device for use on a substantially horizontal and planar putting surface, for use in calibrating a putter having a shaft and a head, with said head having a sole and a face, with said sole and said shaft defining a lie angle and with said face, and said shaft defining a loft angle, the training aid and calibration device comprising:

  • an elongated rigid calibration member having a first end and a second end and supported above and parallel to the putting surface;

    a first linear scale indicated on said calibration member intermediate said first end and said second end;

    a second linear scale affixed to said shaft;

    wherein said lie angle is determined by resting said puffer shift on said elongated rigid calibration member, in contact with said first linear scale and by parallelly placing said sole on the puffing surface; and

    ;

    wherein said loft angle is determined by resting said puffer shaft on said elongated rigid calibration member in contact with said first linear scale, and by orthogonally aligning said head face to the putting surface.
