Abstract
A putting training aid and putter calibration device for use on a putting surface is disclosed which includes a horizontal calibrated bar with a linear centered scale and a parallel calibration block having an oblique face and set on the practice putting surface below and offset from the horizontal calibrated bar. Also provided is a linear scale decal which is applied to a putter shaft. The device is designed to align the putter head to proper lie and neutral loft so that the face is square to the intended target line and to teach the golfer the proper grip, stance, alignment of the golfer, alignment of the club and proper putting stroke.
Claims7
A putting training aid and calibration device for use on a substantially 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, comprising:
- an elongated calibration member having a first end and a second end and supported horizontally 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 adapted to be affixed to said shaft;
- whereby said lie angle may be determined by resting said club shaft on said elongated calibration member, in contact with said first linear scale and said sole on the putting surface;
- and said loft angle may be determined by resting said shaft on said elongated calibration member in contact with said first linear scale and aligning said head face oblique to the putting surface.
A putting training and practice aid for use in training a golfer's putting stroke along an intended target line on a substantially planar putting surface with a putter having a face and a shaft, said training aid comprising:
- an elongated guide member having a first end and a second end and supported horizontally above and parallel to the putting surface and horizontally offset from said intended target line;
- a ball marking spot defined on said putting surface and intersected by said intended target line;
- whereby a repeatable putting stroke may be practiced along said intended target line by placing a golf ball on said marking spot, resting the shaft of a putter on said guide member, addressing said ball, aligning the shaft with said guide so that the intended target line is normal to the face of said putter and practicing the putting stroke with the shaft remaining in contact with the guide member.
