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
orthogonal 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
