Abstract
An apparatus for practicing a method of determining the effective putter loft of a golf putter as swung by a particular golfer in which the putter has a curved face unit placed on the hitting surface and the putter is then swung by such particular golfer against a hitting cylinder. The location of impact between the curved face and hitting cylinder provides data from which the effective loft can be determined.
