A golf swing training aid adapted to have a first rail and a second rail whereby a carriage system is slidably attached thereto and the pitch of the club is controlled with respect to the position of the carriage assembly in the course of a swing. The system is arranged to determine from the samples the position of the pen strokes. The method further requires scanning with a tracking system captured images stored a memory for the profile marker, and providing one of a visual alarm and an audible alarm indicating that the number of captured images containing the profile marker is less than the profile ratio. Several embodiments of this structure and methods to fabricate the same are also described. An image-processing unit is furthermore designed to create a digital representation of the object from said electrical charges.
