Visual impact detection golf teaching system

A teaching putter golf club comprising

• a club head having a club face and a club top surface;
• more than one piezoelectric sensor element embedded in said club face surface so that a flat, planar club face surface results said sensor elements parallel to said club face and arranged so that at least one sensor element covers a club face preferred impact center;
• an elastomer cover having a smooth outer surface designed to make contact with a golf ball and a grooved inner surface, said grooves defining shapes large enough to cover underlying piezoelectric sensor elements, said elastomer cover designed to cover and protect said club face surface;
• an electrical circuit printed on a circuit board placed within said club head;
• said printed circuit enabled with means for detecting a golf ball impact location on said club face;
• said electrical circuit having light emitting diode (LED) visual output means, each piezoelectric sensor element similarly wired to an individual LED so that a golf ball impact on a single piezoelectric sensor results in a single corresponding LED colored output signal and a golf ball simultaneously impacting on more than one piezoelectric sensor results in more than one simultaneous corresponding LED output signal;
• said piezoelectric sensor element wired to said LED comprising a voltage regulator controlling an electrical circuit transistor to transistor voltage, an operational amplifier connected in a differential mode open loop for high sensitivity, resistors limiting current input from said sensor element and from a power supply, resistors and a voltage divider that adjust inverting voltage input when said sensor element is undisturbed so that said operating amplifier voltage is high enough to maintain a chip logical HI of a first NAND gate and a set/reset latch, with a reset pin that is HI so that said latch output is LOW and said LED is turned off until said operating amplifier provides an output in a range of logical LOW that results in an output of said set/reset latch to turn HI which, limited by a resistor, turns on a transistor and said LED, said electrical circuit remaining latched in said HI position so that said LED remains on without said sensor element stimulation until a user presses a reset button and said latch is reset,
• more that one aperture in said club top surface;
• said LEDs received by said apertures;
• said number of apertures equaling said number of LEDs and said number of piezoelectric sensor elements, said apertures arranged in a pattern the same as said piezoelectric sensor elements' pattern;
• a resilient elastomer material having a grid pattered surface for said sensor element adhesion forming a sensor grid assembly with said piezoelectric sensor elements and said elastomer cover;
• a resilient, foam like material placed behind said sensor grid assembly which minimizes vibrations and intensifies an electrical signal generated by said club face impacting a golf ball;
• and
• a shaft having a distal end grip portion having a grip cap top with on off switch means and a grip cap side with reset switch means.
