Golf Training Device with a housing, the housing enclosing a battery power source, a light source such as an LED, a microprocessor, a proportional light sensor, an audio transducer and a momentary on/off switch, a flat rectangular surface such as a sheet of thin plastic having a length equal to that of an average putters swing, the sheet coated with non-reflective material such as flat black paint, the sheet also having a centrally located narrow reflective strip attached to and traversing longitudinally along the surface of said sheet, said sheet being placed on the ground or floor during use said reflective strip being interrupted at regular intervals with non-reflective material, said housing being provided with an attachment means such as a magnet or hook and loop type fasteners to allow said housing to removably attach to the side of a golf club head, said LED aimed downward toward said reflective strip, said microprocessor capable of interpreting the closeness of said LED light to said reflective strip so that the amount of light received by said proportional light sensor controls the pitch or amplitude of an electronic audio oscillator circuit, producing an audio tone that varies in pitch or amplitude with the alignment of the light beam over said reflective strip, and said microprocessor also capable of interpreting the speed of said swing by sensing the time between said interruptions in said reflective strip.
