Abstract: To analyze golf strokes, the disclosed device has a mat assembly and a console, the mat assembly preferably including an electrically conducting base plate, mat, artificial grass, tee and eight special switches. The switches are arranged one behind and another in front of the tee, with the other six forming an oblong rectangle extending along the path of the stroke from somewhat behind to well in front of the tee, with four of them at the corners of the rectangle and the other two half way along its long sides. The analysis includes a for evaluating a golf club swing, which method compares "I" with "II", "I" being the time it takes for a swung gold club head to travel from a first pair of the six switches (actuated just prior to passing the golf ball position) to a second pair of the six switches (actuated just past the golf ball position) and "II" being the time it takes for the golf club head to travel from the second pair of switches to the third pair of the six switches.
