Abstract: Methods, systems and apparatus for golf swing analysis are disclosed. One golf swing analysis system includes a motion sensing device attached to a golf club, the motion sensing device comprising a controller and one or more motion sensors. The golf swing analysis system further includes a remote processor, wherein a wireless link electronically connects the remote processor and the controller of the motion sensing device. Further, at least one of the controller and the remote processor are operative to access sensor data generated based on sensed signals of the one or more motion sensors, and perform pattern recognition analysis on the sensor data, comprising identifying and analyzing at least a portion of a golf swing based on the sensed data.
