A swing monitoring system in the form of a wrist mounted unit which includes multi-function instrumentation with extremely high degrees of precision that monitors a plurality of critical components of the swing of a golf club, tennis racquet, baseball bat hockey stick or the like. In particular, motion sensors that discriminate finite changes in the timing and speed of the swing are disposed in a housing mounted on a wrist bank analogous to a common wrist watch or timepiece. In addition, sensors are disposed in the wrist strap for detecting changes in grip pressure during the act of swinging any of the above mentioned equipment. The detected parameters are displayed on a LCD which is part of the instrumentation. Desired parameters can be saved in memory and the components of subsequent swing are compared to those saved, and if they are different, an audible alarm or signal is activated. The exactness of the subsequent trail swings relative to those saved in memory is a function of the handicap or other self designated indicator of skill level of the user.
