1. A system for improving a swing comprising:
- means for transmitting an electromagnetic field aligned with respect to a desired swing plane of a sporting implement, wherein said transmitting means comprises a transmitting coil which is aligned with the desired swing plane,an electronics package attached to said transmitting coil; and
means for detecting an actual swing plane relative to said desired swing plane, wherein said detecting means comprises three orthogonal coils and said electronics package measures the transmitter signal sensed by each of the coils and compares an amplitude of a signal generated by a first one of said coils having an axis pointed down a shaft of the sporting implement to a sum of a signal amplitude of a second and third ones of said coils and generates a signal in the form of a ratio indicative of an angle of the shaft of the sporting implement relative to the desired plane angle.
