1. A golf club head module configured to be attachable to and detachable from a golf club head, the golf club head module comprising: a circuit configured to measure receiver signal strength of a received radio wave signal along a non-linear travel path of the golf club module, the radio wave signal being received from an external device, the signal strength being measured at least at first and second times along the club head travel path; at least one sensor configured to measure additional attribute data along the non-linear travel path of the golf club head module at the first and second times, the additional attribute data including at least one of optical signals, magnetic fields, electric fields, acceleration, and orientation changes; and a transmission device configured to transmit synchronous time-aligned receiver signal strength and additional attribute data for the first and second times to the external device for analyzing the non-linear travel path of the golf club head module.
