1. A system determining a golf club head impact location based on magnetic field readings, the system comprising:
a golf ball comprising a microcontroller, a wireless transceiver and a magnetometer;
a golf club;
a mobile device in communication with the golf ball;
wherein the microcontroller is configured to measure a magnetic vector for a plurality of axis of a magnetometer within the golf ball while the golf ball is at rest;
wherein the microcontroller is configured to determine a magnetic orientation of the golf ball;
wherein the microcontroller is configured to measure the magnetic vector for each of a plurality of axis of a magnetometer within the golf ball at impact with the golf club head; and
wherein the microcontroller is configured to calculate an offset of the impact from a difference between the magnetic orientation of the golf ball and the magnetic vector at impact;
wherein the transceiver is configured to transmit the offset calculation to the mobile device for display; and
wherein the offset determines a signature for one of each of a plurality of golf ball impact locations.
