Abstract:
1. An adjustable golf club comprising: a shaft sleeve comprising a shaft-receiving bore and an external surface having a first reference marking; a tubular adjustment piece comprising an external surface having a positional marking and non-parallel upper and lower surfaces, the tubular adjustment piece encircling at least a portion of the shaft sleeve; and a golf club head comprising a hosel, the hosel comprising a hosel bore and an external surface having a second reference marking, at least part of the hosel bore having a diameter sized to receive at least a part of the shaft sleeve, wherein when at least part of the shaft sleeve is disposed within the hosel bore, rotating the tubular adjustment piece around the shaft sleeve changes an angle of the shaft sleeve with respect to the hosel, creating a plurality of different angular settings, wherein the first reference marking and the second reference marking create a reference frame readable by an electronic device, wherein each angular setting correlates to a unique readable code formed by the first reference marking, the positional marking, and the second reference marking when viewed within the reference frame, and wherein the electronic device is configured to analyze the readable code, associate the readable code with its correlated angular setting, and display the loft and lie angle of the golf club head.
