Abstract: The invention is an alternative fitting system for golf clubs including an adapted production head with a threaded hosel and a shaft sleeve adapter and a compression nut. The shaft sleeve adapter is permanently adhered to a golf club shaft. The compression nut holds together the shaft sleeve adapter and the threaded hosel of the club head. Alignment notches on the threaded hosel and alignment features on the shaft sleeve adapter prevent unwanted rotation. Furthermore, some embodiments of the shaft sleeve adapter comprise an angled bore hole, which allows for various loft and lie configurations.

Abstract: Disclosed herein is an electronic device holder comprising a body having a back portion, a first body end, a second body end, and a first and second side portion. The device holder further comprises a clamp on the back portion of the body that is configured to removably attach and secure the body of the electronic device holder to a golf club shaft. The clamp comprises a first and second arm portion each comprising a support portion, an arcuate portion, and a guide portion. The guide portions assist in aligning and inserting the electronic device holder onto the golf club shaft. Furthermore the first body end, the first side portion, and the second side portions of the holder body comprise curved portions that assist in securing the electronic device into the holder. Other embodiments and systems are described herein.

Abstract: Described herein is a golf club head having a body and a high density metal piece integrally embedded within the golf club head body, wherein a gap is disposed between the exterior surface of the high density metal piece and the exterior of the golf club head body and a method of manufacturing thereof.

Abstract: Embodiments of systems, methods, computer-readable media and article of manufacture related to measuring, analyzing, and sharing golf swing and ball motion characteristics are generally described herein. Other embodiments may be described and claimed.

Abstract: Embodiments of systems and methods for fitting golf club head weight are generally described herein. In some embodiments, a system to analyze tempo data comprises a tempo analysis module configured to run on one or more processors, and is further configured to receive swing data from a tempo sensor. In many embodiments, the swing data comprises a backswing time and a downswing time. The system is further configured to generate a tempo ratio comprising the backswing time over the downswing time. In many embodiments, the system comprises a golf club head weight analysis module configured to run on the one or more processors. The golf club head weight analysis can be further configured to generate a recommended golf club head weight determined by at least the tempo ratio.
