Abstract: A golf club simulation apparatus includes an elongate shaft housing having opposed lower and upper ends and defining an interior area. A club head member is coupled to the lower end of the shaft housing. A battery is situated in one of the club head member and the shaft housing. An input member configured to receive club selection data is coupled to an outer surface of the shaft housing and electrically connected to the battery. A mass variability assembly is electrically connected to the input member and includes a weight member situated in the shaft housing that is selectively movable therein according to the club selection data. An electronics module having an angular sensing sensor is situated in the club head member. A bend variability assembly is included in the shaft housing for selectively altering a “feel characteristic” of the shaft housing during a swing motion.

Abstract: A golf club simulation apparatus includes an elongate shaft housing having opposed lower and upper ends and defining an interior area. A head housing is coupled to the lower end of the shaft housing. A battery is situated in the shaft housing. An input member configured to receive club selection data is coupled to an outer surface of the shaft housing and electrically connected to the battery. A weight indexing assembly is situated in the head housing that includes a tumbler rotatably coupled to the lower portion of the shaft housing and that includes a weight carriage situated in the club head housing. The tumbler has an outer surface defining an indexed slot network, the weight carriage being in communication with the indexed slot network and configured for movement along the indexed slot network in a gravity assisted movement.
