发明名称 Golf swing practice club with laser pointer
摘要 A practice golf club that is short for carrying in luggage, but is weighted to a standard D3 swing weight. It has a shaft with first and second ends, with a first grip on the first end, a second grip on the second end, and a head projecting transversely from the second end for visual alignment of the club. It has a laser beam projecting from the second end of the shaft along the axis of the shaft. The golfer grips the first end of the shaft and swings the practice club, causing the laser to trace a line on the floor that provides feedback about the lower part of the swing. The golfer grips the second end of the shaft and swings the practice club, causing the laser to trace a line on the floor that provides feedback about the upper part of the swing. The golfer places the club horizontally across the thighs and observes the laser dot near a target to square the address stance.
