Swing Arc, the Golf Shop That Hangs a Pendulum

Field notes

The service records more than a generic swing-speed or fitting measurement: its sample card names the club, crest timing, through-side beat, and a trough four centimeters past the ball. The page describes a paper bob hung from the shaft, with separate readings for the swing’s high and low points. It also frames the analysis around local conditions such as Chippewa wind, January play at Half Moon, and seasonal differences between Phoenix Park and Water Street.
