Practice swings are moments of rehearsal and awareness.
During these swings, golfers naturally check whether the club matches their intended position. They are not trying to change mechanics — they are confirming orientation.
A visual reference allows this confirmation to happen clearly and consistently. Instead of relying on feel alone, golfers can visually confirm whether the club appears the same from swing to swing.
This supports the work golfers do with coaches and during practice without interfering with instruction. Visual confirmation simply provides clarity during moments of awareness.
