I use both the “SWINGCLICK “and the “TOUR TEMPO TIMER “ of JOHN NOVOSEL . The “SwingClick” is slower than the “Tempo Timer “ and you can’t adjust your tempo with it. Both are useful to train your brain. The advantage of the “SWINGCLICK ‘'” is it tells you when you have reached the top of your backswing and the finish of your through swing . I had a tendency to shorten my backswing and the SWING CLICK cured that defect . Thank you. Good job, well done!
