I am just wondering if anyone has found a spray powder in Australia to record the ball strike on the club-face.
US teachers talk about Dr Scholes foot odour spray but the one they use called X-Odour does not seem to available in Oz. The ones that are available dry clear and probably won't do the job.
I currently use a dry erase marker and it is ok but a bit tedious.
I am interested to hear about something that works.
I have attached a screenshot of a good example.
Thanks in advance.
