Yesterday Ben Crane was given two separate 4-shot penalties for starting his round with non-conforming clubs. The reason they were non-conforming is because they had those little white reflective stickers you put on to get club-face data from a GC2 launch monitor. Didn't realise this was a rule, and have seen plenty of people at my club (as we have a GC2 in the teaching bay) with the stickers on their clubs. Is this another of those funky USPGA rules? or is it something the R&A enforce?
