Has anyone had this problem with the swing meter being blank meaning no marks at 25%,50%,75% this problem happened last week then all was good for a couple of days then yesterday problem started again.
That graticule (word of the week) that you no longer have, is applied to the swing meter by the putter/shot pals. These come free when you are a member of a country club that is level 4 or above. If you have recently left a country club, that may be the reason you no longer have the graticule.
You can purchase the 'pals' from the pro shop if you wish to remain outside of a country club and still have the graticule, but they have a limited duration. Whereas inside a country club, they are immortal.
