In rec games I tend to use one but not in scholastic games as my association does not allow it at that level. In Chucks post he talks about using a spare whistle or mint. Like his D1 assignor, I find that to be most unprofessional. Hay, why is that ref digging in his pants?

The question does need asking, If baseball umpires can use clickers why cant basketball officials use something?
