twest,
there is no national USSSA rule that prohibits an indicator/clicker/thingy...
OSSAA is the Oklahoma organization that oversees HS athletics. It is a member of the National Federation of State High School Associations. Their rulebook is commonly referred to as "FED"
Major League rules are officially called the Official Rules of Baseball or OBR.
USSSA uses OBR as it's base set of rules. However, they have adopted some of the FED rules specific to safety. In addition, USSSA has published national rules on it's website,

My suggestion, FWIW, chalk this one up to stupid board members. Always ask the tournament director about any tournament rules. Come play ball in Northwest Arkansas. You get a quality tournament and umpires that can work.
