In last week's issue of GolfWeek, James Achenbach breaks the news that the USGA and the R&A are set to bust up one of the dumbest rules in modern-day golf: rule 14-3b, the "range finder rule."
The rule currently prohibits a player from using "any artificial device or unusual equipment for the purpose of gauging or measuring distance or conditions which might affect his play." This includes range finders, which are artificial measuring devices.
The stupidity of this rule was, of course, not always evident. Golf existed long before yardage markers and yardage books. However, with many courses publishing yardage books or marking sprinkler heads, the rule has become long in the tooth.
