Abstract: The device is an improved base support for securing yardage indicating number inserts or a flag holder insert and an attached flag to a sprinkler unit installed on a golf course. The improved base support is secured to the sprinkler unit by means of a base. The flag insert and attached flag are installed on the base during construction of the golf course to prevent operators of heavy equipment from hitting or running over the sprinkler unit. Once the golf course is completed, the flag holder insert is removed from the base and replaced with the yardage indicating number inserts. The flag holder insert and the number inserts are provided with beveled sides and ends. The beveled sides of the flag holder insert and the beveled ends of the number inserts slide between base tracks provided on the base in order to secure the inserts to the base.
