== == You can carry as many golf balls as you want.
A tour pro would have around a dozen golf balls in there bag per round, just in case. But it is completely up to the player.
In Golf there is no limit to the number of balls used. Depending on difficulty of the course and a players experience one single golfer could use as many balls as they have in their bag at the start of play.
106 golf balls
356,000 million golf balls ;)
Approximately 5 golf balls could fit.
The R&A, which is the ruling authority for most golfing tournaments worldwide, maintains a list of balls that conform to tournament regulations. Many different coloured balls are included in this list - there is no rule that states a ball has to be white.
As many as you have in your golf bag.
