The dimples ensure the air follows a little more around the back of a ball in flight than it would if the ball had no dimples. This reduces the size of the 'wake' behind the ball and the ball goes further.
A golf ball with dimples will travel through the air approximately twice as far as a totally smooth golf ball.
What’s the science behind it?
You’ll hit your longest drives on golf courses in high altitude locations. That’s because the air is thinner and the drag is reduced even more. So, go find yourself a high altitude golf course and test it out!
