Before any golf club from a major manufacturer hits the shelves to be picked up and bought by amateur golfers it goes through a rigorous testing schedule on Tour - and none more so than Titleist equipment.
The company have just shipped a number of prototypes of their new 712 iron range to their army of players on the PGA Tour where they will go through what Titleist call a "Tour validation" process.
The irons include the new 712 MB's, 712 CB's, 712 AP2's and 712 AP1's and before Titleist will commit to putting these irons on sale to the general public, they insist on getting feedback from the very best players in the world.
They were introduced to players ahead of the AT&T National at Aronimink last week and straight away 19 players put the irons into play in competition, including eventual winner Nick Watney using the AP2's.
Watch the video below with Chris McGinley, vice president of Titleist golf club marketing, Chris Tuten, director of Titleist tour promotion and Marni Ines, director of Titleist iron development to find out more about their Tour validation process.
