Lashen says a proper fitting should start with an earnest discussion between the golfer and the club fitter. The conversation should reveal what the player is looking to accomplish with their golf game and include how often they play, their handicap, and the problems they typically encounter on the course. This will help provide a base line with their current clubs. Lashen adds that it may be determined that you can't do better, so there’s no need for new clubs.
The available technology to help determine the many elements of a set of clubs, is tremendous. But if the fitter does not have a full understanding of the technology, it doesn't help.
Compounding the problem is that certification of club fitters is inconsistent and unreliable, which leaves word of mouth as a key resource to find a reliable one.
“Club fitting is part technology and part art," Lashen says. "We have found that for the men and women who come to us, their club fitting goes a long way to help them increase their enjoyment of their time spent with friends and business associates on the golf course."
