I was introduced to custom fitting in 1987 while serving as Education Chairman of my PGA Section. Twenty five years later I continue to emphasize the importance of properly fitted equipment to my students and customers.
We have all heard the saying, "It's not the arrow, but the Indian", but I can assure you if you're playing with antiquated or ill-fitted equipment you're at a distinct disadvantage. No two players possess the same physical stature or swing characteristics so why would we assume they should be using the same equipment? It simply makes no sense. You wouldn't buy a suit off the rack without trying it on, nor should you invest in new equipment without being custom fit.
At Golf Rx I only offer custom fitted golf equipment to my students and customers, and in my opinion this is the only way professional golf equipment should be sold.
