It depends on the student

Having been a PGA PROFESSIONAL for 20+ years, the answer for me is that it depends on the student. A serious player is yes, the more information regading launch angle, spin rate, path, swing speeds on all clubs, carry distance, etc., is extremely vital. For the majority of players, the answer is also yes!!! These are absolutely invaluable for an expert club fitter like me. It will show what weaknesses there are, where my teaching should focus, and sets me up a pathway to help my clients/customers fast track to improvement!!! Absolutely very important!!!
