An assessment is the only logical way to find out where you are with all elements of your game at any point in time (technically, mentally & equipment wise), and to find out what can be done to bring about improvements, or which program would be most suitable for you to follow.
Do you know what distances you really hit each club in your bag on average and what the real gapping is between all your clubs? Would you like to compare how different settings on your driver affect your average distance? Would you like to compare different clubs/shafts? Or do you just want to see on black & white how effective certain things you are working on at the range really are?
You can get all the answers by coming for an assessment on FlightScope, the launch monitor that can literally measure your performance and that of your clubs.
