Prior to your custom fitting, your fitter will ask questions regarding your golf tendencies such as hitting the ball too high, too low, or to the right or left. Static measurements obtained include your height, hand size, and wrist to floor measurements. You can tell your fitter if you have brand loyalty or preference.

The GCQUAD will be used to obtain multiple ball and club data points. Your custom fitting recommendations will be based upon the multiple data points obtained. Your fitter will determine optimal swing weight, loft and lie angles, and shaft length.
