Duncan now has the latest in club fitting technology GC3 that can measure all the principles of club fitting from clubhead speed, face angle, lie angle, shaft lean, attack angle plus more. This new device allows Duncan to 'fit' you correctly for your new driver, irons, putter etc.
One of the biggest influences in club fitting is the ball. Because golf balls are all so difference (dimple patterns, compression, construction etc) using different types of balls will give you different readings or results. In 'true' club fitting you need to visually see the ball flight, how the ball reacts through the air and when it makes contact with the ground. This is because certain weather conditions like air temperature and humidity have an influence on ball flight.
So when your next at the club pop in to the Pro Shop and see Duncan about club fittings.
