When buying Ping golf clubs, a fitting process determines the best specifications from which to build a custom set for a player. Every Ping iron has a small color-coded dot that identifies the relative lie angle. A black dot signifies a standard lie approximately in the middle of the range of available choices, and various other colors indicate different lie angles.
All Ping irons are custom fitted. When a golf shop sells a set of Ping irons, the sales person interviews and measures the player to determine the best specifications. For ordering on the Internet, golfers answer interview questions and take their own measurements to complete the fitting. This process ensures that the clubs have the correct dimensions, including length and lie angles.
The lie angle is the orientation of the shaft to the sole of the clubhead. Using clubs with proper lies is important for solid contact and the correct ball flight. Shafts are progressively shorter from the long irons down to the wedge, so the lie angles must change to keep the clubhead flat against the ground at impact. An iron set's lie angles use either the standard values for each numbered iron or are shifted a specific number of degrees upright (toe up) or flat (toe down) to fit a specific player.
One of the unique features of Ping irons is the color-coded dot. All irons are available with a specific shift to each club’s standard lie angle, and the dot identifies the amount and direction of the shift. There are 12 color codes in three-quarter-degree steps ranging from 3.75 degrees flat to 4.5 degrees upright.
The dot colors used to identify the lie angles, in order from the most flat to the most upright are gold, brown, orange, purple, red, black, blue, yellow, green, white, silver and maroon. The black dot signifies standard lies, neither upright nor flat, which are supposed to fit players of average size. Golf shops that sell Ping clubs have a chart identifying the codes and showing the proper color for different body dimensions. The chart is also available at the Ping website.
Older model Ping irons have their colored dots on the back of the clubheads, usually within the perimeter weighting cavity. On 2005 and later model irons, the dots are embossed in the hosel on the side away from the clubface.
