Here at Woody's we use PING's nFlight fitting system. In creating nFlight, the company's team of software developers, scientists and fitting experts combined years of product knowledge, scientific data and fitting research into a tool that ensures fitting results never before available in both the indoor and outdoor environments. It factors in the golfer's typical playing conditions to compensate for any environmental variances. It even considers the type of ball you're being fit with to ensure accurate results. In addition to providing detailed club specifications, nFlight includes a gapping analysis feature to make full set recommendations. By analyzing data from three clubs hit during the fitting session – typically a hybrid, iron and wedge – the software configures a set to produce proper distance gaps between every club. In the end, you walk away with complete confidence in the PING Custom Fitting process knowing you've been properly fit for the latest advancements in equipment technology.
