“It’s likely that many golfers used in the data are still using five-plus-year-old drivers as well and most don’t get fit for their equipment to benefit from the advancements,” he said, noting that Golftec fitters have found distance gains by fitting players with one-inch shorter driver shafts (44.5 inches) that are more in line with lengths being played on the PGA Tour. Clearwater said those fittings have increased driving distance by almost 21 yards while producing shots that are eight yards closer to the center line.
