The Insight XTD is designed to give golfers maximum ball speed from centre and off-centre strikes, drawing on Adams' Boxer Technology, a geometric shaping system the company has also used in its hybrids. The Boxer Technology ‘pushes mass away from the face and into the corners for higher MOI', while the club also comes fitted with the Aldila DVS shaft. Designed for golfers with mid to high swing speed, the XTD a3 is the official driver of the Long Drivers of America, while the a3 OS is made for slower swing speeds. The a3 comes in 9.5, 10.5 and 11.5-degree lofts, with the a3 OS in 10.5 and 12.5 degrees.
