The TEC Plus Ladies Ti Matrix Driver features a deep face and maximum C.O.R. (coefficient of restitution) design. C.O.R. is a measure of how efficiently energy, in the form of velocity, is transferred between the ball and the club head. Essentially, a maximum C.O.R. means that the club head has the largest, USGA-legal "spring-like" effect. The strong graphite shaft and titanium matrix construction provide forgiveness, allowing shots that are not hit in the center of the face to still remain precise. The TEC Plus driver delivers consistently high, long ball flights, and is the perfect club for anyone looking for an affordable driver.
