SMT Golf has recently released the SMT Golf DB Plus driver. This driver combines technology from both the SMT Indio and the SMT Deep Bore. The driver is specifically designed to increase distance and decrease the overall spin on the ball as it leaves the tee. The SMT DB Plus appears to be smaller than other clubheads in it’s class but it is in fact 460cc, larger than any other SMT clubhead available. It is also approved by the USGA.
