Cobra S9-1 Pro D Drivers. Used by Camilo Villegas and Geoff Ogilvy. The cobra S9-1 Pro drivers have been design in close collaboration with Cobra PGA Tour Professionals, Cobra developed the S9-1 Pro Drivers to be a major weapon off the tee for extreme-ball-speed players. The advancements begin with our COR-boosting Hotter 9 Points face technology and continue with a lightweight carbon composite crown, swingweight screw, two face configurations (Deep & Shallow) and three loft options all of which are geared towards enhanced performance and customization. These drivers also feature a new clubface shape that transfers energy to the ball with maximum efficiency. And with tour-inspired clubhead and black finish, your customers will feel complete confidence starting with their first drive. The Cobra S9-1 Pro D model is designed for players with a swing speed of more than 104 miles per hour and will produce a much lower ball flight compared to the Pro S Version. This club is specifically design for the more accomplished golfer who wants maximum control over their tee shots.
