Doublewall 360cc Driver (LH)

The Doublewall(TM) has been independently tested to have the "Biggest Sweet Spot" in golf. It is engineered with a patented inner wall dramatically improving performance. This revolutionary new technology creates an extraordinarily strong power chamber improving C.O.R. over the entire hitting surface of the club. The result is your off-center hits perform almost as well as your dead center hits. Light weight, yet extremely strong and stable, the woods abandon the "trampoline effect" technology recently adopted by most other golf club manufacturers. Instead, it achieves its performance by building the "solid concrete floor" from which the Doublewall achieves it's performance. The design is engineered to achieve the largest, most stable sweet spot in golf at the highest COR allowed by USGA Rules. BioMechanica, an expert biomechanical engineering firm that provides counsel to the USGA and builds the golf club testing cannons that are standard in the golf industry, was hired to test the Doublewall technology. The test results are amazing. BioMechanica found that the hitting the Doublewall off-center (like most of us do) will only decrease your performance by 2.9%. That's 18% better than the nearest competing club for off-center hits! BioMechanica's independent lab tests showed some extremely interesting results. Because the Power Chamber in the DoubleWall creates a more stable striking face, all of the independent testing lab results showed the DoubleWall had a much smaller standard deviation of COR for off-center hits than any club it was tested against. And the differences were significant. That is what BioMechanica’s test reports showed us. We were thrilled, because all of that technical jargon translates as - a Bigger, Fatter Sweet Spot! Now, not only does the DoubleWall play at the edge of the legal speed limits, it does so more consistently throughout the face area of the club head. This is a very big deal for those golfers who don’t always hit the ball dead solid perfect. And you know who those guys are — pretty much everybody! This patented driver (made in the USA; 2009 model) clearly deserves to be called a premium driver. A free headcover is included.
