Powerbilt Air Force One Air Foil Driver The Powerbilt Air Force One Air Foil Driver is new and improved for 2010. The PowerBilt Air Force One Air Foil is the golf only club on the market with Nitrogen Charged Technology, a patented process that involves filling the club head with nitrogen gas to provide weightless support of the face. This allows PowerBilt to build drivers, fairway woods, hybrids and now irons with the thinnest faces in golf without internal bracing. The benefit is greater distance plus improved accuracy due to an enlarged sweet spot. f player, src videosflowplayerflowplayer.commercial 3.1.5.swf, cachebusting true, key '450d1f2cfdf440be091', clip url httpwww.intheholegolf.comvideospowerbilt air force one air foil driverpowerbilt air force one air foil driver.flv, autoPlay false, autoBuffering true The original PowerBilt Air Force One Driver was a huge success in 2009, and for 2010, PowerBilt has made imporvements on that technology in the new Air Foce One Air Foil Driver.
