If you golf like us (occasionally and poorly), teeing off means swinging hard and hoping for the best. But CALLAWAY 's BIG BERTHA DIABLO DRIVER offers damage control. The three-piece titanium head uses a hyperbolic facethicker in the middle, thinner at the edgesto deliver long drives even on off-center strikes. Designers also tuned one model to fix your slice. $199; callawaygolf.com
