The latest addition to Callaway's expansive Big Bertha family is the Mini 1.5 driver, which is now available at retail.
 
As its name suggests, the Mini 1.5 is smaller than a standard driver but bigger than a typical fairway wood. Specifically, its head is 235cc, making it about half the volume of a standard 460cc driver head but 35 percent larger than Callaway's XR fairway wood.
 
Callaway bills the Mini 1.5 as a new type of weapon off the tee for players of all swing speeds. Its size and construction make it capable of generating more ball speed than typical 3-woods, while also making it more forgiving than than many drivers.
 
 
The club contains Callaway's Forged Hyper Speed Face Cup and a Forged Composite crown, both of which are bedrock features in Callaway's best drivers. The crown is strong and lightweight, and allows Callaway to move extra weight to the clubhead's perimeter for more stability and forgiveness. The Face Cup, meanwhile, flexes more than other clubfaces, especially on shots hit low on the face, and boosts ball speeds over a larger area of the face.
 
It also has a cambered Warbird Sole to make it easy to hit off the turf as well as off the tee, as well as a shaft that is 44 inches long – two inches shorter than a standard driver shaft. And it features an OptiFit Hosel that lets golfers choose from eight different combinations for their loft and lie angle configurations.
 
The Bertha Mini 1.5 is available in 12- and 14-degree lofts, and carries a suggested retail price of $299.99 per club. Here's a video from Callaway about the club:
