The Callaway Big Bertha Diablo driver is an incredibly fun club as it has a huge sweet spot, making it almost impossible to slice or hook, whilst gaining some serious distance down the tee!
Callaway have designed this to be a monster on the golf course! The Hyperbolic Face Technology significantly imporves ball speed across the driver's face, generating more distance - even on off-centre hits. Designers have redesigned the clubhead to help golfers square the clubface at impact and hit it straight! The Callaway Big Bertha Diablo has striking graphics and will appeal to golfers who want to be seen and heard!
The fiery red finish won't be to everyone's liking, but it certainly floated our boat. But it was only when we hit it that we realised how much fun this club was.
Basically, it features the massive sweetspot that we have come to expect from Callaway, but it also has something else...accuracy. The manufacturer reckons that Diablo is ideal for those of us who like to "give it a rip" off the tee, and especially when we swing more aggressively than normal.
As for the physics, the Diablo benefits from 'Hyperbolic Face Technology', a design which helps to incrwase the size of the sweetspot, while the so-called 'Edge Technology' means the Callaway wizards have moved weight in the head to maximise MOI. All in all, this is a long son of a gun, and you won't be missing many fairways with it.
And if you like all your gear matching, you'll be pleased to hear there is also a fairway wood, a hybrid, irons and balls in the Diablo range!
Happy days!

Review from the magazine

2009, Updated Model – Review
This got some strange looks from the test team – Chris wasn’t a fan at all – but all four guys loved the performance. Jon gave it full marks in every department apart from looks and also sent one out to 247 yards – one of his longest. If you like a driver to make a definitive thud at impact, this is your baby. Oh, and it comes in a Draw version too – perfect for slicers everywhere!
