What we say...

Callaway’s Big Bertha Irons are their easiest to launch distance iron

Callaway say the Big Bertha irons are their “easiest to launch distance iron”. Each has a hollow construction which along with a 360 Cup Face (which has a thin flexible rim to maximise ball speed) gives consistent, long distance, extreme forgiveness and a great impact sound. 

Big Bertha has long been associated with innovation and pushing technology boundaries, and Callaway reckon the 2019 model lives up to its name thanks to a brand new ‘suspended energy core’.

It, say Callaway, along with a three-piece construction allows them to position the centre of gravity deeper, to create a higher launch and thinner faster cup face. Make no mistake, it, like the original woods and irons are designed to be forgiving, and thanks to slightly weaker lofts (than Callaway’s strongest Rogue X irons) the Big Bertha is aimed firmly at the super game improvement iron market.

Callaway Big Bertha Irons: TG Verdict

Good looking, super game improver irons never used to be a thing, as old school designers thought golfers were willing to give up cosmetics for increased performance. The Big Bertha, though, shows how far the category has come. The BB’s head is created as a skeleton frame with parts attached to it, ensuring weight is positioned precisely to maximise playability from what is a head size we wouldn’t expect to see in this category.

Simon, who plays off 10, says he could happily play the Big Bertha, knowing its extremely forgiving body and slightly lighter weights would help with accuracy and power at his average swing speed. Like most irons nowadays these aren’t cheap. The PVD finish looks super sleek, too, on an iron more than worthy of the legendary Big Bertha moniker.

How does Callaway’s Supended Energy Core work? 

“It starts with a Metal Injection Molded (MIM’d) Tungsten Floating Weight suspended
within our proprietary urethane microsphere material,” say Callaway.

“Suspending the floating weight allows us to position the Center of Gravity deeper using a 3-piece iron construction. As a result we can create higher launch while allowing a thinner, faster Face Cup construction. That combination promotes distance-enhancing launch conditions that we’ve never been able to achieve before.”


Callaway Big Bertha Irons: Key Features

Energy Core
The Suspended Energy Core is the engine of the new Big Bertha irons. This revolutionary new construction suspends the MIM’d Tungsten weight using their proprietary urethane microspheres. It’s designed to deliver easy launch; long consistent distance; and incredible sound and feel.

Why we use a Foresight GC Quad launch monitor

Long, Consistent Distance From Our 360 Face Cup
Callaway’s 360 Face Cup employs a flexible rim around the face that flexes and releases at impact to increase ball speed. And by using the high launch angles generated by the Suspended Energy Core, they have created their thinnest face cup for increased speeds that promote longer distance.

Premium Design
Big Bertha has a clean Smoked PVD Finish, and is available with new Recoil ESX, Recoil ZT9, and KBS Max 90 shafts.
