Some images of the new Callaway Big Bertha irons, which come with 360 face cup technology for explosive distance

Callaway has unveiled it's new Big Bertha irons, which are designed to offer explosive distance to players of all abilities.

This is achieved through pioneering 360 face cup technology - the first time a face cup, previously used on fairways and hybrids, has been employed in an iron.

The new innovation on the Big Bertha irons has enabled Callaway engineers to create a thinner, and more explosive face.

The hollow-body construction has been combined with variable face thickness to create higher ball speeds all over the face.

Callaway says these developments means its new range of irons is two clubs longer than previous models.

Big Bertha irons have a two-piece construction, with both components forged from 17-4 stainless steel.

A new treatment process has also been utilised to improve the strength of the face - a much-needed development given it's now thinner and more flexible.

The centre of gravity is low and forward, facilitating maximum ball speed and a high moment of inertia.

Callaway has also intoroduced a new Big Bertha hybrid
