Additional Information
Callaway Great Big Bertha Irons w/ Steel Shafts
This is the titanium iron reinvented--Callaway’s first ultra-premium multi-piece, titanium design. We are combining driver-like power with the precision of an iron. By combining our titanium face and body with up to 145g of tungsten, we’ve reached a new level of speed, forgiveness, and overall performance. This multi-material construction creates lightweight power for effortless distance and control.
Lightweight Power from a Forged Titanium Face and CP4 Titanium Body
By leveraging materials that are typically reserved for drivers, we’ve generated up to 96g of discretionary weight, and precisely repositioned this saved weight to increase launch and forgiveness. The Great Big Bertha iron features the thinnest titanium face we’ve ever used in an iron. On top of that, it’s also the lightest. The Commercially Pure Grade 4 (CP4) Titanium body flexes more at impact than traditional steel and works together with the thinner face to transfer more energy to the ball. We’re providing legendary driver performance in an iron.
Speed and Launch from the Tungsten Speed Cartridge
The Tungsten Speed Cartridge features up to 145g of high-density tungsten, which provides increased speed and launch by giving us the deepest center of gravity we’ve ever achieved in an iron. This unmatched level of tungsten is a 133% increase over Rogue ST Max, and the most ever in a Callaway iron.A.I.-Designed Forged Titanium Face for Increased Consistency
The forged titanium face is optimized to increase speed and improve spin consistency. Great Big Bertha is the first Callaway iron to combine titanium and industry-leading A.I. technologies for optimized performance.Patented Urethane Microspheres for Exceptional Feel
Our patented urethane microspheres enhance sound and deliver a softer feel, while still allowing the face to flex for more ball speed.Great Big Bertha Graphite Irons Specification
