About the Callaway Big Bertha B21 Single Iron

The Callaway Big Bertha B21 Irons fall right in line with all the other Big Bertha irons produced all the way back to 1994, they go far and they are forgiving on mis-hits. The B21 model features "A.I.-Designed Flash Face Cup" technology. It employs artificial intelligence to create a clubface with variable thickness patterns optimized for each specific iron. The Flash Face Cup helps to maximize ball speed and increase the size of the sweet spot, providing consistent performance even on off-center hits. This technology enables the face to flex more efficiently at impact, enhancing energy transfer to the ball and promoting greater distance. Additionally, it helps to lower the center of gravity, which aids in achieving higher launch angles and improved trajectory control, making the B21 Single Iron more forgiving and effective.
