A golf player can move the course of the game with the right equipment. But choosing which set of clubs to get requires a lot of consideration. With countless options in the market, buyers are often overwhelmed which to choose.

To avoid purchase regrets, we’re here to discuss an excellent option – the Callaway Big  B21 Bertha Irons. If you want to know if it’s the right club set for you, here is our detailed review:

Big Bertha B21 Irons: The Overview

Big Bertha B21 Irons has proved to be a giant leap for the brand as these clubs are designed using AI.

Callaway engineered these for players who desire confidence, higher ball speed, lofty launch, and better straight shots. They have improved the ball speed, mainly due to the new Flash Face Cup with artificial intelligence (AI).

The AI helps in improving robustness in a spin. The AI coupled with the Flash Face Cup enables flexibility in the face which enables it to cover more yards. They offer great forgiveness, sound, and feel, and are liked by high handicappers. Therefore, they are considered one of the super game improvement clubs. 

Treat for High Handicappers: Big Bertha B21 Irons

According to Callaway, the Big Bertha B21 Irons are made for golf players who have lost speed and distance due to age or medical conditions, as well as returnee players. The loss of speed and distance experienced by returnee golf players and senior players urged Callaway to design and engineer the Irons. 

Callaway branded this customized product with the tagline of ‘Distance any way you swing it.’ Indeed, these offered long-distance, straight shots, and high ball speed. 

Forgiveness Like Never Before

The Callaway Big Bertha B21 Irons is a product of Callaway’s high-tech engineering and artificial intelligence. However, the design is also influenced by the earlier versions. Since the designs of previous versions offered high forgiveness, the Bertha B21 Irons wasn’t left behind.

In long Big Bertha Irons, the ball speed is managed with the cup face and artificial intelligence. The cup face allows us to compensate for the ball’s missed location on the iron’s face during the hit.

In short Bertha Irons, the spin and launch consistency is managed through the cup face and artificial intelligence. Since the long and short Big Bertha Irons manages the speed, spin, and launch consistency, they offer greater forgiveness from the club’s category.

Sound and Feel Like You Never Had

The sound produced from the Bertha B21 club hit is managed by the padding behind the club’s face with urethane microsphere material. This way, the sound and vibration are dampened.

Weight of the Big Bertha B21 Irons

The engineers and designers at Callaway have smartly managed the weight of the Bertha B21 irons. The head of the Bertha B21 iron weighs up to 40 grams. The head is mostly made up of tungsten material (tungsten weighting). The tungsten weight is divided into two areas, the toe and face weight. 

The toe weight helps in managing the center of gravity. By managing the center of gravity, the clubhead speed is improved, among others. 

The tungsten weight is also divided onto the face, known as the face weight. The face weight drags the center of gravity downwards. This way, the dynamic loft is added whenever a ball is hit. The other way to add loft is through adding gadgets, which in the case of Big Bertha B21 are not required.
