Callaway Big Bertha Iron Review - Technical Editor Joel Tadman tests out Callaway's latest distance iron for 2019, the new Big Bertha

Callaway Big Bertha Iron Review

This model is aimed at golfers seeking extra distance from their iron shots.

Key technology Faster ball speed and easier launch comes from the Suspended Energy Core, which comprises a floating tungsten weight suspended within Callaway’s urethane microspheres deep within the head. A thinner and faster 360 Face Cup – a shallow, flexible rim around the perimeter of the face – combines with the high launch from the Suspended Energy Core to deliver longer ball flights.

Our technical editor Joel Tadman tests out the new irons on the range.

How we tested We hit the 7-iron from the set on the launch monitor and then also on the range at West Hill to assess ball flight as well as true feel and sound.

Looks The smoked PVD finish creates a premium, anti-glare look. There’s a fair amount of offset but the top-line appears relatively thin for a distance iron. It sets up very inviting to hit behind the ball with the bottom white grooves assisting with alignment.

Performance This iron produces very fast ball speeds and very low spin, which contributes to extreme carry distances but still on a relatively high ball flight.

Everything about the Big Bertha iron has been designed for distance. At 26°, the 6-iron loft is strong, although it is the same as the Rogue iron. Yet, we got 3mph more ball speed and ten yards more carry distance on average with Big Bertha. Admittedly, the KBS Max shaft is 0.25 inches longer and the swing weight a touch lighter, but this also helps flight the ball higher.

The feel off the face is incredibly hot and very solid, almost metalwood like, and even poor strikes achieve good yardage. The very low spin won’t be beneficial for everyone; Rogue seems to be more playable for a wider spectrum of golfers and a little more affordable.
