How to identify this generation
- Match both Big Bertha and the 2023 product page; the family name has been reused.
- A Big Bertha hybrid/iron combo is a separate composition; identify each head before using an iron row.
- The Big Bertha name also appears on these Callaway irons; compare their markings before using this chart: Big Bertha (2015); Big Bertha OS (2016); Big Bertha (2019).
What to notice in the specifications
- Its 7-iron is 2° stronger than the 2023 Paradym 7-iron.
- The 4-iron is 18° in this standard chart.
- The published set range does not mean every used set includes all four wedge rows.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
Read our loft guide for a worked example of comparing the numbers, and our used iron checklist before relying on a seller's description.
