How to identify this generation
- BIG BERTHA lettering runs down a dark toe panel with red accents, beside a Callaway chevron badge in the cavity.
- Callaway reuses family names across years (Apex, Big Bertha, Rogue, X Forged), so match the year-specific markings and photo as well as the lofts.
What to notice in the specifications
- Callaway’s live site no longer serves this data to automated requests; the figures come from an Internet Archive capture of Callaway’s US specification panel dated 2016-08-14.
- Callaway also lists a women’s build (36.25 in 7-iron) with the same lofts and lies.
