The Callaway Big Bertha 7 iron (commonly from the early 2000s Big Bertha iron sets) is a game-improvement short iron designed to make golf easier through high forgiveness, strong launch, and consistent distance control. Built with a deep cavity-back design and perimeter weighting, it helps stabilise the clubface on off-centre strikes, producing straighter shots and more reliable carry distances than traditional blade-style irons. Only one available – ready to ship from Australia.
