About the Callaway Great Big Bertha Tungsten Titanium

The Great Big Bertha Tungsten Titanium irons of 1997 were Callaway's first titanium irons, pairing a large cast titanium head with a dense tungsten insert set low in the deep cavity to keep the centre of gravity down. The loft ladder matches the steel Big Bertha irons of the era — 33 degree 7-iron, 46.5 degree pitching wedge — with Callaway's typically upright 65 degree wedge lies. They were premium-priced clubs sold mainly with the RCH 96 graphite shaft, and were replaced by the Hawk Eye titanium irons.

Frequently asked questions

What is the loft of a Callaway Great Big Bertha Tungsten Titanium 7-iron?

The Great Big Bertha Tungsten Titanium 7-iron has a loft of 33 degrees, with a 62.5 degree lie and a published length of 37 inches.

When did the Callaway Great Big Bertha Tungsten Titanium irons come out?

They launched in 1997 as Callaway's first titanium irons and were replaced by the Hawk Eye Tungsten Injected Titanium irons.

Why do the Great Big Bertha irons combine tungsten and titanium?

Titanium is about half the weight of steel, so the head could be made much larger; the dense tungsten insert then concentrates mass low in the cavity to lower the centre of gravity and raise launch.

Finding a used set

The Callaway Great Big Bertha Tungsten Titanium ran from 1997 to 2000 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

Data compiled from:

qsponge.com / golfclubspec.com Callaway Big Bertha Tungsten Titanium iron spec table — loft, lie, length and steel/graphite swing weights for the full 1-LW range
2nd Swing Golf specification table for the Callaway Big Bertha Tungsten Titanium iron set (2ndswing.com) — corroborates every loft, lie and length figure, and lists the RCH 96 graphite stock shaft
The Sand Trap forum, 'The Legendary Callaway Great Big Bertha Tungsten Titanium Irons of 1997', and MyGolfSpy coverage — support the 1997 introduction year
Caution on lengths: both spec databases publish the same unusual ladder in which adjacent irons share a whole-inch length (2/3 at 39 inches, 4/5 at 38, and so on). No independent period catalog could be located to confirm or refute it, so the figures are recorded as published and confidence is held at medium. Steel swing weights are recorded (graphite ran two points lighter); offset and bounce were not published
