This club features perimeter-weighting in a larger, longer clubhead, delivering a sizable sweet spot. Substantial weight placed toward the bottom of the club allows for a high launch angle and softer landings. Even more discretionary weight is created by Callaway's S2H2 technology that moves the mass usually placed in the hosel to other parts of the club.
Shaft / Composition
The Callaway Big Bertha graphite shaft that comes standard in this club is a low-torque, mid-kickpoint shaft that allows better players options when flighting their shots. Bore-through technology places the shaft all the way through the clubhead into the sole plate, giving the player more substantial feedback from the ball and each shot. The stiff flex version of this shaft is designed for players with a swing speed of more than 100 mph.
The Big Bertha 7-wood has 22 degrees of loft as the standard. This falls into the standard range industry-wide for fairway wood lofts. This helps get the ball into the air quickly and land softly. The other models vary in loft, from the 16-degree 3-wood to the 25-degree 9-wood.
The Big Bertha fairway wood was the latest in Callaway technology when it was introduced in 2007. Changes to the steel-headed club including a thinner face, thinner metals in the crown and sole plate and an even smaller hosel resulted in the availability of more discretionary weight in this club than ever before. Callaway designers took that weight and distributed it around the perimeter of the club inside the head to make this a particularly stable 7-wood with a high moment of inertia that keeps the club from twisting unnecessarily.
This club is no longer available new from the manufacturer, but it can be found through any number of pro shops and online distributors in remainder stock or through Callaway's pre-owned Web site.
