Each Callaway Big Bertha Steelhead clubhead is precisely balanced with a variable steel weight chip that weighs from 2 grams to 24 grams. This allows more weight to be placed deep in the club's sole, producing a low center of gravity allowing you to get the ball airborne with greater ease! This Big Bertha Steelhead also features the Hawk Eye sole plate, which is proven to make wood shots from any lie easier to hit! This is sure to bring greater confidence to your game!
