Big Bertha Fusion

Big Bertha Fusion pushes the boundaries of forgiveness like no Callaway club ever has. The key benefit? More forgiveness means straighter flight on mis-hits, and straight flight nets longer distance, drive after drive.

To increase forgiveness you have to raise the head’s MOI measurement. We’ve succeeded dramatically by developing a revolutionary clubhead design that starts with an aerospace-grade titanium exoskeleton called an Exo-Cage™. The Exo-Cage is fitted with a crown and sole composed of an ultra-light, ultra-strong material called triaxial carbon. Triaxial carbon is made possible by the deep knowledge we’ve gained from our years of experience incorporating carbon materials into our metalwoods.

Big Bertha Fusion’s numbers speak volumes. The revolutionary new triaxial carbon material is over 65% lighter* than titanium, and more than 35% thinner than our previous forged composite material. This allows us to position a remarkable 35.4 grams** in strategic areas of the head to optimize the center of gravity and increase the MOI by up to 17%*** — a remarkable jump that golfers will notice by increasing the quality and accuracy of their off-center hits.

This driver also incorporates Callaway’s Speed Step technology, devised with the help of aerospace experts, to enhance the head aerodynamics, promoting faster clubhead speeds.

Big Bertha Fusion comes stock in both a 45.5” length for exceptional distance or a 44.5” length for enhanced control. All stock configurations are available with UST’s new Recoil driver shaft that’s designed to load more efficiently on the downswing and unload with greater power and precision through impact.

    Long & Straight!
    I usually wait a year or two to buy the "hottest" driver until the price comes way down. You still get a brand new club for half the price. This one was worth the wait. Love it.
    Prosgood look & good feel.

    This driver is awesome. Hugely forgiving and I’m finding way more fairways. Highly recommended for all level handicappers. Great experience at RockBottom as well.

    Awesome shape and sound.
    I have not been able to use this on a course yet because of the time of year and western Pennsylvania weather. I live on a farm so was able to hit a dozen balls in a field. Driver seemed solid.

    Hit it good the first time out but going to adjust to lower the loft. I had to tee the ball lower but that is OK because I was always laughed at because I always teed the ball high
    ProsLight, easy to swing and good distance.
    ConsCheesy head cover. I expect better of Callaway.

    Callaway Big Bertha Fusion
    Nice. Replaced my five-year old Big Bertha with this beauty... amazingly straight and long. I LOVE this club. Went from all over the property to where I want it to go. When the pros/ads tell you five years is the max on an older driver... believe them. The technology moves ahead fast, and when you hit a million balls with your old driver, it just plays old.
    ProsLove the look, feel, accuracy, and distance of this club. Equally love the adjustable loft and fade/draw option... glad they kept that. Interesting pop off the club sounds a bit like the Cobra clubs, but not as loud, and not a muted sound like my old Bertha.
    ConsNot a big fan of the throw-back head cover, and others seem to agree that the shift back and away from the sock-bottom cover wasn't a positive move. Maybe done for durability. Hey, it's just a cover.

    Best Driver
    This is by far the easiest to hit driver I have ever owned. I have not changed any settings as of yet. With the base settings I can work the ball either way.
    ProsLightweight, neutral look
    ConsI haven?t found any yet.

    Great club for the price. When you hit the sweet spot, you cant even feel the ball leave. Still new to me so i need to adjust for the new club a bit but so far it has added about 30 yards to my drives!!!
