How to adjust your Callaway Epic driver

The Callaway Big Bertha Epic driver has an eye-catching triaxial carbon crown and Jailbreak Technology for colossal distance and is one of the best adjustable drivers on the market. With the potential to change the loft, lie, and influence draws and fades, our guide breaks everything down to get your Epic driver set up for your game.


Both the shaft and adjustable weight screw are loosened and tightened with the wrench you'll have received with your driver. To open or loosen either screw, place the wrench into the top of the screw and turn anti-clockwise. To tighten the screw, turn it clockwise. When fully tightened, there will be an audible "CLICK" to let you know the sleeve is safely locked in place and to avoid over-tightening.

Before opening the sleeve screw on your driver, take a look at the markings on the hosel. There will be a pair of hyphens which work as a guide when lining up your desired settings.

When fully opened, the head can be detached from the shaft. You'll notice the top and bottom cogs can turn independently of each other and these indicate some of the different loft and lie options you can choose. You can add up to 2 degrees of loft or go 1 degree lower. Then for each loft, you can choose a neutral and a draw. The plus and minus are pretty self-explanatory; however, the letters can be confusing. The 'S' is for stated or standard loft, and the 'N' is for netural, and 'D' for draw.

The two cogs work together to form a little 2-piece jigsaw, only fitting together in one of the possible combinations. Just spin them around until you find the right one for you - whether it's plus one with a draw (+1, D), minus one and neutral (-1, N), or any other setting.

As well as the hosel adjustability in the Epic driver, you also have a huge 17-gram sliding weight. Loosen this weight with the wrench and move it to any position along the rail.

Sliding the weight towards the heel will promote a draw bias on your drives. If you struggle with a fade or want to correct a slice, this setting will help you. The opposite happens if you slide the weight towards the toe. This will aide a fade, so if your poor drive tends to hook, try this setting to correct it. Of course, you can secure the weight anywhere along the track to make the changes more gradual or more subtly.

It's important to remember - you can adjust your driver on the range or at any time before or after your round, just not during it!
