An offset driver can be regarded as either a tool to improve your game or a crutch that keeps you from improving your game. If you fade or slice the ball, an offset driver might help you keep it in the fairways. A more extreme measure is to combine an offset with a turned-in clubface, called a draw clubface. This is a mechanical solution for someone who hates his customary slice, doesn't want to change his swing and seeks a quick fix.
An offset driver moves the head of the driver a little bit to the rear of the club, up to 5 mm behind the shaft. In theory, moving the clubhead back behind the shaft gives you more time to square up the clubface at impact, which will reduce a tendency to slice. Game-improvement and super game-improvement clubs, made for golfers with higher handicaps, often are offset. Some clubs are offset progressively. The driver and the clubs for longer distances are offset the most, while the short irons and wedges have little or no offset. Clubs for better players rarely are offset.
Many golfers, especially higher handicappers and beginners, are bedeviled by a slice that curves sharply to the right and winds up in the rough. Many swing flaws can cause a slice, but all of them lead to the same position at impact: a clubface that is open or moving at an angle that imparts sidespin to the ball. As Golf Club Revue explains, an offset driver gives you a better chance to square up your hands at impact by allowing you a bit more time to do so. Without the offset, your clubface would be even more open at the moment of impact, magnifying your slice. If your slice isn't severe, an offset driver might help you to hit fairways off the tee.
If you get rid of your slice with an offset driver, your shots are bound to be longer. All of the sideways distance from slicing will be straightened out and add to your length off the tee. You are likely to hit the ball higher and get it into the air more easily with an offset, since it helps square up your clubface at impact, imparting backspin instead of sidespin to launch the ball into the air.
Keep Your Old Swing
If an offset works for you, there's no reason to change your swing. You can keep the swing you're comfortable with and watch your tees shots go straight down the fairway instead of diving to the right into trouble. Club manufacturers also make offset drivers with a hook face that angles inward to accentuate the offset. You might even hit a draw off the tee instead of a slice or fade.
If you are a golfer with a bad slice, an offset driver, even with a hook face, might not be enough to stop your shots from veering to the right. You might opt to fix your swing instead of changing your clubs. Some lessons from a golf professional could be cheaper and more effective than buying offset clubs, and you could wind up with a much sounder golf swing that will enhance your enjoyment of the game.
