Offset in the Club.

Offset in the club means the leading edge/club face is set behind from the hosel/shaft of the club.

It does two things.

1. Because the clubface is set behind the hosel, it gives the player a fraction more time to square the club at impact. Thus it helps to combat the fade and slice should the player not square the club at impact.

2. The CG of the club is set further back when the club is offset. Due to this, the trajectory of the ball is higher for the offset club, compared to a non-offset club with the same loft.

So it seems that its meant more for the Game Improvement club.

But if you are a better player you'll be able to use the offset and adapt to it.
