Hi,  Here is an explanation of rhe SureFit system and what it was designed to do.

Our SureFit Tour hosel system mechanically adjusts loft and lie angle, not face angle.  A change in face angle comes from the fact that when you change loft angle, you also change the ground contact point on the sole.  When you add loft, the ground contact point shifts back and when the driver is soled, the face angle closes (please note, the face angle only changes if you sole the driver).  The opposite happens when you decrease loft.  The ground contact point moves forward and the face opens.

Now for the chart.  We include a note that says Loft = Effective Loft with a square face at impact.  Most golfers try to point the face of the driver down their intended line, or said another way, square the face at impact.  So, if you start with a closed face angle and square the face at impact you are in fact adding loft.  Lets walk through how that happens.  If you change our SureFit Tour hosel setting to A4 you mechanically add 1.5 degrees of loft to our driver.  If you sole the driver, the face can close because of the ground contact point.  Most players then take the face and square it, thus adding the 1.5 degrees of loft.

If you change the setting and do not square the face, and you end up gripping the club and hitting your shot with a closed face angle, then yes, you hit it low left.  The key to our chart is squaring the face at impact.

The lie and loft changes are independent of one another, which means that you can change the lie without affecting the loft.  On the chart, if you go left or right, you are changing the lie angle without affecting the loft setting on that row.  So if you move the setting to A2, which is on the standard loft row, you are at standard loft and have made the lie angle 1.5° more upright. 

Hope that helps!

hi cathy, interesting answer, i have a question about that answer... i had a 913 d2 driver  9.5 set on A1 and never had a problem getting the ball up in the air, i now have a 915 D2 driver 9.5 and now i can't get the ball to get up in the air it is currently set on A4 can you advise on what setting I should try? I have a in to out path and i am snap hooking it low 

thank you

Put the ball at your front foot and swing out. If you need to, slow your swing down to add more control. Most of all take your time at the range and really focus there. 

The first question would be did you try the same shaft that was in your 913 in your 915?  or did you change shaft as well as flex?

In the 913 i had the blue diamana 62g in s

in the 915 i have the blue diamana 60g in s

A great deal of detail but very well said.

Now for fairways and hybrids, how does that affect turf interaction. Because the sole of the club is not oriented the same as it would be at the A1 position.
