The Launch Angle should be more than the Loft of a Driver

To hit it longer with a driver, your launch angle should be more than the loft on your driver.

 

To get the maximum distance off the tee, you need to increase your laucn angle and reduce backspin on the ball.

 

The important key is to have right combination. Higher launch angle with lots of backspin or too little backspin won't help you hit the ball far.

 

You will certainly lose distance if you hit it before the lowest point of your swing arc.

 

 To increase launch angle, you need to hit the ball on the lowest point or just after the lowest point of your swing.

 

So you need to sweep the ball off the tee or hit it slightly on the upswing.

 

Players often slice trying to hit it on the upswing. To avoid open face at impact, you should make sure your right shoulder is lower that your left.

 

If your right shoulder is too high at address, you need to drop your right shoulder through impact to hit it on the upswing.

 

This will cause you to open your clubface.

 

If your right shoulder is lower at address, you don't have to drop it down at impact.
