you might be hitting down on the ball the shaft needs to be weaker your loft needs to increase good luck

I second Ron's advice.

The biggest improvement I ever made in my game was seeking out a local PGA teaching professional. He watched me hit 1/2 a dozen balls and told me my clubs were too short and the shafts were too whippy. He made an appointment for me to see the club fitter over at Dana Rader golf school. The new clubs were so different I had to go back and take lessons to learn my golf swing all over again. It was worth it as my scores plummeted.

 

Good luck.
