The problem with the snap hook are two things. First is that the golf ball curves out of control. Second reason that it will cause a lot of time searching in the woods.
The cause is that the golf club has a face angle pointing to the left at impact.
Closed face angle for right hand player.
The problem is to make your club be more pointing to the target through impact.
However there are many ways the club can be altered into a more square position. The most common way and dumbest is to grip the club more open at address.
The second most common fix is to rotate your left hand on your grip more counter clockwise and also your right hand. Test it out! If it does not work. Email me your swing.
