First of all, get a sand wedge with at least 10 degrees of bounce. I use a 58 degree, with 12 degrees of bounce. This helps the player get out of any bunker with ease and accuracy. Secondly, open the clubface a few degrees to increase loft, then place your hands on the club, open your stance and hit just behind the ball to build up sand on the clubface. make sure you swing through the shot with an accelerating tempo.
