When do you use the approach wedge?
An approach wedge is simply another name given to a gap wedge,
it usually has either 50 or 52 degrees of loft. It fills the gap
between your sandwedge and your pitching wedge, you would use it if
you are too far away to use your sandwedge, and too close to use
your pitching wedge. You can use it for pitching, chipping and long
bunker shots. As the approach wedge has a mid-wedge loft spin rates
are rather high.
