The 20 coil is designed to allow you to distinguish where the target is located by producing a single tone if under the front of the coil, and a double tone if under the back of the coil. To pinpoint, simply pull the pinpoint trigger as you would with any coil, and the back half of the coil will null, allowing you to use only the front half of the coil to pinpoint your target.
A 20 coil has the scanning height of TWO stock coils! That is insane. Great for picking up shallower coins and maybe jewelry (but I'm not sure if the 22.5kHz will work well). Also, the double beep and pinpointing feature is interesting...
