This is a multi-stopper that can be combined with a drop sinker to change the mode to various rigs without changing the knot. 
By choosing a size that just barely passes through the eye of the drop sinker you are using, you can move the sinker back and forth at the intended timing while taking advantage of the sinker stopper function.
It can be quickly transformed into a free rig, zero-dung style, or caro rig.
It is especially useful on the bank where you cannot carry many rods.
Of course, it can also be used as a Texas rig stopper.
