Perfect for use in small water gardens or pond areas where you want a little fog but the water is too deep.

Buoy's Specs:

6-1/4" in diameter, 2-5/8" deep
Well opening is: 2-3/4" diameter

You can attach a small rope/cord to the base and then a heavy object to keep the buoy from floating around. This would keep it in one place.

NOTE!  You do NOT need this unit in order to operate a single disk fogger, this is for open water areas where the water is too deep for normal use.
