Abstract
In a sonar buoy suspended from a helicopter, the lower stabilizing ring of a buoy of this type is replaced by a set of fins which get folded against the body of the buoy during its descent into the water and get unfolded when they are raised again to form a stabilizing crown around the bottom of this body, thus enabling a buoy of this type to be stabilized both during descent and when being raised again.
