Abstract : The patent relates to a hydrophone stabilizing device in which the hydrophone is maintained in neutral buoyancy and in a stabilized attitude during low speed tow and while tethered. The hydrophone is suspended about the center of buoyancy of a major flotation member and is maintained in a stabilized attitude by the linkage of supporting arms which are selectively pivotable in the plane of the tow line. A smaller float is positioned at the intersection of the immediate vertical supporting arm and an intermediate arm or boom connecting the supporting arm to a vertical strut to assure that the point of intersection of the arms is always above the hydrophone.
