ABSTRACT:
Floating apparatus for the remote marking of the position of bodies that have fallen in water, comprises a buoyant body which is ballasted on its underside and which on its upper side carries an inflatable standard having a visible signal at its upper end. The inflatable standard is in the form of inner and outer tubes which define between them a hollow chamber that extends lengthwise of the standard and parallel to the standard. A supply of compressed gas, carried by the apparatus, is selectively releasable to fill the hollow chamber to erect the standard.
