Abstract
Diver communication equipment comprises a diver's helmet having a display consisting of a monitor, a prism, a relay lens and an eyepiece. The relay lens and the eyepiece are mounted in a tube which extends into the helmet through a sealing bush located in place by a nut. The helmet also caries a television camera and a light. By looking up at the eyepiece, the diver can see, through one eye, video images from the monitor derived from the camera or from another camera located topside of some other graphical or numeric information derived either from other devices subsea or other sources located topside. In a modification, the monitor occupies the tube.
