Firstly, it is tragic to hear the loss of a diver. What is equally distressing is the idea that they may never be recovered. I was wondering if it is possible to have a time/pressure released signalling device that divers should be made to carry. In case of a lost diver who does not surface, the device should trigger itself, shoot up the the surface and signal the location. Does such a gizmo make sense? Has something of the kind ever been developed?
