Abstract
Abstract The present invention relates to a method and system for scanning a specified underwater area with sonar energy to generate sonar image signals of a submerged diver and othe objects within said underwater area, processing said sonar image signals at, for example, a remote station such as a surface vessel, whereby information is incorporated with said sonar image signals for designating a route from the starting underwater location of the diver to a particular underwater object, and transmitting said processed signals to an image monitor carried by the diver for providing him with visual directional information to assist him in going from his starting location to the location of the targeted object. Preferably, said directional information includes a route or heading line that the diver can follow on his monitor in moving toward the object.
