ABSTRACT:
The present invention relates to a method and system for generating signals which represent a map that depicts one or more submerged objects within an underwater area; detecting acoustic energy emitted from means carried by a diver within said underwater area, or scanning said area with sonar energy, to develop signals which indicate the location of said diver within said area; and combining said diver location signals with said map representing signals for producing a composite visual display to said diver which shows his location with respect to the location of one or more submerged map objects within said area. A remote station also may be provided at which several of these functions are performed.
