A bi-directional underwater communication system provides a submerged operator with the capability to communicate with a surface site. A face-mask-mounted microphone and an earphone are connected to a submerged, watertight radio. The radio antenna cable is carried by a buoy to the surface of the body of water in which the operator is submerged.

A system for bi-directional radio communication between a diver and a remote location comprising: a separate watertight radio transceiver; watertight microphone means operatively connected to the transceiver for transmitting and receiving voice communication; a face mask for the diver; the watertight microphone means including a separate earphone worn in the ear of the diver and a separate mouth piece mounted in the facemask; buoyant antenna means operatively connected by a cable to the transceiver for floating at the surface of a body of water; said buoyant antenna means including a buoy having top and bottom ends and an antenna which is mounted on the top of the buoy for extending upwardly therefrom above the water; and reel means interconnected in the cable between the transceiver and the buoyant antenna means in proximity to the diver for reeling and unreeling the cable so that the antenna can remain above the surface of the water while the transceiver is submerged at various depths.
