"SV-1200" Underwater Communication System that Allows Communication among Up to Four Divers

UETAX is exhibiting their ""SV-220"" and ""SV-1200"" underwater communication systems.
　This equipment makes it possible to have communication between engineering divers that are underwater with their boat on the surface, and communication among divers. Microphones and speaker are installed inside of the diver's full face mask so that it is possible to speak using the hand mic of the amp box above ground. Similarly, communication is possible between divers.
　With the SV-220, communication is possible for up to two divers, and with SV-1200, communication is possible for up to four divers.
