The AQUARIST is a hardwired half / full-duplex underwater communication system for conversations between the surface (public) and one divers.
This communication unit is specifically designed to meet the needs of underwater live event/presentation with public / audience and to connect to a mixer / PA system.
It makes it possible for a diver in a tank / pool (ie-aquarium) with an IDM to communicate with an outside audience (extending the capability of an integrated loudspeaker of a typical surface unit) and viceversa for the audience to communicate back to the diver.
