ABSTRACT:
An underwater communicator device (10) is disclosed which permits acoustic communication with another diver by use of a voice synthesizer (42) cooperating with an acoustic transducer (40). A display (34A) is also provided to visually communicate the message. The keyboard (18) of the device (10) permits the diver to communicate stored messages by activating a single key 54 or to enter a complete arbitrary message by keying in the actual message. In other forms, the device (10) can include an air pressure transducer (60) for monitoring air tank pressure with a warning of low pressure. A depth pressure transducer (64) can be incorporated into the device (10) to monitor the depth of the device and diver. A bottom timer can be incorporated within the device for measuring the time of the depth. These functions can be continuously displayed to the diver on display screen 34B. The microprocessor (46) within the device (10) can be provided with a mathematical representation of a dive table to calculate the decomposition needs of the diver based on the depth and bottom time measured.
