Abstract
Abstract A dive parameter transmitter/receiver assembly for scuba diving includes a transmitter circuit with a control unit with one or more sensors for detecting dive parameters and/or information to be displayed. A modulator is included for modulating the parameter(s) or information and a transmitting transducer for propagating the parameter(s) or information. A receiver circuit is included and has a receiver transducer, a demodulator, a decoder, and a display for displaying the parameter(s) or information.
