A topside buoy system is disclosed for relaying a status of a diver between a monitoring station and a diver's wearable device and scuba tank pod. The communication may be carried by sonar signals underwater and may be transmitted by short-range communication methods through air. An application on the command station may display diver status information and may receive and transmit messages between the command station and the wearable device of the diver via the topside buoy. The diver location data may be determined relative to the topside buoy by determining a time delay of the sonar signal between the wearable device and the topside buoy, by a plurality of transducers configured to detect an angle from which the sonar signal originated, and a depth of the diver included in the sonar signal.

A scuba tank pressure monitor system comprises a scuba tank pod and a wearable electronic device. The scuba tank pod includes an air pressure detector, a first transducer element, and a first processing element. The air pressure detector detects an internal air pressure of the scuba tank. The first transducer element transmits sonar waves including scuba tank related status data having a first frequency range. The first processing element controls the first transducer element to transmit sonar waves including the scuba tank related status data. The wearable electronic device includes a second transducer element, and a second processing element. The second transducer element receive sonar waves including the scuba tank related status data from the scuba tank pod and transmits sonar waves including alert tones having a second frequency range. The second processing element controls the second transducer element to transmit sonar waves including the alert tones.
