The present invention relates to a decompression buoy (1) comprising an inflatable bag (2) having a tubular portion (4) defining a an inside volume (12) and a longitudinal opening portion (6) with a first end (14) leading to the inside volume (12) and a second end (16) leading to the outside. The opening portion (6) thus enables gas to flow between the outside and the inside volume (12). The opening portion (6) includes a throat (18) of transverse dimension that is smaller than the transverse dimension of the first end (14), and the second end (16) is adapted to receive the end of a diving regulator.

A dive mask including an ultrasonic communication system and an alert subsystem to measure the distance between two dive masks and alert divers if they have moved apart and exceeded a setpoint range. An illuminating edge or indicator light including at least one LED will illuminate to notify the divers they have moved apart and exceeded the setpoint range. The dive mask includes a danger function the divers may trigger to notify each other of potential danger. The dive mask includes a function to illuminate the at least one LED if the battery level in either dive mask is low.
