Abstract

The invention concerns a device comprising an acoustic source (1) located on the support boat (2) whereof the acoustic pulse transmissions (12) are synchronised by a time base (9). Each diver bears a battery-powered (10) receiver and signalling set (3), including a time base (4), at least three non-aligned acoustic sensors (5), electronics unit conditioning and digitising (6) the received acoustic signals and a processor (7). For each acoustic pulse (12) transmitted by the acoustic source (1), the diver's direction and distance relative to the boat are calculated purely passively by the processor (7) which displays them on the signalling means (8) of the receiver and signalling set (3). The device can distinguish among several groups of divers. It can receive alarm messages and perform the functions of a diving computer.
