Abstract

The gauge comprises a case (10) having a face (11) bearing reference marks disposed over an arc of a circle centred on the axis of rotation of a hand (12). A first zone of the face consists of sectors (33), (34) over which the hand moves according to the depth of the diver. Between the sectors (33) (34) is a sector (35) forming the second zone of the face, in which the hand moves whilst measuring time during the diver's ascent. This sector 40 corresponding to the three metre stage is covered in the direction of the arrow A in thirty minutes when the diver ascends. A number of the zones may be provided to indicate the required decompression period at several depths. <IMAGE>
