Abstract
Mask for underwater activity, characterised in that, on a portion of the mask lying in the field of vision of the diver, there are applied, at positions which do not interfere with normal vision, optical signal displays 2, 6, 7, 8, controlled by the microprocessor 9 of an electronic instrument such as a decompression gauge, said microprocessor 9 with corresponding sensors being contained in a housing associated with or made in the frame of the mask itself. Said optical displays are preferably of the LED or liquid crystal type. <IMAGE>
