A diving apparatus includes a support structure ( 18 ) that is engageable with a diver's head, the support structure ( 18 ) defining a lens opening ( 262 ) and an equalization opening ( 104 ). A lens ( 26 ) is mounted on the support structure ( 18 ) to close the lens opening ( 262 ) so that the support structure ( 18 ) and the lens ( 26 ) define a breathing space ( 30 ) from which the diver can be supplied with air. A sealing arrangement is positioned on the support structure ( 18 ) sealingly to engage the diver's face so that the breathing space ( 30 ) is substantially airtight. An equalization assembly ( 106 ) is mounted on the support structure ( 18 ) to close the equalization opening ( 104 ). The equalization assembly ( 106 ) includes an access means to permit the diver to gain access to his or her nose so that the diver can carry out an equalization procedure. A gas supply arrangement is in fluid communication with the breathing space ( 30 ).
