Benjamin Rayner, 38, who had moved to Lossiemouth in Moray from Cheshire, was named by Police Scotland yesterday, five days after Sunday's accident.
Mr Rayner, a qualified British Sub Aqua Club [BSAC] diver, got into difficulties during a dive with colleagues at Findochty, Moray.
Coastguard crews, an RNLI lifeboat, a search and rescue helicopter and an ambulance were all involved in the rescue effort.
His parents Richard and Janet Rayner said: "We're absolutely devastated by Ben's sudden and early death. He was a lovely man with a great sense of humour.
"Ben was very close to his family and very loyal to his friends. Although he moved from Cheshire to Scotland primarily to work, he enjoyed living in Lossiemouth. He loved diving and was proud to have gained his BSAC qualification. Ben will be sorely missed by all who knew and loved him."
