The 25-year-old man was reported missing yesterday about 3.15pm after he failed to return from free diving around Titi Island.
Search and Rescue teams, the Coastguard and a helicopter searched for the man and other private vessels joined in.
Senior Sergeant Peter Payne said the dive squad was now searching near the island where he was last seen.
