You can see all the wacky records.
Tom Seitas holds the recognized record at 8'58" and 9'25" in competition
There is a guy, Robert Foster from USA, 590315 in San Rafael, California
Who stayed under 10 ft of water in a swimming pool. He hyperventilated with oxygen for 30 min before his descent and took his last breath at the bottom.
Stuff like that is not recognized as official.
When attempting records an AIDA official must be in the diver's presence for the 60 minutes before the attempt to insure there is no pure O2 or anything else done to enhance the dive.
