Over the Wall, Small Hope Bay, Andros: 185 ft.
About 30 years ago.
Since, about 150 off Little Cayman wall, and 135 to bottom at Keys shipwreck reefs.
The Andros deep wall dive was to a niche in a sheer wall at Tongue of the Ocean. Bottom was nowhere in sight.
It was pretty tightly controlled even then. You could only do it after a series of dives, including one at same spot to about 120, and then it wasn't announced. They tapped you on shoulder and asked, 'Want to go?')
After we came up, somebody asked the divemaster, "How many times have you done this dive?"
DM: "I do it once or twice a week, so it's a lot."
Diver: "So what's the deepest you've ever gone?"
DM: "185 feet."
Diver: "You never went deeper?"
DM: "No. Why would I?"
