The CITA guideline is:
The recommended maximum depth limit with recreational scuba customers is 100 feet/30 meters, if
within certification (See Appendix ‘B’). The maximum depth with recreational scuba customers is
130 feet/39 meters and 100 feet/39 meters for repetitive dives the same day.
But Reef Divers (Cayman Brac and Little Cayman) has a diver waiver yo must sign that says:
I agree to abide by the recreational no-deco dive profiles and stay at or above the recreational depth limit of 110’ for computer divers and 100’ for table divers as set by Reef Divers. I understand that no decompression diving is allowed/permitted unless specifically authorized for technical diving by Reef Divers.
