They're now called DSD Leaders (as well as DiveMasters), as I mentioned in post #2 in this thread.PADI Divemasters in Active Status (and with insurance, where required) may conduct PADI Discover Scuba Diving programs in a pool or confined open water environment after successfully completing a Discover Scuba Diving internship. The internship consists of conducting four separate PADI Discover Scuba Diving programs in a pool or confined open water environment under the direct supervision of a PADI Instructor.
