I have been on Red Sea LoBs in Egypt, Sudan and Saudi Arabia which included hammerhead dives. The dives were conducted the same off all the LoBs due to the normal behaviour of hammerheads in the Red Sea. The dive begins by heading out to deep, blue water approaching or exceeding the recreational dive limits. You hang still in the blue water and wait for the hammerheads to get curious and come up from the even deeper water. Sightings of hammerheads up close were not that common (sightings of them in the deep were common). Divers on air had a very short time at depth. Divers on nitrox (27-29%) would have to set their ppo2 to 1.6 to get to an appropriate depth but would get significantly more wait time for the hammerheads to come up.
The boats I used were in the Blue O Two, Explorer, and Aggressor fleets. I did use an independent boat in Saudi Arabia. The guest were primarily British, German, other German speakers, and Scandinavian. There were few Americans. Russians were prohibited on at least two of the boats unless they specifically agreed in advance to follow certain diving rules.
Better places to see hammerheads up close are Cocos Island, Galapagos, and Malpelo. None of them easy to get to and all more expensive than the Red Sea.
PADI, SSI, SDI, and TDI do not require actual dives for certification. The book portion of the class can be done on-line but you still must go in person to learn to analyze a tank and understand your computer settings.
