Hi all. My name is Achille costa-Lantin, working for a French aircraft manufacturer in Saudi Arabia (Technical assistance). I'am a PADI rescue diver and me and my friend, we enjoy the diving in the red sea Djedha, Al Farasan Islands, etc. The only problem, the monitoring of our movement by the coast guard and the police and also the return in our compound at an altitude of about 2500 meters. The use of the NITROX is almost mandatory here. Anyway, we have fun
