Who hasn't been annoyed when the dive computer orders us to go "up" when the octopus is just leaving its cave or the huge school of barracudas is swimming around the drop-off? In the Maldives in particular, some interesting thilas (reefs) only start at 20 m and leave conventional compressed air divers little time to fully enjoy the dive. It is often necessary to surface at just under 100 bar because the no-decompression time is coming to an end. In the Red Sea, many top spots with sights of unparalleled beauty unfortunately only attract divers below the "eternal" no-decompression limits. Even "Mediterranean divers" know a thing or two about it, when the wreck lies so wonderfully in the light right now or the gorgonian fields stretch out almost endlessly in front of you, but the dream is abruptly interrupted by the beeping of the computer. To avoid all this, simply replace your compressed air cylinder with the appropriate nitrox mixture. The prerequisite for this is, of course, an internationally recognized nitrox specialty. With the EAN (Enriched Air Nitrox) Specialty Diver certification, you are authorized to dive internationally with up to 40% nitrox. In addition to the safety regulations and guidelines, the course also includes many practical parts, such as determining and measuring the nitrox content, filling out the nitrox book and marking the nitrox cylinder. ATTENTION: registration by telephone or in person is required.
