Useful diving specialties. There are a number of specialty courses. The condition is the completion of the basic course OWD (PADI, license to diving at max depths of 18 meters) or P1 (CMAS). Discussion on the quality of training of both the federation is as old as the world, but specializations in both are very similar.
Which specialties are most important for traveling divers? Subjectively, I suggest select several of them.
NITROX-that is, the licence to diving with oxygen enriched mixtures. In recreational diving nitrox used 32 and 36 - that is the percentage of oxygen (normal air 21%). The diver breathing a mixture of nitrogen saturation is lower and longer timeouts without decompression diving.
In some countries, you have to have a fear signal, in the case of a group, while diving in currents and in waters where the vessel is flying a lot. Expertise is afraid of learning support SMB diver.
Diving Night (Night Diver) does not require comment-is one of the most exciting dives. This course teaches safe diving at night, hardware configuration and illuminated signs, and protect diving in the dark. Control of buoyancy (Peak Performance Buoyance) is a skill necessary for safety in diving and underwater photography. Without the licence to wreck diving in many countries will not be able to see interesting wrecks. Similarly, diving deep.
The course develops the ability to dry suit and buoyancy control lets dive into the cold waters throughout the season. First aid and emergency first response(EFR) teaches rescue and help in many situations. Skills described above make you a safer diver and partner-important for the group.Stephon Tuitt Womens Jersey
