The latest tool that enables divers to extend their time underwater is the use of breathing mixtures. One of them is NITROX (also known as ENRICHED AIR, SAFE AIR, etc).

The development of diving is mainly associated with our desire to stay underwater longer. Diving suits are warmer and more comfortable, and cylinders contain more air.  An increasingly important limit is decompression or, more precisely, no decompression limits. A dive computer which monitors the actual dive profile and calculates the optimal decompression has become a normal part of the equipment. Nevertheless, we are still not satisfied! We want to stay underwater longer and experience less decompression.

The latest tool that enables divers to extend their time underwater is the use of breathing mixtures. One of them is NITROX (also known as ENRICHED AIR, SAFE AIR, etc).

NITROX is a mixture of nitrogen and oxygen, which contains more oxygen than normal air – usually between 21 % and 50 %.  Since NITROX enables the body to absorb less nitrogen, we can stay underwater longer and without decompression. It offers the most benefits at depths ranging from 15 m to 30 m, especially if the terrain enables multi-level dives (e.g. sunken ships). It can be also used at a depth of approximately 50 metres, and for better decompression during technical decompression diving. The market now also offers NITROX dive computers that combine the advantages of multi-level diving and NITROX.
