Rebreather / Nitrox
There are big advantages using rebreathers (breathing apparatus):
- Longer diving times possible
- No outgoing air, thus, the animals under water do not get disturbed and a more intense experience of nature is possible
- The devices are very quiet, there is no disturbing noise (blubbering)
- Comfortably humid breathable air
During Nitrox diving, there is oxygen being added to the breathable air. Advantage: longer and deeper dives with less decostops. Diving with Nitrox requires a high grad of discipline and knowledge.
