The last few years, a new symbol has flourished in many clubs / diving bases / dive boats: NITROX. This is a real improvement for diving. By increasing the% oxygen in compressed air diving cylinders, it increases the duration of the dives.
These advantages take on their full significance in the Seychelles, because the water temperature (between 27 and 30°C!!!) allows successive dives. You can do up to 4 dives a day, with one-hour surface intervals during which you can chill on the upper deck of the Explorer I or rest in your cabin.
This specialty is highly demanded because it allows you to dive with enriched air when it is available. Most of the training is based on techniques related to diving with NITROX: equipment, the risk of exposure to oxygen, the setting of your dive computer, the verification procedures of your bottle, etc..
Although most of the dives may be conducted in the area of 18 meters, it may be interesting, even exhilarating, to go further (wrecks,, fauna, flora, etc..). But new safety rules apply and require a technical approach, supervised by an instructor.
You will dive in between 18 and 30 meters, without exceeding 40 meters. These dives require no decompression stop, only the safety stop (3 minutes at 5 meters) is recommended.
We will explained you the effects of pressure and the phenomenon of narcosis. These factors specific to deep diving requires a strong background in risk management, decompression procedures and equipment.
