Vous, plongeurs, souhaitez optimiser votre SÉCURITÉ, augmenter votre temps de plongée, avoir moins de temps d’intervalle de surface et conserver toute votre  énergie après les plongées, APPRENEZ à plonger Nitrox.

Pour être inscrit à ce programme, vous devez être un plongeur Open Water Diver au minimum. La certification Nitrox vous permettra de plonger Nitrox n’importe où dans le monde. Nous enseignons ce cours gratuitement. Il suffit de payer les frais de SSI (Scuba School Internatiional).

Plonger avec une bouteille Nitrox signifie que vous avez plus d’oxygene que normal et donc moins d’azote. Selon le plan de plongée prévu, vous pourrez alors théoriquement plonger 2 fois plus longtemps et avec moins de risque d’accident de décompression car vous accumulerez moins d’azote dans votre corps durant la plongée.

Exemple pratique: 

Si vous plongez en Air à 27 mètres, votre temps de fond maximum sera: 30 min VS Si vous plongez en Nitrox 38 à 27 mètres, votre temps de fond max sera: 50 min

PS: Air = 21% d’oxygène & Nitrox 38 = 38% d’oxygene

Pre requisites

What does Nitrox / Eanx means?

Nitrox is a breathing gas enriched with Oxygen. With a nitrox compressor, we can prepare blend of air with different pourcentage of oxygen (up to 40% for recreational diving comparing with the 21% that you are used to breathe at 1 bar).

Hence, diving with a nitrox blend will allow you accumulating less nitrogen due to the fact that you will breathe more oxygen. As a result, you have the option to dive longer with your computer set on nitrox.

You will increase your safety in reducing the risk of decompression sickness if you dive with your computer set on air. In other words, you will be ready to go diving on liveaboards for instance.
