Dewi Nusantara uses a Nitrox Technologies membrane system to produce our diving gases. This method is very safe and accurate. We have several O2 analyzers on board for guest use and it is mandatory that divers analyze and log their personal dive cylinders with every new fill. Instruction is available on how to analyze and log a mix accurately.
Please be aware that you are responsible for your own dive profile at all times.
In recent years the use of rebreathers has become popular among sport divers. Dewi Nusantara will offer rebreather diving in the near future.
