1 Star Nitrox Diver

certified with ISO 24801-2, equivalent to:

- CMAS 1 Star Diver

- RSTC Open Water Diver.


Once you do the theory and practices in pool and sea and pass the evaluation,

you will sign the COURSE DECLARATION FORM

and your instructor will certify you with PTRD 1 Star Nitrox Diver,

which accredits you to:

  • To dive up to -30 mt without decompression without the need for supervision of a PTRD instructor or PTRD Dive Leader.

  • In places with conditions like where you’ve trained without additional training,

  • During the day,

  • Where vertical and direct surface ascent is possible,

  • With appropriate surface assistance (people who can assist divers)

  • Using air or Nitrox 32.

If you can’t successfully complete any of the training sections, check with your instructor for the options available, either the certification of a lower degree or the possibility to finish your course at another center.
