Standard

PTRD Two Stars Diver

  1. Aim of the training programme

1.1 This training programme aims to build on the skills learned during the one star fundamentals of

SCUBA diving and advance the skills in recreational SCUBA diving such as deeper diving and

night diving activities, whilst using air or Nitrox-40 as a breathing gas, to a recommended maximum depth of

PpO2=1,4 b + deep national regulation, meters in a safe and competent manner.

.

  1. Classification

  1. Competencies of a certified PTRD Two Star Diver

4.1 A PTRD Two Star Diver shall be trained such that when assessed by a PTRD Instructor,

he shall be deemed to have sufficient knowledge, skill and experience to procure air,

equipment, and other diving services and to plan, conduct, and log advanced open-water

dives that do not require mandatory in-water decompression stops, without the supervision

of a PTRD Instructor or PTRD Dive Leader, when properly equipped and accompanied by

another certified diver of at least the same level, provided the diving activities undertaken,

the diving conditions and the diving area are similar, equal or better to those in which

training was received.
