GUE TECHNICAL DIVER 2 Move towards high level exploration and project diving.

The GUE Tech 2 Course at Tech Asia

GUE’s Technical Diver 2 course is designed to enhance deep diving proficiency while using helium breathing gases and oxygen-enriched decompression gases.

It is a rigorous class designed to prepare divers for depths of 75 m/246 ft and beyond, using multiple (three or more) stages or decompression gasses, to manage their gas, bottom time, and decompression exposure in a safe and comfortable manner.

Prerequisites - the applicant must :

  • Be a minimum of 18 years of age.
  • Be physically and mentally fit and a non-smoker.
  • Be able to swim.
  • Obtain a physician’s prior written authorization for use of prescription drugs, except for birth control, or for any medical condition that may pose a risk while diving.
  • Have passed the GUE Tech 1 course.
  • Must have a minimum of 25 logged Tech 1 level dives beyond GUE Tech 1 certification.
  • Have logged 50 dives in a double tank configuration.
  • Hold insurance that will cover diving emergencies such as hyperbaric treatment, e.g., from
    Dive Assure, DAN or equivalent.

What You Will Learn

You will, amongst other things, be learning about :

  • Advanced mixed gas diving including hypoxic protocols.
  • Risks of decompression diving.
  • Gas management during deep dives.
  • Accelerated, omitted, and general decompression strategies.
  • Deep diving logistics and planning.

Land drills cover such aspects as :

  • Dive team order and protocols.
  • Gas switching procedures and protocols, including hypoxic protocol.
  • Back gas and stage regulators/valve failure modes and management.
  • Use of a bottom stage and multiple decompression stages (tank rotations).
  • Unconscious diver recovery.
  • Decompression gas sharing.

All of this is intergrated in to your actual training and experience dives.

Course Duration

The Technical Diver Level 2 course is normally conducted over six days. It requires a minimum of seven dives (including three trimix experience dives) and at least 48 hours of instruction, encompassing classroom lectures, land drills and in-water work.
