Technical Diver 1

This course will enable you to dive beyond the limits of recreational diving. In Technical Diving 1 you will be able to use the skills learnt from Technical Diving Basic Skills in real scenarios.  You will also be able to make more complex diving and you will learn how to handle accelerated decompression using up to 100% oxygen.  The Technical Diving 1 course will also allow you to use tri-mix which is beneficial to reduce narcosis and a more easy breathing at depth.  The introduction of standard gasses will allow you to plan the dive efficiently and safely and will also reduce confusion when diving with a big team.

After successful completion of the course, you have learned to :

  • Plan and perform decompression with an extra decompression gas.
  • Use helium-based bottom gases.
  • Maximum PO2 1.6 for decompression gas.
  • Maximum PO2 1.4 for the bottom gas.
  • Equivalent narcosis depth (END) during the course is 30 meters.
  • Accelerated decompression using EAN50 or 100% oxygen.
  • Dive to a depth of 55 meters.
