This class teaches the proper techniques to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.

This course is for the certified Advanced Nitrox/Decompression Procedures diver that needs to extend their depth range, or is looking for the next step in technical dive training.

Course prerequisites:

Advanced Nitrox diver and Decompression Procedures diver with 100 logged dives (25 of which must be deeper than 30m/100ft), minimum age 18

What will I learn?

Over a minimum of 4 dives and several theory sessions you’ll cover

  • History of deep air diving
  • Physics and physiology
  • Decompression Options – air, nitrox and or oxygen
  • Decompression dive planning
  • Decompression diving procedures – including predive checks and drills; team awareness and communication, following a decompression schedule; gas switching; SMB deployment
  • Proper trim, buoyancy and finning techniques
  • Management of multiple decompression/stage cylinders
  • Emergency procedures - equipment failures, catastrophic gas loss, omitted decompression, navigational errors, injured/unconscious diver
