TDI Decompression Procedures / Advanced Nitrox Course

  • Regular price $1,695.00
Tax included. Shipping calculated at checkout.

The Decompression Procedures program trains you in the planning and conduct of staged decompression using the most common equipment requirements, gear set-ups and decompression techniques to a depth of 45m.

Combined with TDI Advanced Nitrox Course, this program is ideal for those divers who want to conduct deeper dives associated with staged decompression using nitrox mixes.

The Advanced Nitrox program will train you in the benefits, hazards and proper procedures for using EAN 21 through 100% (oxygen) for dives to 4om (up to 45m when combined with Deco Procedures).  You will need to provide all your own dive equipment, including cylinders and stage regs.

If you are not Nitrox qualified, you will need to complete one evening of basic nitrox theory prior to commencing this programme as your first two dives on the course will be using nitrox as a bottom gas. This program is for experienced divers, not novices.

Many student doing this course are also interested in completing the SDI Solo Diver Course.  When booked in conjunction with either the Adv Nitrox or Deco course this program is offered at a special price of only $250.  Ask for more details when booking!
