TDI Decompression Procedures Course

Serious about your deep diving, want to really learn all about staged decompression to 45m, this is for you...
Frog Dive generally offers this course in conjunction with the TDI Advanced Nitrox Diver Course for those divers wanting to really learn all about the benefits of using higher concentrations of Nitrox for staged decompression dives.

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


When combined with TDI Advanced Nitrox this program is ideal for those divers who are already conducting deeper dives, but want to better understand staged decompression using nitrox as a decompression gas, particularly when diving the deeper wrecks off Sydney.

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.
