PDIC's Tek Nitrox class includes decompression training. PDIC's philosophy is the "complete course concept" for all levels of diving. For example, in PDIC open water courses the student should receive all pertinent rescue training. For the advanced nitrox/deco classes, the PDIC title is Tek Nitrox which suggests a max ppO2 of 1.4 ATA on Nitrox 26. Decompression is suggested to be no greater than 30 minutes in open water environments. The minimum age for the course is 18 years of age. Deco gases are from Nitrox 40 to 100% O2 for deco.
Once I took the job of technical training director, I removed this course from current training for new technical instructors. Older technical instructors teaching thius program may still continue to do so, but PDIC's official push is that the student must pass a tek prep course and then may enter Tech 1: Triox with 30/30 and 25/25 and 1 deco bottle or Cave 1 which is like intro in doubles with 1 jump.
Thanks Trace.
