About my Deco50 technical diving course

My Deco50 technical diving course provides students with the knowledge and skill proficiency to conduct normoxic trimix accelerated decompression diving.

This tech diving training is globally recognized for its uncompromising standards and very high diving competency development. On this course, renowned technical diving instructor, Andy Davis delivers world-class tech certification to the highest possible standards. This tech diving course is held in Subic Bay, Philippines.

Preliminary course theory is delivered through eLearning, with 6 online manuals, quizzes, and exams. This is then developed with instructor-delivered lectures, discussions, scenario case studies, and team debriefs. The practical training phases of the course consist of dry land drills, confined water skills practice, and 5 intensive training dives (typically 600+ minutes total in water).

What are the Deco50 technical diving course limits?

This technical diving course is a gateway into full technical diving. It certifies divers to safely conduct trimix accelerated decompression dives to a maximum depth of 50m (165ft), with 30 minutes max deco and 1 deco gas.

What is trimix and why use it?

Trimix is a breathing gas for deeper technical dives that adds helium to increase dive safety by reducing gas density, alleviating the effects of narcosis, and, where necessary, reducing the fraction of oxygen breathed to eliminate the risk of O2 toxicity.

Gas density: there are recommended limits on gas density to prevent excessive accumulation of Co2 in the body tissues (hypercapnia). Co2 is 25x more narcotic than nitrogen; CO2 narcosis during a technical dive can become debilitating,

Narcosis management: while many scuba divers feel tolerant of the narcosis effect when diving air at depths between 30-40m (100-130ft), the impact of narcosis when attempting to conduct complex and risk-consequential technical dives can become an impediment to diver safety.
