Course
The IANTD Normoxic Trimix Diver course is structured to train divers who wish to dive to a depth between 40 and 60 meters with open gear, using trimix mixtures that allow them not to be susceptible to any form of narcosis, or keeping it within low and controlled limits .
The course is therefore suitable for those who do not want to breathe compressed air at depths greater than 40 meters or suffer its narcotic effects.
Overview of exchange rates
The IANTD Normoxic Trimix Diver is designed to train divers to safely use trimix mixtures down to a depth of 60m.60m.
The benefits of using a trimix mix essentially come from reducing the percentage of nitrogen in it.
In its place is placed a percentage of helium, which is a much less narcosis-producing gas than nitrogen, and affords various advantages, the chief of which is the retention of clarity in depth.
Topics covered include history of gas diving, physics, physiology, equipment setup, training, dive charts, repetitive dive calculations.
Hands-on sessions include how to safely handle trimix mixes, how to analyze them, confined water training and three (3) dives.
The IANTD Normoxic Trimix Diver course increases students’ general knowledge of diving.
At the end of the course, the International Association of Nitrox and Technical Divers will issue a corresponding patent.
Course prerequisites
- Possess IANTD Advanced EANx Diver certification or equivalent.
- Be 18 years old.
Educational materials for the course
During the course it is mandatory to use the IANTD NORMOXIC TRIMIX DIVER manual with the relevant dive tables and analysis stickers.
Dives must be recorded in the appropriate dive log and signed by the instructor.
Duration of the course
Five (5) theory lessons, closed water, three (3) dives with mixtures with a maximum of 30% helium (He) and a minimum of 20% oxygen (O2) at a maximum depth of 60 m.
