TDI NITROX DIVER COURSE
DURATION
1 day
IN A NUTSHELL
The TDI Nitrox Diver course is designed for divers who want to use enriched air nitrox (EAN) to enhance safety and extend bottom time. This training teaches you how to analyze your gas mix, understand the benefits and risks of oxygen, and use dive tables or computers suited for nitrox blends ranging from 22% to 40% oxygen.
Using nitrox helps reduce nitrogen absorption, allowing for longer no-decompression limits or shorter surface intervals. However, it also requires a solid understanding of oxygen toxicity and depth limitations.
PRE-REQUISITES
Students must be 18 years old, and:
-
certified as an SDI Open Water Scuba Diver (or equivalent)
SUBJECT AREAS
During the TDI Nitrox Diver course, we focus on the following key areas: Theory - Advantages and disadvantages of nitrox - Oxygen and nitrogen physiology - Principles of partial pressure and equivalent air depth (EAD) - Calculation of maximum operating depth (MOD) - Equipment considerations and compatibility - Gas analysis and safety procedures - Myths and realities of nitrox use Practical Skills - Proper analysis and identification of nitrox mixes - Use of nitrox dive tables and compatible computers - Dive planning and gas management - Filling procedures and cylinder labeling - Setting up and verifying dive computers
MEET NEW CHALLENGES
Switching to enriched air nitrox represents a step forward in dive management. With increased oxygen content, it becomes essential to understand depth limitations and the risks associated with oxygen toxicity, especially during extended exposures. Using nitrox requires greater planning discipline, including gas mix verification, proper dive computer settings, and strict adherence to safety protocols. This course will provide you with the knowledge and skills to safely maximize the benefits of nitrox, whether for longer dives without decompression or more efficient surface intervals between dives.
COURSE DURATION
The TDI Nitrox Diver Course has a duration of 1 day.
