Why become a DSAT Trimix Diver?

One of the biggest challenges with deep diving is dealing with Nitrogen Narcosis. This becomes an even bigger issue for technical divers as they dive deeper and the oxygen in the air that they breath becomes toxic. The solution to this problem is Trimix. Trimix is a mixture of Oxygen, Nitrogen and Helium. The Helium replaces some of the Nitrogen and Oxygen, thereby reducing the risk of Nitrogen Narcosis and Central Nervous System (CNS) hits due to oxygen toxicity. By taking the DSAT Trimix course, the technical diver is opened up to a whole new world of deep diving that was previously off-limites to air-breathing divers.

What do I need to start?

Students must be certified as a DSAT Tec Deep Diver or have a qualifying certification in deep decompression diving using air/enriched air from another organization *.

Students who qualify through a qualifying certification other than DSAT Tec Deep Diver must read the DSAT Tec Deep Diver Manual and complete the Knowledge Reviews prior to beginning the Tec Trimix Diver course.

What will I do?

The DSAT Tec Trimix Diver course is intended to extend the depth range available to technical divers trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 165 feet in open water. The DSAT Tec Trimix Diver course is intended for technical divers certified as DSAT Tec Deep Divers (or qualifying certification from another training organization). The course extends their depth range capabilities by training them in the use of trimix (helium, oxygen and nitrogen).

After successful completion of the DSAT Tec Trimix Diver course you'll be able to conduct gas-switch extended no-decompression dives, decompression dives and accelerated decompression dives using Trimix, Air and Nitrox beyond the technical depth of 165 feet. You'll also understand the hazards and risks involved in technical trimix diving, as well as how to prepare for and handle reasonable foreseeable technical diving emergencies. During training, the Trimix student is limited to 245 fsw but is unlimited after certification - experience withstanding.
