Hypoxic Trimix Diver

The Hypoxic Trimix Open Circuit course and the Limited Hypoxic Trimix Open Circuit course is an advanced diving course designed to equip divers with the skills and knowledge necessary to plan and execute dives to depths greater than 60m/200ft.

This course builds upon the theoretical knowledge and skills learned in previous diving courses and introduces new techniques specific to deep decompression diving. Throughout the course, divers will review and refine their existing skills, such as gas switching, buoyancy control, stage cylinder exchange, and SMB deployment.

The course emphasizes the importance of proper equipment setup, gas analysis and labeling, as well as effective communication and problem-solving techniques. By the end of the course, divers will have the confidence and competence to safely navigate the challenges of deep open circuit mixed gas diving.

This course is designed to safely train students to:

• Dive to a maximum depth of 100m / 330ft using open circuit scuba, depending on the course level taken.
• Use air, nitrox, oxygen, and trimix mixes as breathing gas.
• The END/EAD for all gases must not exceed 30m/100ft or a PO2 of 1.4 for bottom mixes, 1.6 for decompression mixes.
• Complete optimized decompression dives within gas planning protocols, without any time limitations.
• Use up to four decompression gases of up to 100% oxygen for optimized decompression obligations.
• Use a “travel gas” when using hypoxic gas mixes.
• This program is a technical program for twinset and technical sidemount divers only.
