TDI Advanced Trimix Diver Course

Ready to Conquer the Deep?

Have you ever stared at a pristine deep wreck or untouched reef at 60 meters and thought, “I wish I could go further”?

Do you want the skills, confidence, and freedom to safely explore depths most divers only dream about up to 100 meters

The TDI Advanced Trimix Diver Course is the pinnacle of open-circuit technical diving training. This is where serious divers become true explorers, mastering the planning, equipment, and precise execution required for deep, helium-based dives beyond recreational limits.

You’ll learn to:

• Research and plan complex multi-gas dives
• Manage multiple stage bottles and advanced gas switches
• Handle the physiological challenges of extreme depth (narcosis, high-pressure nervous syndrome, longer decompression)
• Conduct safe, team-based dives to 100 metrers with trimix breathing mixes

This course can be structured as a structured program or a personalized mentorship-style experience—building real-world skills through progressive experience dives along the way.

Perfect for divers chasing:

• Legendary deep wrecks
• Remote, untouched reefs
• Technical exploration that pushes the boundaries of human capability

After completing Trimix (60m) and gaining solid experience, Advanced Trimix sets the stage for the most advanced levels of technical diving—deeper, safer, and more rewarding than ever.

The deep ocean is calling. Answer it with the skills and confidence only TDI Advanced Trimix can give you.
