Ready to go beyond recreational diving?
Start your journey into technical diving with PADI's full range of Tec programs. From sidemount setups to 90 meters Trimix dives, each course builds your knowledge, safety and diving capability step by step.
Tec 40
Take your first step into the world of technical diving.
Tec 40 introduces you to longer time at depths, extended no-stop limits, and the use of specialized gear. This course bridges the gap between recreational and technical diving and sets the foundation for all future Tec training.
✅ Learn basic decompression procedures and gas management
✅ Hands-on training with backmount or sidemount configurations
✅ Develop your skills in planning, problem-solving, and safety
Tec 40 Trimix
Explore deeper with added safety and mental clarity.
Tec 40 Trimix builds on the standard Tec 40 course, introducing helium-based breathing mixes to reduce narcosis. It’s the ideal course for divers who want greater comfort and control at depth.
✅ Use Trimix blends (21-35% O2) to manage narcosis
✅ More precise dive planning with multi-gas exposure
✅ A strong step toward deeper Tec and Trimix programs
Tec 45
Take your Tec training deeper and more advanced.
Tec 45 pushes your technical skills further with full decompression procedures and deeper dives. You’ll learn bailout planning, stage bottle use, and more advanced problem-solving under pressure.
✅ Dive to 45m using single or multiple gas mixes
✅ Train for longer, more complex decompression dives
✅ Build confidence and control under real-world conditions
Tec 45 Trimix
Increase safety and comfort on your deeper dives with Trimix.
This course adds helium to your Tec 45 training, reducing narcosis and improving focus and clarity on dives up to 45m.
✅ Dive to 45m using trimix with higher oxygen and helium blends
✅ Focus on precision gas planning and controlled execution
✅ Build advanced confidence in demanding conditions
Tec 50
Complete your core technical diver training.
Tec 50 is the final step in the foundational Tec Diver path, enabling you to dive to 50m with full decompression and advanced equipment configurations.
✅ Plan and execute deep dives with backup gases and decompression
✅ Learn to respond to equipment failures and emergencies
✅ Essential for entry into Trimix and full deep diving programs
Tec 50 Trimix
Reduce risk and improve comfort at 50m with normoxic Trimix.
Add trimix to your Tec 50 training to gain better control and reduce gas density and narcosis at depth.
✅ Use helium to minimize narcosis during extended deep dives
✅ Enhance planning, gas switches, and safety procedures
✅ A smooth transition to advanced Trimix levels
Tec 40, 45, 50
A complete technical diving foundation — all in one course.
Tec Tec 40, 45, and 50 into a single structured program. It’s ideal for committed divers who want to develop their full technical capacity from start to finish.
✅ Dive to 50m with staged decompression and full redundancy
✅ Train progressively through all three core Tec levels
✅ Builds strong habits, safety skills, and situational awareness
Tec 40, 45, 50 Trimix
The full technical path, including helium-based dives.
Tec Deep Trimix gives you the same full training path as Tec Deep — with the added safety and performance of using trimix throughout.
✅ Learn and apply trimix at every level of Tec training
✅ Improve focus, reduce narcosis, and increase dive
comfort
✅ Ideal for committed divers aiming for serious depth
Tec Trimix 65
Extend your limits with normoxic Trimix diving to 65m.
This advanced course is for experienced Tec divers who want to explore deeper dives while managing multiple gases and extensive decompression.
✅ Dive safely to 65m using normoxic trimix
✅ Master advanced gas planning, dive execution, and contingencies
✅ Prepares you for Full Trimix and exploration-level diving
Tec Trimix Diver
The highest level of open-circuit technical diving.
Learn to dive beyond 90m using hypoxic trimix and fully customized gas mixes. This course is designed for elite divers who demand precision and safety at extreme depths.
✅ Dive beyond 90m with custom trimix blends
✅ Train in advanced decompression and dive planning
✅ Suitable for exploration, research, or advanced expedition diving
Tec Sidemount
Improve your safety, flexibility, and streamlining underwater.
Tec Sidemount introduces you to sidemount equipment configuration — a powerful tool for technical and cave diving. Learn to handle multiple tanks while reducing gear drag and increasing control.
✅ Configure and manage 2–6 cylinders with sidemount
✅ Perfect foundation for all Tec diving
✅ Greater mobility, redundancy, and dive options
