• Break through no-decompression limits
• Learn technical dive planning and gas management
• Experience staged decompression for the first time
• Train in Sidemount or Twinset configuration
• Develop strong buoyancy, trim, and awareness

The PADI Tec 40 course is about learning to dive with purpose, precision, and control. You’ll move beyond following a guide and start thinking like a technical diver—planning every detail of the dive before you ever enter the water.

Through theory sessions, confined water training, and open water dives, you will:

• Technical dive planning beyond no-decompression limits

• Foundational decompression theory and ascent strategies

• Accurate gas planning and consumption management

• Technical equipment configuration (sidemount or twinset)

• Precise buoyancy, trim, and stable hovering at depth

• Advanced propulsion techniques for control and efficiency

• Situational awareness and task loading management

• Controlled ascents and staged decompression procedures

• Gas-sharing and emergency response at depth

• Problem-solving skills under real technical diving conditions

Tec 40 doesn’t make you an expert—but it gives you the foundation, discipline, and mindset required to progress into deeper, more demanding technical diving.

The PADI Tec 40 course is for experienced recreational divers who feel ready to go beyond guided limits and take full control of their diving.

This course is ideal for you if you:

• Want to explore deeper dives with purpose, planning, and precision

• Are curious about technical diving and want a structured, safe introduction

• Enjoy mastering skills like buoyancy, trim, and situational awareness

• Want to learn how decompression diving really works

• Are interested in diving sidemount or twin tanks at an advanced level

• Plan to progress toward deeper technical certifications in the future

• Prefer disciplined, skill-focused training over “follow-the-leader” diving

Tec 40 is not about collecting a certification—it’s about changing how you dive. If you’re motivated, detail-oriented, and excited by the challenge of deeper, more complex dives, this course is your gateway into technical diving.
