PADI Tec 45 Diver

The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

You continue fine-tuning gas planning and calculating accelerated decompression stops. Plus, you learn to think like a technical diver.

• Prepare for and respond to foreseeable technical diving emergencies
• Master the basic skills and procedures you’ll need as you move into deeper technical diving


You’ll use full technical equipment, which includes wings and doubles plus an additional deco cylinder, or you may use a technical sidemount configuration. Your PADI Tec Deep Instructor will explain the gear required for your tec diving adventures.
