PADI Tec 40
The PADI Tec 40 Diver course is where you transition from recreational scuba diving to technical diving. It’s a great place to start because it’s the first subdivision of the full PADI Tec Diver course and bridges the gap between no stop diving and full technical deep decompression diving. You gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet.
You can consider enrolling in the PADI Tec 40 course if you’re interested in technical diving, but haven’t yet met the prerequisites for the PADI Tec 45 or PADI Tec 50 diver course. Because you can do one of these dives in confined water such as a swimming pool, many divers start the Tec 40 courses in the winter months, ready to continue in open water when spring arrives.
What will I do?
The Tec 40 course consists of three knowledge development sections, three practical application sessions and four training dives. You’ll learn about:
• Technical diving’s risks and responsibilities
• Technical diving equipment, proper rigging and set up
• Gas planning, oxygen limits and decompression planning
• Team diving techniques and emergency procedures, such as dealing with free flows, manifold leaks and out of gas situations
You will also learn to:
• Use decompression software and dive computers to plan and make decompression dives with no more than 10 minutes of total decompression and not deeper than 40 metres/130 feet.
• Use a single cylinder of decompression gas with up to 50 percent oxygen (EANx50) to add conservatism to the required decompression.
Since it’s part of the course, your PADI Tec 40 course training credits toward the PADI Tec 45 and Tec 50 courses.
NOTE: You PADI Tec Course includes 4 days of Technical Diver training, materials and gases up to 40%. However as with all training courses, certification has to be earned. Most students will complete the course within the 4 days, however additional training beyond this will be charged on a per day basis.
What scuba gear will I use?
You will use recreational scuba equipment, with some minor additions to enhance your ability to deal with tec diving conditions.
You may dive with backmounted or sidemounted cylinders. Your PADI Tec Instructor may have you dive with EANx for additional conservatism.
What are the prerequisites for this course?
To enroll in the Tec 40 course, you must be:
• A PADI Advanced Open Water Diver.
• A PADI Enriched Air Diver with at least 10 dives using enriched air deeper than 18 metres/60 feet.
• A PADI Deep Diver or proof of at least 10 dives to 30 metres/100 feet
• At least 18 years old and have a minimum of 30 logged dives.
You also need to have a Medical Statement signed by a physician within the last 12 months.
Note that qualifying certifications from other diver training organizations may apply – ask your PADI Tec Deep Instructor.
How do I start?
You’ll use the Tec Deep Diver Crew-Pak, which introduces you to:
• Tec diving lingo
• Emergency procedures
• Decompression and stage cylinder handling
• Gas planning
The pak includes a manual, dive planning checklist and dive planning slate. The optional Equipment Set-up and Key Skills video on DVD is a great tool to help you practice at home in between your tec diving adventures. You’ll continue to use the Tec Deep Diver Crew-Pak through Tec 50.
