Why take the DSAT Tec 40? 

If you're interested in technical diving, but haven't yet met the prerequisites for the Tec 50 course, you can consider enrolling in the DSAT Tec 40. It is the first rung in the Tec Deep ladder, the first subdivision of the full PADI Tec Deep Diver course consists of the first four dives.

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. You will 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.

Most people learn technical diving in backmount (both cylinders located on back), if you want to take this course and in sidemount (one cylinder located separately under each arm) and find out why side mount configuration is superior. Visit www.sidemountscubadiving.com for more information.

What do I need to start?

  • PADI Advanced Open Water Diver (or equivalent)
  • PADI Enriched Air Diver (or equivalent)
  • PADI Deep Diver (or equivalent)
  • Have a minimum of 50 logged dives, of which at least 10 must be enriched air dives, 12 must be deeper than 18 metres/60 feet and at least six must be deeper than 30 metres/100 feet
  • Minimum age: 18 years old
  • Obtain a dive medical signed by a physician
What will I Do?

By the end you will be qualified to 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 Tec 50 course, your Tec 40 can credit towards the Tec 45 or Tec 50.

What will I need?

Tec Deep Student Crew-Pak, which includes student manual, planning slate and checklist slate (need a few weeks before the start of the Course to allow you time to complete all Knowledge Reviews etc)

Calendar shows where I will be and duration of my time there. If I am in your area and you want to join a course, contact me for locations. If you see any dates free and would like me to visit your dive centre or location, drop me an email with location, course interest and possible dates.
Want to know more about how your cylinders weight changes during a dive..? Video has information on what effects the weight change and has tests showing cylinders at different air pressures during dives in salt and fresh water. It displays whether they have Negative, Neutral or Positive Buoyancy. More details found at www.sidemountscubadiving.com
