Tec Deep Diver

This short course is designed to let divers experience technical diving in confined water. Get introduced a few basic skills and procedures. Discover Tec may credit towards the Tec 40 course.

Curious about technical (tec) diving, but not sure about jumping into a course? Discover Tec is a short confined water experience that allows you to give technical diving a try. You get to wear all the extra tec diving gear and take it for a test dive.

Upon completion of the Tec Deep Diver Course you become a Certified Tec Diver


  • Make four actual decompression dives as deep as 50 metres/165 feet
  • Use enriched air nitrox and/or oxygen for decompression
  • Use desk top decompression software to create custom dive tables and plan your dives
  • Qualify to make technical decompression dives independently
  • Scubadeep’s Tec Instructor will explain the equipment you’ll use and go over basic tec diving procedures, such as the importance of diving in teams. You’ll get in the water, make gear adjustments, then simply explore and get a feel for the equipment.


You’ll start with your basic scuba diving equipment and add technical equipment, which essentially means you’ll begin to double up on gear. You may dive with backmounted or sidemounted cylinders. Our Scubadeep’s Professional team of Tec Instructor will have you dive with EANx for additional conservatism.
