How the course works

The Tec40 course is a brilliant choice for anyone interested in getting involved in tec diving. It only takes 4 days to complete and introduces you to all the basics of technical diving from equipment configuration, dive planning, gas switching and decompression.

  • Day 1 is a day of theory and discussion. We talk through all the equipment used for tec diving and explain the different configuration choices. We also talk through decompression models, gas planning and emergency situations as well as all the other special aspects of technical diving.
  • Day 2 we continue the theory with dive planning and then head to the pool in the afternoon for some skills practice, including valve shutdown drills, gas switching and gas sharing.
  • Day 3 is spent at an inland site further practicing skills and calculating gas consumption rates. You wil also get used to diving in the technical rig in relatively shallow water.
  • Day 4 you'll conduct a simulated deco dive and then finally a full decompression dive to 40m where you'll put everything you've learned into practice.

At the end of the course you'll be qualified to dive to 40 metres and manage up to 10 minutes of decompression.
