Learn scuba diving's extreme sport!

Technical diving courses are beyond mainstream recreational diving by PADI. Learn more with TecRec Diving.

Technical diving is scuba diving’s “extreme” sport, taking experienced and qualified divers far deeper than in mainstream recreational diving. Technical diving is marked by significantly more equipment and training requirements to manage the additional hazard this type of diving entails. Tec diving isn’t for everyone, but for those who hear its challenge call, the PADI TecRec courses are the answer.

What is technical diving?

Technical scuba diving is defined as diving other than conventional commercial or research diving that takes divers beyond recreational scuba diving limits. It is further defined as and includes one or more of the following:

  • diving beyond 40 metres/130 feet deep
  • required stage decompression
  • diving in an overhead environment beyond 40 linear metres/130 linear feet of the surface
  • accelerated decompression and or the use of variable gas mixtures during the dive

Because in technical diving the surface is effectively inaccessible in an emergency, tec divers use extensive methodologies and technologies and training to manage the added risks. Even with these, however, tec diving admittedly has more risk, potential hazard and shorter critical error chains than does recreational scuba diving

Although TecRec is not the first technical diving program (cave diver training has been around for decades), it repeatedly receives accolades for its merits.


  • TecRec courses are integrated into an instructionally valid, seamless course flow that takes you from beginning tec diver to one qualified to the outer reaches of sport diving using different gas mixes.
  • Each level introduces you to new gear, planning and procedures appropriate to extend your diving limits.
  • Discover Tec is designed as introduction to technical diving and can be carried out in the Local Pool or in a Open Water Environment
  • The Tec Diver courses are an integrated sequence of three subcourses: 
  • Tec 40Tec 45 and Tec 50.  You can complete them continuously, or you can complete each level separately with a time span between them.  This gives you learning efficiency, instructional integrity and schedule flexibility.
