Technical diving has become very popular for divers wanting to go that bit deeper and/or that bit longer. It offers you the ability to go to sites that are less well known and less crowded and enjoy them for longer.
Tec Diver offers the range of PADI & TDI Tec courses on both Open Circuit and Closed Circuit SCUBA

New to Technical Diving?

Technical scuba diving involves going beyond recreational scuba diving limits and includes one or more of the following:
  • Required decompression
  • Diving in an overhead environment beyond 40 linear metres/130 linear feet of the surface
  • Use of variable gas mixtures during the dive
  • Use of extensive equipment and technologies


In technical diving the surface is often inaccessible in an emergency, so tec divers use extensive procedures, equipment and training to manage the added risks and potential hazards.

We offer the range of Tec courses for people wanting to start or further their technical diving skills and qualifications.
