TECHNICAL DIVING COURSES

A-1 Technical Diving Courses In Denver


Technical diving means going beyond recreational scuba diving limits. But, tec divers will tell you that it’s really about the challenge and adventure of exploring places that no one else has ever seen.

What is technical diving?

Technical scuba diving involves going beyond recreational scuba diving limits.

Technical scuba diving involves going beyond recreational scuba diving limits and includes one or more of the following:

  • Diving beyond 40 meters/130 feet
  • Required stage decompression
  • Diving in an overhead environment beyond 40 linear meters/130 linear feet of the surface
  • Accelerated decompression and/or the use of variable gas mixtures during the dive
  • Use of additional 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.   Get started with these SSI Extended Range programs.
