The course is well suited to experienced recreational divers and those seeking comprehensive wreck penetration diving skills, along with access to more refined equipment configurations and gas options.  It can be defined as ‘advanced recreational’ or ‘tecreational’ level training.  It is also designed to provide a solid foundation for higher level wreck penetration training (technical wreck).

Key Outcomes:

  • Use of redundant breathing systems (‘Intro-to-Doubles’ included on the course, if desired)
  • Precision Dive Planning and Gas Management
  • Team Diving Skills and Effective In-Water Communication
  • Penetration Guideline and Overhead Environment Emergency Skills

Training dives include; One (1) Confined Water, One (1) Open Water Dive and Three (3) Overhead Environment/Penetration Dives.  Penetration is permitted within the light zone only, in clear view of an unobstructed exit point and no restrictions where divers cannot pass through together whilst sharing air.
