REBREATHER EXPLORER (ERE LEVEL 4-5)

This is an extensive training program consisting of some 30-hours of theory and between six and 10 dives to prepare the Technical Rebreather diver for the use of Helium and other possible gases in deep exploration.

The operational depth limit for Level 5 program is extended to 100 msw. This is an equipment and skill-intensive course requiring extensive counseling by the ANDI Technical Instructor.

These courses take you from a non-rebreather / CCR diver through to trimix training. Please contact us for more information and see the table which shows you the qualification limits and standards for these courses
