REBREATHER DIVING: ADVANCED MIXED GAS COURSE
OVERVIEW
This course will train the divers to use hypoxic trimix (less then 16%) in diluents and bailouts to a maximum depth of 330ft/100m. The Advanced Mixed Gas CCR Diver course is a mainly a continuation of the knowledge and practical skills learned in the Mixed Gas CCR Diver course. The aim of the course is develop the skills required to use the Evolution/ Inspiration CCR at depths beyond the normoxic limits uof the water column. Learn the advanced requirements of closed circuit dive planning including bailout options and correct hypoxic and normoxic diluent selections.
Course Prerequisites
Have completed a mixed gas CCR course on the Evolution/Inspiration from a recognized agency. Must have a minimum of 200 logged dives. Minimum of 100 hrs on rebreather distributed over a minimum of 100 dives with 60% of the dives deeper then 100ft/30m.
Course Structure:
A minimum of 320mins of underwater time will be required to complete this course.
Day 1 - Classroom session to review mixed gas CCR theory and cover the theory specific to CCR diving using hypoxic helium based diluents.1 dive 33ft/10m - 66ft/20m. Equipment configuration drills.
