The Advanced Mixed Gas Diver course is a great way to extend already considerable open-circuit mixed gas diving skills.
The course considers the detailed theory and practice of the decompression strategies needed to dive safely to 80 metres.
Who is it for
Advanced Mixed Gas Diver (80m) course is the ultimate step in BSAC open-circuit mixed-gas training. It introduces a Sport Mixed Gas Diver (50m) or Explorer Mixed Gas Diver (60m) to diving with an extended choice of trimix gases, and qualifies them to dive such mixes to depths of up to 80m, using a twin-set and a minimum of two stage cylinders.
To enrol on the Advanced Mixed Gas Diver (80m) course you must be at least 18 years old and be a Sports Diver with 35m depth certification. You also need to have completed a 50mtr mixed Gas Diver course (Any agency). You should be very proficient at deeper diving, with say 100 or more logged dives.
If you are already an Explorer Mixed Gas Diver(60m) or 60mtr Trimix rated diver with other agencies, some of the course elements are discretionary.
The Skills you’ll Learn
You will extend the breathing gas mixes that you can use, learning to use hyperoxic, normoxic and hypoxic trimix in sequence to minimise the narcosis you would otherwise suffer at depth.
You will learn to plan and conduct dives to 80m, and extend your practical diving skills to manage increasingly long run times with ascent times of up to 60 minutes.
You will develop your knowledge of deep open-circuit mixed-gas diving, including:
- Practical diving techniques, including using decompression systems suitable for expedition team diving.
- Advanced diving physiology.
- Advanced decompression theory.
- Deep dive planning including gas choices, gas-loss management and run-time schedules.
The Advanced Mixed Gas Diver (80m) course includes six theory sessions and a theory assessment, and a dry practical session on kit preparation. One or more sheltered-water lessons will cover drills and skills. Then you will spend at least 300 minutes on five open-water training dives to give you plenty of in-water time to practise the skills and discipline needed to carry out deeper mixed-gas diving.
If you are an Explorer Mixed Gas Diver (60m), some of the theory sessions and open-water dives may not be necessary, depending on your level of deep-diving experience and familiarity with the dive kit appropriate for an 80m dive.
This is a continually assessed course during which students must reach the required performance standards.
What you’ll be able to do
An Advanced Mixed Gas Diver (80m) is competent to plan conduct open-circuit dives with mandatory decompression using hypoxic, normoxic and hyperoxic trimix to dive to a maximum depth of 80m.
This course is 3 days so you must be already qualified to 60mtr.
Cost is £500 includes course pack, excludes all other costs and gases including a share of instructor gases.
Minimum numbers is 1, max number is 2.
