IANTD Advanced Rec Trimix program

During this 4 days we discus about, diving physics and physiology, dive equipment – configurations and dive planning including the use of decompression software.

A large emphasize is laid on gas management, team diving and self discipline. The theory will be finished with an exam where a minimum score of 80% is required.

1 confined water session and 4 open water dives, 2 of which will be to depths between 30 and maximum 48 meter.

During the open water dives we will practice a variety of dive techniques including gas switch training to a decompression gas. The open water dives will be made with mixtures between 21 and 39%, stops are made with EANx mixtures between 40 and 50%.

Where appropriate dives will be made on Rec Trimix mixtures.

Rated 5 out of 5
I did my IANTD advanced eanx diver as well as their homemade PADI PPB XTend course. Both were really challenging and as a diver, I learned a lot! Harry was my instructor and his experience, dedication and professionalism are beyond imagination. I really liked everything about the courses and dives.
