Continue your Tec adventure
Once you’ve successfully completed Tec 40 or equivalent, it’s time to move to step two of your technical diver training with the Tec 45 Trimix course.
As you cross into the 40-45m depth range the use of helium in your diving mix is important to combat the very noticeable effects of narcosis and increased gas density.
