Once you’ve successfully completed your Fundamentals course with a Rec pass, you’re ready to start your technical diver training with the Tec 45 Trimix course.
As you cross over from the recreational to technical depth range the use of helium in your diving mix is important to combat the very noticeable effects of narcosis and increased gas density. During technical dives it’s critical to be alert and able to respond effectively if problems arise. Diver safety is paramount, and so, at Dive Centre Manly, Trimix is an important and integral gas choice for all technical dives. Not only will this increase your clarity and enjoyment of dives in the technical range it will also give you a qualification to use light helium mixtures.
*Prior to the start of the course please consult us about equipment packages and options to suit you.
