By Eduardo Macedo of SCUBA DIVING UNLIMITED
This month we held the course Tec Blender Nitrox/Trimix where students of Scuba Du (Tec Rec Center) learned the alchemy of gas mixtures.
On the course the candidates, all technical divers in open circuit and closed circuit, learned how to make their own blends of Nitrox and Trimix for continuous flow, partial pressure, use of oxygen booster and gas transfer wires.
They learned to calculate their mixtures by formulas and planning with gas mixtures software.
Now, in combination with knowing more than how to mix, the candidates use of the oxygen and helium analyzer gives one more level of redundancy, increasing the safety of diving and avoiding the use of wrong mixtures.
