Years ago the terms “Trimix” and “recreational” seemed paradoxical to divers. Trimix was considered to be the domain for extreme divers wishing to go way beyond the depths regarded as safe for recreational divers. The gas for risk-takers prepared to endure long decompression stops in order to make a safe ascent.
Knowledge development of Tri-MIx use and the introduction of reliable Trimix dive computers plus the increasing availability of the gas at ever more affordable prices has caused many divers to think again.
After all, you are already diving with Nitrox and have learned that with a little care when analysing the gas, it offers many advantages over air. You have already adapted your equipment to be compatible with oxygen-rich gas mixes. Is Trimix so very different?
The recreational Trimix course will allow you to become familiar with using a three gas mix containing the same oxygen content as air but a reduced nitrogen quantity due to the inclusion of helium. It is as easy as diving with Nitrox which is why some divers are calling it Triox. The advantage in his use are less narcosis and breathing effortlessness.
