Every nitrox or trimix fill starts with careful math, precise equipment handling, and a solid understanding of gas physics. The SSI Gas Blender program at Get-N-Wet Scuba teaches you how to safely produce the breathing gas that technical and recreational nitrox divers rely on. This is a non-diving, classroom and workshop-style program, which means it's open to certified divers and non-divers alike — you don't need to be a certified scuba diver to become a gas blender.

The course covers the mathematics of gas mixing, how to use gas blending software, the physics behind partial pressure blending, and the safe operating procedures required any time you're working with high-pressure oxygen and compressed gases. Depending on the track you choose, you'll earn either the SSI Nitrox Gas Blender or SSI Trimix Gas Blender certification — both recognized credentials for anyone looking to work at a dive shop, fill station, or technical diving operation.

FAQ

Do I need to be a certified diver to take the Gas Blender course?

No. This is a non-diving program, so it's open to both certified divers and non-divers who want to learn gas blending.

What's the difference between the Nitrox and Trimix Gas Blender certifications?

The Nitrox track focuses on blending oxygen-enriched air, while the Trimix track adds helium-based gas blending for technical diving applications.

Is this course useful if I just want to fill my own tanks?

Yes. Many recreational divers take this course simply to understand gas blending better or to safely produce their own nitrox fills.
