Correctly mixing gasses is essential to being able to breathe safely underwater. The SSI Gas Blender program teaches you the skills and concepts required to safely blend nitrox and helium-based trimix gases. This non-diving program is open to certified and uncertified divers and teaches proper usage of mathematics, gas blending software, physics, and techniques required to blend breathing gases safely. Upon completing this program, you will earn either the SSI Nitrox Gas Blender or SSI Trimix Gas Blender certification.
