PADI's most popular specialty is the PADI Enriched Air Diver course. Diving with enriched air nitrox lets you safely extend your no stop time beyond the no decompression limits for air. Diving with enriched air means more time underwater, but you need to be certified as an Enriched Air Diver to get enriched air fills or certified as a DSAT Gas Blender.

With both Nitrox / Enriched Air being so popular and the number of technical divers is on the rise, which means that lots of scuba divers want enriched air and gas blends. The Tec Gas Blender course teaches you to blend enriched air nitrox and helium-blend gases using one or more blending methods. Being the blender is a key job at a busy PADI Dive Center or Resort and your work allows other divers to do what they love to do - scuba dive.
