The PADI Enriched Air Diver course is PADI’s most popular specialty scuba diving course, and it’s easy to see why. Scuba diving with enriched air nitrox gives you more no decompression dive time. This means more time underwater, especially on repetitive scuba dives. You can typically stay down longer and get back the water sooner. No wonder many divers choose this as their very first specialty. Diving with enriched air nitrox benefits all types of diving, but it goes especially well with these specialties: PADI Wreck Diver course – Popular wrecks tend to be deeper, so enriched air nitrox maximizes your exploration time. PADI Deep Diver course – The deeper you dive, the shorter your no stop time – but enriched air nitrox increases it, giving your more time at depth PADI Digital Underwater Photographer – Photographers usually like to make several dives so they can get lots of pictures. Enriched air nitrox reduces the amount of residual nitrogen you accumulate, allowing repetitive dives to be longer. PADI Master Scuba Diver The PADI Enriched Air Diver course counts toward your Master Scuba Diver rating -- the highest non professional rating in recreational diving.
