As a PADI Open Water SCUBA Instructor, one of the coolest things is staying active and up to speed on a wide variety of dive specialties. Most recently, I have begun teaching the PADI Enriched Air (EANx) Nitrox Specialty Course. If you don’t dive with Nitrox, consider this. First, although strict depth limits must be observed based on your breathing gas blend, Nitrox can significantly reduce your exposure to nitrogen, leading to longer no-stop bottom times, enhanced margin of safety with regard to decompression sickness and other benefits.
