PADI Enriched Air (Nitrox/EANx) is the most popular PADI specialty certification worldwide. It replaces some of the nitrogen in standard air with extra oxygen. That means less nitrogen absorption, longer no-decompression limits, and less fatigue on repetitive dive days.
Unlike the SSI Nitrox course (theory-only), the PADI Enriched Air course includes 2 recommended Nitrox dives, so you see the extended NDLs on your dive computer right after the theory.
The course combines PADI eLearning theory with practical gas analysis training and 2 optional Nitrox dives.
Unlike the SSI Nitrox course, the PADI Enriched Air course includes 2 recommended Nitrox dives as part of the certification.
Coral gardens, moray eels, snappers, parrotfish. The primary training reef — gentle conditions and rich marine life.
British-era vessel thick with soft coral. Resident groupers, blue-spotted stingrays, moray eels. Light-zone penetration possible.
Rocky pinnacle with currents and pelagics. Eagle rays, drift diving. One of Goa's most dynamic dive sites.
Protected bay, very gentle. Nudibranchs, pipefish, seahorses. Ideal for skill-focused dives without current distraction.
Shallow reef for long bottom times. Macro life — nudibranchs, ornate ghost pipefish. Great for photography and hover practice.
Here's what actually sets us apart, minus the sales talk.
Pro-grade gear serviced every 100 dives or 6 months, not when it fails. MK25/S620 regulator, Hydros Pro BCD, Aladin Sport dive computer. You train on the same equipment working instructors use.
Your instructor knows where you are underwater at all times. No crowded groups. If a skill needs more practice, you get the time — not the time left over after 8 other students.
We teach both agencies at the same location. You choose which certification fits your future dive plans. We give you honest advice, not a push toward whichever we sell more of.
Proper briefing rooms, clean equipment rinsing stations, structured course schedule. The difference between a dive school and a beach shack matters when you are doing a multi-day certification course.
PADI eLearning for the Enriched Air course can be started immediately after booking. Complete the 5 knowledge sections on your phone or laptop before arriving in Goa — then Day 1 goes straight to gas analysis training and your Nitrox dives. No wasted time on theory you could have done at home.
