What certifications do I need to take this course?

You must hold PADI Advanced Open Water (or equivalent) and complete the PADI e‑learning or manual before the hands-on session.

How long does the Enriched Air course take?

The practical portion is about three hours; e‑learning time varies, so allow additional online study time before your scheduled session.

Will you teach me how tanks are blended?

The course teaches oxygen analysis and safe handling, but full gas blending instruction is outside the standard Enriched Air Specialty scope.

Can I use nitrox on any recreational dive?

You can use nitrox within training limits and your computer’s settings; it’s excellent for repetitive dives but not a substitute for proper dive planning.

Is nitrox safer than air?

Nitrox reduces nitrogen uptake for many profiles, extending no-decompression time, but it introduces oxygen exposure limits that must be respected.

Are there age limits or medical requirements?

Check with Catalina Divers Supply for age or medical-clearance requirements; most operators require a self-declaration of fitness or physician clearance for certain conditions.

PADI Enriched Air Nitrox Course at Catalina Divers Supply

On the eastern shore of Santa Catalina Island, in the sheltered harbor town of Avalon, Enriched Air Specialty at Catalina Divers Supply unlocks longer bottom times and faster surface intervals. This three-hour PADI specialty brings nitrox—the oxygen-enriched mixes recreational divers use—to practice for divers who already hold Advanced Open Water certification. Meeting at Catalina Divers Supply in Avalon, you’ll work through oxygen exposure and gas planning, learn how to analyze tanks and set your computer, and apply theory to the kelp forests and rocky reefs that fringe Catalina Island. Catalina’s waters are famously clear and temperate for Southern California, with dense forests of Macrocystis pyrifera and reef structures of sandstone and limestone that harbor Garibaldi, kelp bass, and colorful invertebrates. The Enriched Air course matters here because the island’s repetitive two-tank schedules and frequent multi-dive days reward the extra no-decompression time nitrox provides. Instructors from Catalina Divers Supply combine short classroom sessions with hands-on cylinder analysis and pre-dive planning so you leave with both certification and practical plan for using nitrox safely on local dives. What makes this offering stand out is its context: it’s not a generic textbook course. Avalon’s dive sites—vertical walls, kelp canopies, and cooler thermoclines—make nitrox real. You’ll practice oxygen range limits using real tanks, learn weight adjustments for the buoyant kelp zone, and discuss conservative dive planning tailored to Catalina’s tide and swell patterns. Because the PADI Enriched Air Diver is a short, focused specialty, avid divers aiming for multiple daily dives or back-to-back boat trips will notice immediate benefits. Logistics are simple: prerequisites include Advanced Open Water and completion of the e‑learning or manual before your session; bring your basic scuba gear. The course is offered through Catalina Divers Supply in Avalon and can be teamed with dayboats to the Casino Point Marine Reserve or nearby sites for immediate application. That makes this both a training day and an invitation to keep exploring Catalina’s underwater gardens. Whether you’re working toward more ambitious itineraries around Southern California or want cleaner, longer dives around Avalon, the Enriched Air Specialty is efficient and practical—unlocking time underwater without complicating the dive. For divers who like to plan repeat dives around kelp formations and rocky reefs, nitrox converts ambition into attainable bottom time. The course’s short classroom modules emphasize safety, oxygen exposure limits, and gas blending basics, while instructors answer site-specific questions about currents, viz, and emergency procedures. Graduates return to shore with certificate, new confidence, and a plan for maximizing dive days. If your trip to Avalon includes multiple dives or island-hopping around the Channel, Enriched Air training pays off immediately—more minutes beneath the kelp canopy, more chances to spot Garibaldi.
