Is there an open-water dive included?

No. This listing describes the computer Nitrox specialty with online theory and an in-person skills session; actual dives are typically arranged separately.

How long does the in-person session take?

The practical, instructor-led meeting is about two hours after you complete the online modules.

Will I learn to analyze tank oxygen content?

Yes. Hands-on oxygen analyzer drills and tank labeling are core skills practiced in the session.

Are there age or medical restrictions?

Standard recreational diving medical considerations apply; if you have respiratory or cardiac issues consult a physician and disclose conditions to the instructor.

At 42 W 18th St on Manhattan's Flatiron district, SDI Computer Nitrox Diver condenses a signature recreational diving upgrade into a compact, urban-friendly course. Designed for certified open water divers, the SDI Nitrox program teaches you to analyze and plan dives using Enriched Air Nitrox (EANx) and a dive computer, letting you lengthen no-decompression limits and reduce nitrogen exposure with smarter gas management. In a two-hour in-person session following required online theory, instructors walk through oxygen exposure limits, partial pressure calculations, and routine use of an analyzer and dive computer. The classroom is practical: benches and gear stations convert rapidly from lecture to hands-on work, where students practice labeling tanks, setting computers to EANx mixes, and verifying oxygen content. Key features of the experience include the oxygen analyzer drill, dive computer programming, logbook reviews, and personalized gas planning. The broader backdrop is unmistakably New York - the training sits two blocks from the Hudson River estuary and New York Harbor, where seasonal shore and boat dives send local divers out to wrecks and artificial reefs. This course is especially useful here because urban centers like New York are launch points for day boats, night dives, and seasonal trips to Long Island and New Jersey coastal sites; learning to use Nitrox at a city facility means you hit the water prepared. Nitrox is a practical tool in the Northeast's often-cold, brief bottom-time conditions, extending safe bottom time for repetitive dives and aiding photographers and technical divers who want longer working windows. What makes this offering stand out is the emphasis on the modern dive computer as a planning tool, not just a gauge. Instructors pair computer settings with real measurables - oxygen analysis, depth planning, and conservative programming - so divers leave with checklist habits they use immediately on charters. The location's proximity to transit, gear shops, and waterfront piers makes it easy to schedule follow-up dives. A short cultural note: New York's harbor has hosted recreational divers for decades, evolving from club-driven exploration to professional charters and shop-run training. Practicing responsible gas blending and using proper labeling helps protect a crowded urban diving scene and supports safe access to local reefs and wrecks. If you want longer no-decompression times and a better use of your dive computer, this compact course is an efficient, practical upgrade before your next charter out of the city. Classes run small to allow hands-on analyzer time; bring your certification card and logbook. The in-person meet-up happens at 42 W 18th St, 3rd floor, New York, NY 10011, USA, and online modules must be completed beforehand. For exact scheduling and to reserve a seat, follow the booking link; many divers pair this specialty with a charter.
