Catalina Nitrox - Specialty Course -including Two Dives is a hands-on, one-day nitrox training offered in Avalon, California. Designed for divers who want safer, longer bottom times and the confidence to manage enriched air, the course pairs shore-based classroom and equipment work with real dives in Catalina’s clear, cool water. Avalon’s nearshore environment is defined by sweeping kelp forests, exposed rocky reefs and boulder gardens where Garibaldi, kelp bass and other temperate species congregate; learning nitrox here means practicing on the same ecosystems that make Catalina iconic.
The program gives students a choice: a dry class-intensive option focused on analyzing gas mixes, setting dive computers, and logging procedures, or a full practical package that includes two dives using nitrox cylinders. Both choices include review of gas analysis, computer setup, and completion of Nitrox logs, and both are intentionally small—classes are limited to four students to maximize instructor feedback during pre-dive briefings and in-water practice.
What sets this offering apart is its locality and format: shore-based dives launched from Avalon make logistics straightforward—no boat transfers required—and the small group size means instructors can walk you through oxygen analyzer checks, partial pressure calculations, and real-time computer adjustments until you’re comfortable. The curriculum is succinct but thorough: equipment setup, gas analysis, conservative planning limits, and paperwork that leaves you ready to log nitrox dives on return trips to California or beyond.
Avalon’s underwater topography includes kelp canopies (Macrocystis pyrifera) that filter sunlight into bands of green and gold, rocky ledges that channel currents, and swim-throughs where visibility can sharpen on calm days. Expect to see Garibaldi, kelp bass, and occasional rays; seasonal visitors may include juvenile leopard sharks in the shallows. Historically, Catalina has long supported fishing and recreation, and today the island’s marine zoning and dive culture protect dive sites while offering exceptional classroom-to-water teaching opportunities.
Practical notes: bring a bathingsuit, towel, light jacket and your certification card if you plan a guided dive. Ferry travel and accommodations are not included. Students must complete standard medical and liability forms and be fluent in English for safety briefings. For divers seeking a compact, applied nitrox experience among one of southern California’s richest kelp systems, this course in Avalon is a smart, efficient step toward safer, longer dives.
Classes run year-round depending on weather and ferry schedules, and instructors tailor briefings to local tidal patterns. Because the sessions are shore-based they suit travelers staying in Avalon who want minimal gear transfers; students should verify ferry times and arrive with completed medical paperwork to streamline check-in. Choose the dry classroom option or the two-dive practical track—either way expect patient coaching, solid safety checks, and a clear path to adding Nitrox to your dive toolkit today.
