On the south shore of Santa Catalina Island lies Cozumel Nitrox - Two Dives, a hands-on nitrox review and two-dive option run from Avalon, California, United States. Designed for divers who want to move beyond air and get comfortable with enriched air nitrox systems, this compact one-day experience blends classroom clarity with shore-based dives in small groups (up to four students) to focus on computer setup, gas analysis, and logging technique. Choose between a dry classroom review that walks through procedures and computer settings, or the full two-dive option that puts theory into practice underwater. Both formats include instruction on analyzing tanks, setting oxygen percentages on dive computers, and completing official nitrox logs so your entries stay accurate and accepted by agencies. The logistics are straightforward: shore entries mean shorter surface intervals and less motion for students who prefer to avoid boat travel, while on-water feedback from your instructor helps dial in buoyancy, air consumption, and decompression planning for enriched air profiles. Local waters around Avalon are known for giant kelp forests, rocky reefs, and resident fish like Garibaldi and bass—features that make navigation and depth control useful skills to practice. Expect brief classroom sessions, pre-dive checks, two shore dives (for the dive option), and focused post-dive debriefs documenting how you set your computer and log each dive. The operation requires that candidates complete any agency e-learning beforehand and bring certification cards if the dives are guided. Bring a light jacket, sunscreen, swimwear, towel, and your certification card; drinking water is provided, but boat tickets, meals, and accommodations are not included. Small class sizes mean more hands-on time with oxygen analyzers and personalized coaching on how to avoid common nitrox mistakes like forgetting to set the computer or miscalculating maximum operating depth. Safety is paramount: students must understand English for briefings and complete medical and liability paperwork; instructors reserve the right to cancel dives for anyone who appears impaired. For divers visiting Catalina from the mainland, this course is a quick skill climb that improves bottom time options and comfort, and it’s an efficient way to add nitrox competence to an existing card. Whether you’re returning to shore after a season away or preparing for deeper multi-day trips, this focused course makes nitrox approachable, practical, and immediately useful in the kelp-lined coves of Avalon. Scubawomen’s local instructors combine island-specific teaching—tight current management, kelp navigation, and reef conservation practices—with a focused syllabus, creating a learning loop that graduates divers ready to explore Catalina’s kelp forests responsibly; that blend of technical coaching, small groups, and shore-entry convenience makes Cozumel Nitrox - Two Dives a standout skill-builder for visiting and resident divers alike, and supports local marine stewardship efforts.
