Course overview

Extend your bottom time and shorten surface intervals with the SSI Enriched Air Nitrox specialty out of Puerto Ayora on Santa Cruz Island. Nitrox is a real advantage in the Galapagos, where repetitive dives on deep, current-swept sites like Gordon Rocks and Cousins Rock benefit from longer no-decompression limits. You earn the SSI Enriched Air Nitrox certification on completion.

What you’ll learn

• Understand how enriched air affects no-decompression limits
• Analyse cylinder oxygen content and calculate maximum operating depth
• Plan nitrox dives with a nitrox-capable computer or tables
• Track oxygen exposure across repetitive dives
• Handle, label and log nitrox cylinders safely

Prerequisites

• Minimum age 12 (Junior)
• SSI Open Water Diver or equivalent
• Diver medical clearance signed by a physician
