NAUI — National Association of Underwater Instructors

NAUI is a global scuba certification agency. It provides training standards for recreational and technical diving. You will find NAUI instructors in places like Koh Tao or Cebu because they maintain a large network of certified professionals. Their courses often focus on practical skills that prepare you for real ocean conditions. Some divers prefer this agency since their technical programs offer specific training for deep or decompression dives. I once saw a NAUI instructor in Komodo teach a student how to manage buoyancy during a 22 m dive in heavy surge. One common mistake is assuming all agencies teach the exact same skills. While many standards overlap, you should check if your specific resort accepts their digital certification before you fly. Always verify the instructor’s credentials in person.
