Aai Neptune Divers, Las Vegas

AAI Neptune Divers' instructors teach students of all levels various scuba-diving techniques, whether they want to become an instructor themselves, or simply want to obtain their diving certification. Open-water scuba-certification classes help the latter, giving students all the skills they need to travel to a submerged shipwreck or teach English to underprivileged merchildren. Rescue-diver classes explain how to rescue a fellow diver in the water, and they pair with CPR- and first-aid-certification courses. When they aren't teaching, the instructors lead dive trips out to Catalina.
