ANDI International (ANDI) is one of the world’s fastest growing diver training agencies. ANDI began by specializing in training programs for Enriched Air Nitrox ( SafeAir ) diving. As a natural evolution from SafeAir®, ANDI developed training programs for what has now become known as Technical diving and Closed Circuit Rebreather systems. To meet the demands of our international network of training facilities, in 1999 ANDI introduced a unique methodology for training entry-level divers with the ANDI Open Water Sport Diver program.
