Learn to Scuba Dive


We offer certification through the Multinational Diving Educators Association (MDEA). MDEA has the industry's highest standards for education and service. The Multinational Diving Educators Association (MDEA) was organized in 1984 by a group of dive professionals. Head-quartered in Marathon, Florida, MDEA grew rapidly through leadership training programs and from interested members of other agencies who participated in crossover seminars. High standards were not compromised, and new ideas were developed as MDEA became recognized worldwide.
Since its inception in 1984, MDEA has a network of dive resorts worldwide that offer special discount packages to all MDEA certified divers. We also have a well-organized procedure for advanced and specialty classes that is unique. MDEA and all other nationally recognized SCUBA certification agencies in the U.S. must be accepted equally as defined by the Federal Trade Commission. This means you will have no issues with using your certification card wherever you dive around the world. If fact, presenting a MDEA issued certification at a resort can be considered a gold standard.
