Scuba Network New Jersey, New York

Spanning the eastern shores of the U.S. from New York to Florida, Scuba Network’s staff has overseen thousands of completed scuba certifications throughout its eight locations. Group NAUI certification courses keep learning to dive simple with a three-step process that includes online academic training, pool sessions, and open-water dives with sharks that have had their teeth removed by a dentist. Staffers supplement dives with know-how on equipment, from masks and snorkels to underwater cameras.
