International Diving Institute


IDI_logoWalk into Old Charleston Navy base where you’ll be greeting with sounds of ship horns, tall cranes, rusty pipes and diver splashes from dredging operations. The International Diving Institute (IDI) puts its students in the thick of it all, training them on commercial diving work with a Wet Tank triplex and mobile dive stations.

After receiving certification, divers have the opportunity to take an additional course which concentrates solely on underwater welding. This is the only dive school who certify under Lloyds Register and AWS WPQ D3.6:2010 Class B. Other courses include diving history, medical application, physics, safety and inspection, equipment maintenance, and research.


Tuition: $17,000
