Technical Diving International

Formed in 1994. TDI is similar in content and make-up to IANTD but is considered to be the largest specialised training agency with over 10,000 instructors ready to teach the ways of technical diving.

In 1999 a sister company, Scuba Diving International was launched. This branch of TDI caters to the recreational diving as opposed to the technical aspects of TDI.
