TDI – Technical Diving Courses

TDI is the largest technical certification agency in the world.  As one of the first agencies to provide training in mixed gas diving and rebreathers, TDI is an innovator of new diving techniques and programmes which previously were not available to the general public.   

TDI’s professionals are held to the highest standard to ensure quality training throughout the world.  This means that as a diver taking a TDI course, your instructor will have documented his experience and knowledge prior to achieving that rating.  As an instructor candidate taking a TDI course, your TDI instructor trainer will have gone through the paces to achieve the highest level of training that TDI offers. 

TDI is committed to offering the highest quality training supported by the latest materials with the most up to date information and techniques. These materials are updated as technology and equipment change. 

At Rubicon Diving we can provide the whole suite of TDI’s technical dive courses on Open Circuit (backmount and sidemount) and closed circuit rebreather. For information on the TDI courses that you are interested in click on the relevant banner below. Alternatively contact us directly at
