TDI Decompression Procedures

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught.  The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits.
The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

The certified Advanced Diver looking to expand their knowledge of decompression theory and diving techniques

The certified Advanced Diver who is interested in extending their bottom time

The certified Advanced Diver who has interest in moving forward with technical diving education

Course prerequisites:

Minimum age 18
