Are your no-decompression limits (NDLs) becoming restrictive during dives? Do you often find yourself needing to ascend earlier than desired? As recreational divers, planned decompression may not be a familiar concept.

The TDI Decompression Procedures Course is designed to equip you with the skills for planned staged decompression diving. With a maximum operating depth of 45 meters/150 feet, this course serves as your initial step beyond conventional recreational diving boundaries.

Combining the TDI Decompression Procedures Course with the TDI Advanced Nitrox course lays the groundwork for further advancement in technical diving.

Following completion of these two courses and gaining additional experience, you’ll be well-prepared to progress to higher technical levels.
