Decompression Procedures

Course Duration: 4 dives, 5 days


  • Be at least 18 years old (with parents consent up to 15 years old)
  • Advanced Open Water Certification and TDI Advanced Nitrox Diver Certification (or equivalent)
  • Show proof of 25 logged open water dives

This course examines the theory, methods and procedures of planned stage decompression diving.

This program is designed as a stand-alone course or it may be taught in conjunction with such TDI courses as Advanced Nitrox Course, Advanced Wreck Course, or Extended Range Course.

The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45m unless taught in conjunction with the Extended Range Course. The most common equipment requirements, gear set-up, and decompression techniques are presented. Students are permitted to utilize Enriched Air Nitrox mixes or oxygen for decompression provided the gas mix is within their current certification level.

The course is scheduled over three days. Prior to beginning the course you will be given the ‘TDI Decompression Procedures’ workbook. As with all our training we ask you to complete the knowledge reviews before you arrive for your academic presentation. There is also a written exam and a kit orientation.
