Decompression Procedures

Do you find your no-decompression limits (NDLs) a limiting factor to dives time? Your  TDI Decompression Procedures Course will prepare 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.

What does the course consist of?
During your Decompression Procedures Course you will focus on:

Theory:
  • Decompression gas choices
  • Tables vs. personal dive computers
  • Emergency and contingency planning (equipment failure, omitted decompression, etc.)
Practical:

    • Equipment selection
    • Pre-dive checks and drills
    • Stress analysis and mitigation
    • Following a decompression schedule
    • Gas switching
    • Team awareness and communication
    • SMB/lift bag deployment
  • Proper trim, buoyancy and finning techniques
  • Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, etc.)

What can I do after this course?
Things to do after you qualify: Go on Dive Trips
At Wraysbury Dive Centre we organise dive trips both at home in the UK and abroad.   Trips are organised for all levels of diver.  Just keep an eye on our trips page here and on our facebook page for upcoming events
Things to do after you qualify: Buy Dive Kit
We would always recommend that you purchase your dive equipment from a dive shop rather than shopping online (and its not just because we have a dive shop on site).  Buying in person allows you to try things on so that you get the right fit, get the right advice and kit for the type of diving that you intend to do and benefit from the experience of those that actually go diving.  You may also end up with a better deal than you imagined.
