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.

Course details:

The TDI Decompression Procedures Course is scheduled over two days. Before the start of the course you will be sent the ‘TDI Decompression Procedures’ workbook which you will need to read as well as completing the knowledge reviews before we start the course. There is also a written exam and a kit orientation and a minimum of 4 dives

Here are some of the things you will be learning:

  • Decompression dive planning including:
    • Decompression gas choices
    • Tables vs. personal dive computers
    • Emergency and contingency planning (equipment failure, omitted decompression, etc.)
  • Decompression diving procedures
    • 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.)
  • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, and gas blending procedures




For all technical diving courses we would expect that you have your own equipment and that you are familiar with it. However, please let us know you are missing anything, you might be able to hire it from us or we could also place an order from one of our suppliers.

At MK Scuba Diving we like to keep the group as small as possible to ensure that you have plenty of time in the water and full attention from the instructor. The maximum students per group is four with the standard and one for the 1-2-1 option

We use mainly Stoney Cove – Sapcote Rd, Stoney Stanton, Leicester LE9 4DW. This is formal quarry which has great facilities and is ideal for dive training. They have a shop, gas filling station, changing rooms with showers and a pub where we usually go to do our debrief.

We also use Vobster and the NDAC so we can be flexible depending on where you are based.
