Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.

Course details:

The TDI Advanced Nitrox Course  is scheduled over two days. Before the start of the course you will be sent the ‘TDI Advanced Nitrox’ workbook which you will need to read before we start the course as well as completing the knowledge reviews. There is also a written exam and a kit orientation. If the course is done as a stand alone, 4 dives with a minimum bottom time of 100 minutes are required.

Here are some the things you will be learning:

  • Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
  • Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
  • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen


Some of the skills you will complete in this course include:

  • Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
  • Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
  • Demonstrate the ability to manage free flow from primary regulator in controlled fashion, shut down cycle, and switch to back up regulator
  • Conduct appropriate safety stop while maintaining neutral buoyancy
  • Demonstrate the ability to share air with buddy as both recipient and donor in a controlled manner while maintaining position in the water column
  • Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
  • Demonstrate proper stress analysis with self and dive buddy




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.
