Extended Range TDI Training: Deep dive with decompression

The Tek Extended Range TDI Training in Marseille trains you to approach the deeper dives to the air up to 60m with safety and comfort.

Trimix Diving TrainingDiving TEK Marseille

With the Extended Range TDI course, you will learn to dive with a more sophisticated configuration: twin tank for more autonomy, Tek stab for more volume, blocks of Deco for more security!

You will learn how to use the most suitable deco blocks for your dive, as well as use the multi-gas computer if you are equipped with it and build a run-time with specific software like V-Planner to optimize your decompression.

You will learn the rule of What if? What if?

Gas loss background – loss of Deco gas – loss of decompression means – loss of mask – loss of means of buoyancy – loss of binomial...

This demanding training is reserved for Level 3 divers who want to start new challenges! A great prerequisite for the next step: diving trimix!

Your Extended Range TDI training Program

Dive Planning

1. Demonstrate fluency in sign communication (basic and intermediate signs)

2. Selection and preparation of material for diving with high duration decompression.

3. Perform team exercises for the deployment of a lift parachute and the change of gas.

4. Rescue exercises to partner.

5. Unconscious diver assistance exercises.

6. Properly analyze the mixtures of each of its bottles

7. Properly plan and analyze dives by determining

A. The limits of depth and duration according to his personal abilities, the conditions of dives and his personal limits of consumption and his teammates,

B. The depth and duration limits of O2 at the intended levels with the mixtures actually used, in order to never exceed the individual and cumulative limits,

C. The nitrogen-associated limits at the intended depths with the mixtures actually used.

Exercises before diving:

Carry out different checks before each dive:

· Gestures air failure + control opening bottle

· Crew control equipment

· Gas control

· Orientation Planning

· Diving and Deco planning

Stress and relaxation analysis

Similarity of gases within the dive

Diving skills

1. Demonstrate buoyancy control: ability to maintain a stable position without movement

2. Demonstrate satisfactory consideration of the binomial and other members of the dive through communication, proximity and certain dives.

3. Demonstrate the ability to manage two ponys (either 2 deco gases or a Deco gas and blend pony background) including knowing how to remove and deliver a Deco pony while maintaining the immersion level.

4. Demonstrate the ability to confirm gas changes in depth with the crew member and dive members.

5. Demonstrate the ability to send the parachute from a certain depth and use it as a means of rescue buoyancy.

6. Demonstrate the ability to perform a bit-sharing lift with one diver without a mask.

7. Execute an emergency decompression simulating a loss of the Deco pony.

8. Remove and replace the mask (using the emergency mask)

9. Demonstrate the ability to tow an unconscious diver on the surface and immerse (30 meters)

10. Execute a 15-metre deep apnea.

11. Execute the dive as planned.

12. Demonstrate procedures for changing and isolating a defective regulator. This must be done during a dive at less than 40 meters.

13. Demonstrate approriées orientation techniques for diving.

14. During two dives, carry out its ascent after having correctly deployed the parachute/surface buoy mounted on the reel, then perform the decompression in the planned level.

15. During one of the dives, tow 10 m in depth a diver simulating unconsciousness and simulating a technique of recovery
