main tekkie picture

TDI Instructor David Carson has experience teaching technical programs in mixed gas and overhead environments. David puts special emphasis on concise, accurate dive planning and decisive responses to in-water contingencies. His focus on proven techniques and clean, simple equipment configuration will develop a safe and efficient diver with the right attitude towards self-awareness and team-oriented diving.

Whether your interests lie in nitrox, rebreathers, mixed gas or any of the many other programs that

TDI offers, you can be assured that you will be participating in training that offers you the "cutting edge" of diving technology.

We have a fully air conditioned gas blending station on site for Nitrox and Trimix. Our Oxygen is highest quality medical grade. We blend Nitrox to any mix, making sure that you are getting the best optimal ppo2 of 1.4.

We offer you the correct Nitrox mix you require according to your dive – not the dive according to the Nitrox.

We can supply up to 100%.

This is the advantage of completing a Technical TDI Course:

Example 1:Max Depth 18m would require Nitrox 50%

Example 2:Max Depth 30m would require Nitrox 35%

Example 3:Max Depth 40m would require Nitrox 28%

Nitrox will only be supplied to qualified divers – if you are not qualified you can do your Basic TDI Nitrox course in ONE day.

We cater for rebreather divers wishing to bring their own units to Tenerife and we run CCR Courses

The new boat is fitted with all the necessary safety equipment to carry out technical diving.
