Technical Diving Courses

Technical Diving allows experienced divers to dive deeper, enter overhead environments such as a wreck or caves or dive for longer bottom times with specialized equipment after gaining expert training.
We provide expert training with our experienced and qualified in house training team who have been selected to represent Big Blue Tech. The training provided is designed to help create a smooth transition from your current diving level to your future goals.
Technical or deep dives are defined as dives deeper than the standard recreational limits of between 30-40m. This is due to the fact that breathing regular air while experiencing depths below 30m causes an increasing amount of impairment due to nitrogen narcosis.
Technical diving is also described as dives that are long enough to require mandatory decompression stops which can be performed using nitrox or pure oxygen. Decompression diving carries higher risks as it is no longer safe to make a direct ascent to the surface when underwater problems occur. That’s why obtaining the necessary technical training is essential before you consider this type of diving.
Taking technical diving even further is introducing the use of hypoxic breathing gas mixtures such as trimix, heliox and heliair. Breathing air at depths greater than 55m generally increases the risks of symptoms of oxygen toxicity. Adding helium to the air reduces both the percentage of Oxygen and Nitrogen in the breathing mix allowing deeper dive depths.
Inert gases, such as nitrogen and helium, are absorbed into body tissues when breathed under high pressure. These dissolved gases must be allowed to release gradually from body tissues to prevent decompression sickness or the bends, explaining the need for a decompression schedule at various stops of the ascent of a technical deep diver.
Technical diving involves significantly longer durations than recreational diving, therefore it is necessary to increase their supply of breathing gases by connecting multiple diving cylinders or by using a rebreather. Technical divers also carry reserve equipment and gases should they experience failure from their primary source, which is why you will see technical divers with much more equipment than recreational divers.
All our courses require dedication and focus, we expect all our students and divers to perform above the required standards outlined by the agencies we represent.
