Technical diving was brought to Europe at the beginning of the '90. Before that groups of enthusiasts in America were trying to find a safe way to dive deeper and longer, approaching depths that were only reserved for commercial divers.
Today we can say that technical diving is diving beyond the limits of recreational diving. These dives are not necessarily weary deep but can be for a prolonged period of time, making a decompression mandatory.
Because the nature can't be fooled, wearies gas mixes, depending on the depth are used.
This all makes specially equipment, training and education necessary.
The only guarantee for sucesfuly ending such operations are, the best equipment money can buy, the best education and the best mental and physical training.

IANTD was the first organization that made standards for technical diving and this was one of the reasons that our instructors decided to enable themselves to teach according to this standards.

Technical diving is and will stay a elite sport. The easiest way to become a part of it is to get a good education. TAKE A COURSE DON'T EXPERIMENT, YOUR LIFE DEPEND ON IT.
