Technical Diving
What is it?
Technical diving is a term used to describe a form of scuba diving that exceeds the
scope of recreational diving with regards to depth and immersion time. The divers
require advanced training and specialised equipment. Also, they often breathe special
gas mixes other than air and/or nitrox.
In normal recreational scuba dives, the recommended depth limit is 40 metres. However,
technical divers can often be found in the 60 to 100 metre depth range.
These technical dives must be pre planned before the dive so the divers can use the
optimum breathing mix for their depth and planned dive time to reduce the length
of their decompression stops. Dives like this always require one or more decompression
stops, where the divers will often switch breathing gases to accelerate their decompression.
Mixed Gases for Technical Diving
Any Dive during which the diver breathes a breathing gas other than Nitrox or Compressed
Air, is known as a mixed gas dive. These mixed gases (such as Heliox and Trimix)
are used as a means to reduce the narcotic effect of Nitrogen and the increased risk
of oxygen toxicity when diving air at depth.. For instance, the Helium in Trimix
has no narcotic effect at depth and is a lower density gas than nitrogen, which makes
it easier to breathe. However, using trimix requires training. The dives themselves
require detailed planning and sophisticated equipment. It never hurts to have external
support from those who have the proper experience and knowledge with the facilities
to properly mix the gases and advise on the dive plan.
Deep Inspirations is affiliated with Scuba Tech Diving Centre in Cyprus for all the
Technical diving and training courses offered.
Scuba Tech is the only dedicated technical diving centre in Eastern Cyprus and
is a registered BSAC and TDI Technical centre.
Together with Scuba Tech, we can offer a range of Technical diving courses from Advanced
nitrox to Trimix. Equally, we can offer a number of “dry” courses (no diving involved)
including gas blender (nitrox and trimix) and life support systems service technicians.

Rebreathers are now being hailed as the future of diving. In the simplest of terms,
a rebreather recycles the air that the diver breathes by removing Carbon Dioxide
from exhaled breath, then adding Oxygen so the mix can be breathed again or ‘re-breathed’,
thereby eliminating the age old problem of scuba diving... A limited gas supply.
Rebreathers also have decompression benefits etc. For more information, follow the
rebreather link above.
