Technical and Cave DivingTechnical and Cave Diving are very advanced forms of diving that involve special training, equipment, and technique. For those with the willingness to learn and the commitment to acquire the best training and gear available, these form of diving can open up a whole new world for the advance diver to explore. Technical Diving involves dives to hundreds of feet breathing special blends of oxygen, helium, and nitrogen known as Trimix. These types of dives require the diver to perform decompression before ascending to the surface in order to slowly expel the inert gasses that accumulate in the body. If decompression is not performed correctly, bubbles of inert gas can form in the tissues and blood causing Decompression Sickness (DCS), more commonly known as The Bends. Cave Diving involves entering submerged caves. One of the hazards in caves is the fine silt that settles on the bottom. If this silt is disturbed by a diver untrained in special silt-avoidance techniques, it can rise into the water column and reduce visibility to zero rendering the diver blind. Swimming in a silt-out is like swimming in milk; no matter how bright one's diving light is, nothing, not even the diver's gauges will be visible. |
