TECHNICAL DIVING THAILAND

If you have never heard of Technical Diving or if you think that Technical Diving has something to do with Commercial diving than we are more than willing to explain to you what Technical Diving really is.

TECHNICAL TEC DIVING THAILAND COURSES IN PHUKET

There is some level of professional disagreement as to what the term Technical Diving should encompass. It was not that many years ago that Nitrox diving (i.e using a gas mix containing more oxygen than standard air) was considered “technical”; many skeptics believed that it was high maintenance and held no place in recreational diving.

However today Nitrox is not normally considered technical. Some believe that technical diving is any type of SCUBA diving that is considered higher risk than conventional recreational diving. Additionally, many who agree on most broad definitions of technical diving may disagree on the precise boundaries between technical and recreational diving.

Here is a little overview of the differences between Rec and Tec (10 meters is 33.3 feet):

TECHNICAL DIVING:

Recreational divers are trained (with Deep Specialty rating) to a max depth of 40m, the worldwide maximum depth for non decompression diving. During Tec training however, this depth limit is increased based on the level of training being undertaken. The depth-based definition is derived from the fact that breathing regular air while experiencing pressures causes a progressively increasing amount of impairment due to Nitrogen Narcosis, a narcotic effect on the body caused by increased pressures of nitrogen within the divers tissues. This usually becomes apparent to the diver at depths of 30 meters (100 ft) or greater. Increasing pressure at depth also increases the risk of oxygen toxicity based on the partial pressure of oxygen in the breathing mixture. For this reason technical diving often includes the use of breathing mixtures other than air.

DECOMPRESSION DIVING:

While the Rec diver is solely trained for No-Decompression Diving (staying within limits governed by Recreational dive tables), the Tec diver will be trained to move outside of these limits. The purpose of decompression diving is to allow the diver to stay longer at depth and compensate for this by making predetermined stops during ascent to the surface. This allows inert gasses in the body tissues (primarily Nitrogen) to be released slowly, thereby avoiding complications from Decompression Sickness, or The bends.

MIXED GAS DIVING/GAS SWITCHING:

Rec divers use compressed air and some basic Nitrox mixes only. Tec divers also use these gasses, but they may also use Nitrox with an oxygen content higher than the Rec limit of 40%. After further mixed gas training they are also able to use additional gas mixes containing other gasses such as Helium or even Hydrogen, creating options such as Trimix, Heliox, Heliair and Hydrox. This type of diving requires extensive dive planning and gas management, but allows the diver to manage their gas intake before they even submerge. Gas switching means exactly that: the ability of a diver to switch between different breathing gases underwater. In Rec diving only a single gas is used, while for Tec diving the diver may switch between gasses to accelerate decompression (shorten time required during stops) and/or “travel mixes” to permit descent carrying hypoxic gas mixes, or gasses with an oxygen content too low to sustain life (e.g. 16% at the surface.)
