Tecdiving

All non commercial diving is categorized as recreational and within recreational diving there is sport and technical diving. Sport diving includes your open water certification, advanced scuba diver, and many other special course. Technical diving picks up where sport diving ends generally at nitrox (a breathing gas with oxygen levels greater than 21 percent).

Who is TDI?

TDI is the largest technical certification agency in the world. As one of the first agencies to provide training in mixed gas diving and rebreathers, TDI is seen as an innovator of new diving techniques and programs which previously were not available to the general public. Training with TDI has provided divers with the opportunity to see such wrecks as the Andrea Doria, Luisitania and the Prince of Wales. TDI divers have explored underwater caves in Spain, Australia and Mexico and assisted as support divers on world record freedives done in the Red Sea.

The term Technical Diving refers to a wide range of advanced level diving activities ranging from the overhead environment, to wreck, deep and/or mixed gas diving.

Red-Sea-Tecdiving aims to provide the highest level of technical diving training through our resident Technical Instructor. Sunsplash offers the full range of TDI courses and chooses the best course that suits your needs with a certification of high standards. Courses include basic nitrox, advanced nitrox, decompression procedures and trimix. Besides, we teach specific technical diving specialties such as twinset famillarisation, advanced buoyancy, DPV, decompression theory, deep rescue, oxygen admin and first aid. Most technical dives take place below 40m/130 ft where set decompression stops are required before surfacing. Nitrox became an accepted part of regular recreational diving and is now a part of many dive operations around the world.

If you are new to technical diving, then this page is designed to give you all the basic information you need to get.

First some of the most common questions:

 

 

What is technical diving?

Technical diving or tech diving is a form of scuba diving that exceeds the scope of recreational diving. Technical diving picks up where sport diving generally ends at nitrox (a breathing gas with oxygen levels greater than 21 percent). Decompression diving, using rich nitrox mixtures for decompression or the use of Trimix or Rebreathers are all likely to be classfied as technical diving. Technical divers require advanced training, extensive experience, specialized Equipment.

Will technical diving allow me to go deeper?

Yes. This what TDI stands for. The following steps are:

Techdiving Introduction

What is my first step into technical diving?

Answer: Nitrox is the first and popular step, but in case of not having any experience of technical diving, TDI Introduction to Technical Diving gives an overview of all aspects of technical diving. Twinset  Familliarisation is suitable for experienced divers who are used to a single cylinder. TDI Advanced Nitrox and Decompression Procedures course is suitable for those who have been diving with a twinset.

 

What is Nitrox ?

Nitrox is the name given to oxygen and nitrogen mix where the Fraction of oxygene is higher than normal (21%) content of air.

Why Nitrox?

To reduce the nitrogen content for longer dive in shallower water. It’s also for technical divers to optimize decompression dive by increasing the extraction process of dissolved inert gases in the diver’s body.

What is Trimix?

Trimix is a breathing gas where nitrogen and oxygene has been replaced by helium in order to reduce the effects of high partial pressure of both.
Diving with Trimix requires special procedures thorough understanding of the physics and physiolog.

Tips for Technical Divers:

  • Know your dive computer! You should be familiar with your computer, some have deco models so conservative and some not.
  • Slow ascents are a decompression technique.
  • Monitor ascent rate, your ascent is part of your total decompression profile.
  • Too fast is not good to slow will increase nitrogen gas loading during the deeper part.
  • Control your buoyancy, stay in control by dumping excess air during the ascent dive with one extra weight to counteract the positive buoyancy of an empty tank
  • Stay static.
  • Keep it simple, plan your dive.
  • Be comfortable under water by practicing the ability to maintain depth, manage your Gauges.
  • Never cut a decompression stop.
  • Assume the position tray to maintain a horizontal position during the stop.
  • Decompression stop should be a period of relaxation, mild exercise or not is bitter.
  • As a decompression diver on long hangs even warmer tropical water can edge you toward hypothermia, you will often need to be dressed more warmer as decompression diver
  • Risk extra gear results increased risk of over exertion to swimming resistance.
  • Stage, decompression Diving requires training and experience, only way to truly learn properly execute stage decompression dives.
  • Is it seak out quality training program from an experienced knowledge able instructor!
