Know More About Technical Diving

Author: Max Walker

Within a decade, technical diving has moved from being the preserve of extremists to becoming a main stream, yet specialized, field. The rationale behind technical diving has been reached only after passing through a series of challenges and scrutiny in the past. In the late 1980s the International Association of Nitrox Technical Divers became the first specialized technical training centre, marking a revolution in diving.

For the recreational Scuba diver, the diving depth limit is 40m and the diver should surface directly in up an unrestricted course. However, technical divers enjoy unlimited diving depth and the diver may need to resurface along a more restricted route such as in technical cave diving.

Wreck diving also challenges the diver's ability to cope with unstable conditions and the maze-like corridors in a wreck. After a deep dive, the diver's body has absorbed a large amount of inert gas (mainly nitrogen). There is a life-threatening danger in surfacing without following a proper decompression process during the ascent.

Technical diving is a relatively risky activity; therefore, the training course follows stricter rules when admitting students. The instructor has the right to refuse non-suitable candidates onto courses such as technical cave diving and re-breather diving. Generally, students participating in basic technical diving courses should have at least two to three years of diving experience, perhaps even as certified recreational diving instructors.

The main difference between technical divers and recreational divers is not their experience or courage, but their mind set. Recreational divers are happy to swim over coral and fish, while technical divers are eager to test their limits. At a depth of 300 feet, the diver's personality, clear mind and technique are under massive stress. Even a minor mistake can lead to uncontrolled results in this environment. Therefore, psychological fitness is even more important than physical fitness for a technical diver.

How should you choose a technical diving training agent? There are about five international training centres in Hong Kong, including the founding agent IANTD and PADI. Several points should be considered when selecting a training centre: equipment availability and standard, insistence on reasonable and correct training procedures, the experience of the technical diving instructors, and the opinions of ex-students. Though cost could be another point to consider, the difference of a hundred or a thousand dollars is meaningless compared with the value of your life.

The course structure of a technical diving course is similar to a recreational one in that everyone starts from a basic level, even if you are a qualified instructor or experienced diver. The technical deep dive course comprises three different levels under the IANTD and PADI systems.

The basic course is named Advanced Nitrox Diver (IANTD) or Apprentice Tech Deep Diver (PADI). It teaches the student the benefits, hazards and proper procedures to dive to a 45m depth using high content oxygen for rapid decompression. This is deeper than the recreational diver's limit. It is important to strictly follow the time and safety stops procedures for surfacing, otherwise decompression sickness (the Bends) could result. If a diver spends 30mins at a depth of 45m, they will need an extra 40minutes for decompression.

After finishing the basic course, the student can move on to the Technical Nitrox Diver (IANTD) or Tec-Deep Diver (PADI). In this course, the student dives as deep as 55 meters with two oxygen-rich tanks (one is pure oxygen) for decompression. The 30-minute deep dive practice at 55m will necessitate another 50 mins for decompression. Apart from the deep dive practice, the student thoroughly studies the high pressure impact on the diver and psychological changes and works on improving posture and buoyancy control technique.

The final course is Trimix Diver. The diver uses a combination of low oxygen, low nitrogen and high helium gas mixtures for an 80m dive. This gas mix is essential for such a deep dive as ordinary pressurized air places negative impacts on the diver's body at depths of more than 55m. The 21% in air after 55m depth will cause the diver to conrulse and even lose consciousness - this is oxygen toxcity. Inappropriate usage of the trimix gases, however, will also cause problems; therefore, specialized training is a must.

All the technical diving courses include lectures, pool work and deep water practice. The ratio of instructor to student is much lower than in recreational diving courses in which one instructor handles 3 to 4 students and the ratio is even stricter for certain courses, to account for the more complicated nature of the course.

Technical Diving is still a risky activity, the technique and experience learnt from technical diving can feed back into recreational diving to improve the safety standard for the whole diving industry.

Thundering Horses and half Naked Chicks

By: Mark English
Does the sound of a high airflow, turbo injected V8 send shivers down your spine? Do you appreciate $30,000 paint jobs? What about $50,000 worth of stereo equipment? How do you feel about a semi that has been bushed and chromed? Does the sight of a bike built for speed put a smile on your face? How about hot, hot babes in clinging clothes and bikinis crawling all over these? Do you like to watch hot girls on the racetrack? What about insane crashes at high speeds and hilarious crashes when they are barely moving? Do you prefer Formula 1 to street racing? Or do you like drifting almost as much as off road? Do you like events where the drivers and the vehicle have to be able to handle all kinds of terrain or do you prefer watching them travel at 180+ mph as they travel in loops?

It doesn’t matter which one of these that you prefer, Motorsport Mad has a video for you. You can watch speed vids, driving expertise or lack of it and people watching the action with equal ease. There are videos of the big rig races, showing all six tires spin as they thunder across the track. There are go-kart races on dirt and paved tracks. They have the incredible speeds of Formula 1 and stock car. You can see some of the best footage on idiots trying to outrun the cops as well as footage of beefed up rides that do outrun the cops. They have burnouts from go-karts to motorcycles and crash test dummies trying out the newest cars. You can see the behind the scenes footage of rigged out movie cars as well as behind the scenes footage of shoots, cars, models, models and cars (occasionally, if you look hard enough, naked models and cars). You can see what comes from some guy shooting his hot girlfriend in a bikini bottom and white t-shirt, no bra, washing his hot rod. This can all be found at the unusual video sharing community, and it’s all free.

That’s right, all free. Somebody set up a site where anyone could load their footage, as long as it deals with some form of land transportation or hot babes, and where anybody could watch the footage at no cost to anyone. You may wonder how such a wealth of viewing opportunities can be free. After all most of these vids involving women you have to pay for. Not here, at Motorsport Mad, the viewers also provide the videos. Sure, sometimes exciting moments during the races are captured when a professional photographer is in charge of recording the action, but the news coverage doesn't usually spend much time on the hot chicks that frequent the racetracks and the car shows. Those videos come from viewers like yourself.

The site owners appreciate it if you visit their sponsors so that they can continue providing this at no charge, but they don’t demand it. So, go to www.motorsportmad.com and enjoy yourself for a bit. You will probably want some popcorn, candy, coke and either your boyfriend, girlfriend, husband, wife, friend with benefits or best of all, your car, and spend an evening watching the thundering horses.

Motorsport Mad has a video for you. They have the incredible speeds of Formula 1 and stock car.
