How to produce clean, dry, divers breathing air that meets international standards
This article exposes the commonly held misconceptions about how compressor filtrations systems really work, and underlines the essential checks and maintenance necessary to produce clean dry divers breathing air - and save the dive operator a pile of money long-term in unnecessary scuba tank replacement costs.How to Avoid Isobaric Counter diffusion hits during trimix decompression
Isobaric Counter Diffusion triggered by breathing gas changes is predominantly a problem when carrying out Trimix dives that are deep enough and long enough to generate formal decompression stops that require the use of a hypoxic Trimix. An analysis program embodying these concepts to identify known unsafe ICD gas switching practices and unsafe decompression is made availableDecompression trends for extreme dive planning
Deriving the underlying laws and predictive mathematics for diving physiology, safe decompression, Oxygen toxicity tolerance, narcosis, and HPNS (High Pressure Nervous Syndrome) have challenged the minds of the world?s brightest scientists. That many of the victims of ?incorrect guestimation? fail to survive extreme decompression and be part of the ?observable phenomenon? database further hampers progress.
As a first topic in this series of articles we will take a more in depth look at decompression. Vigilance urged when treating decompression illness with US Navy table 6A
July 2005:- Satahip, Thailand 2005 was the location for the first hyperbaric technician course run by the British Diving and Diseases Research Centre (DDRC) - An organization set up to study the effects of pressure and provides hyperbaric chamber oxygen treatment facilities and medical training for divers, technicians, nurses and doctors worldwide.
During the course, the use of the various USN tables for the treatment of decompression illness and was studied. Technician trainees also had the opportunity to visit mono-place chambers at the Queen Sirikit Naval hospital to witness the use of hyperbaric oxygen to treat skin infections that did not respond well to other techniques.
For divers, the treatment of DCI generally results in the use of two US tables. Table-6 for type I DCI-pain only symptoms and skin rashes, and USN treatment table 6A for the treatment of type II DCI-Arterial Gas Embolism. Unfortunately, table 6A is also notorious amongst for causing DCI amongst attending medical personnel...World record deep dives made using new decompression technique
A new decompression diving technique based on the Combined Decompression Model CDM-18 that provides the knowledge base used by two previous world record breaking deep divers is made available to the diving public. A spreadsheet implementation of the CDM-18 model analyzes any dive profile and breathing gas combination for correct decompression methodology, clearly identifying any profile abnormality or breathing gas change that would likely cause DCS.First Internationally recognized Dive Technician Courses to be run in Thailand.

Before You Go Scuba Diving Make Sure You Have All Of The Basic Diving Equipment
Scuba diving is a fabulous sport to get involved in, but there is a down side - the equipment isn't cheap. If you're planning to do a lot of scuba diving, then you also need to allow for the costs of buying your own equipment.
When you're many meters under the surface of the ocean, you need to be

confident that you have the right gear and that it won't break down unexpectedly. So buying good quality equipment is important. Still, if you spend some time looking around, it's possible to still buy good gear at cheaper prices. You're going to need a few things, so if you manage to save some dollars, even if it's only on some of your gear, it all helps.
One piece of equipment you need is your mask. This is your window on the underwater world, so make sure it fits snugly and gives you a clear view. Over time a mask does tend to get scratched, so this is one piece of equipment you might not want to buy second hand. You also need a regulator, to help you breathe underwater. Basically, it takes the compressed air in your scuba tanks and reduces the pressure down to a level that is breathable. It only delivers air when you inhale, so that you don't waste the air in your tanks.
Another important piece of equipment is your buoyancy control device, or BCD. It's worn like a vest, and contains an expandable bladder that you inflate with air from your tank as you're diving. This is mandatory, because as you dive deeper, the water pressure increases. So unless you can increase your buoyancy at that point, you will start to sink like a stone.
Unless you're only diving in shallow, warm tropical waters, you're going to want a wet suit. This works efficiently to keep your body temperature at normal levels. The wet suit helps your body to deal with the increased water pressure at depths and also the colder temperatures. Some people are comfortable with a body suit, so that may suit you better. Either way, you end up with a skintight outfit that clings closely to your body.
Again, unless you're only diving in shallow water, you'll need a torch. You can pay

I found a Deep Outdoors weight pouch. Looks like it has been down all summer, if not longer. If anyone lost one or is in need of one, let me know. A little to high end of me ;- )
anything from $20 right through to thousands of dollars for an underwater torch, so do your research. Having a good torch, though, really makes it easier to see the beauty that's hidden beneath the water. The deeper you go, the less sunlight, and so the less color. It can be quite astounding to look at a bland, brown piece of coral deep under the ocean, only to highlight it with a torch and see it blaze with color.
Most scuba divers like to carry a knife. It's not an essential item, but can be used for digging or prying things. Remember to check whether it's okay to disturb the natural fauna where you're diving. A knife isn't meant to be used as a weapon underwater, unless it's absolutely necessary.
If you're not sure exactly what you need, head for your nearest scuba store and start asking questions. They will be able to assist you with choosing the right gear for your level of experience and the type of diving you're expecting to do.
