Scuba diving is the use of independent breathing equipment to stay underwater for long periods of time for recreational diving and professional diving. Generally the diver swims underwater, but walking and the use of diver propulsion vehicles is possible while breathing from scuba equipment. The word 'SCUBA' is an acronym for "Self Contained Underwater Breathing Apparatus", but it is grammatically acceptable to refer to 'scuba equipment' or 'scuba apparatus' in conversation.

Gauging DOT 3AL3000 SCUBA cylinder neck threads
In response to requests for clarification, from members in the Far East and Australasia, the following guidance is issued for SCUBA cylinders and valves that utilise the ¾" NPSM thread form.
ASSET recommends that technicians, involved in the assembly and maintenance of SCUBA cylinders and their valves, use the appropriate, calibrated, thread gauges as a means to ensure that they are both within tolerances and compatible with each other. Additionally, the technician should have received training in their use, as provided in the ASSET Dive Industry Technician’s and Cylinder Tester’s Courses and Manuals.
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 available

Tips When Choosing and Buying a Scuba Mask
Whether you are a recreational scuba diver or someone you scuba dive professionally, having the right scuba mask lets you dive much farther as well as provides you a much higher level of comfort while you explore the underwater world. The right scuba masks can give you hours of underwater exploration. Of course, when choosing among the various scuba masks available, you need to consider your other scuba equipment and make sure

the scuba mask you choose compliments them. You also need to consider the size of the scuba mask as well as its construction and lens.
When it comes to choosing a scuba mask, choose one that is durable, a scuba mask that you will be able to use throughout your scuba diving time. It does not matter if you only dive recreationally. You need to have the kind of scuba mask and other equipment that are durable and will provide you with a level of safety while you are in the water. Before you buy a scuba mask, check for features such as purge valves and nose pockets. You also need to check and consider other features such as field of vision and strap adjustment. The scuba mask you choose must be easy to use and one that fits you perfectly.
Perhaps the most important thing you need to consider when choosing a scuba mask is its construction.

You need a scuba mask that is durable and can resist wear and tear, particularly if you frequently scuba dive. Do some comparison shopping of the different brands of scuba masks. Compare the different features. Don't forget that customer reviews and opinions are valuable, too, and can play an important part to your decision as to which scuba mask to purchase. You are not limited to retailers and outlet stores either. You can also shop for scuba masks over the Internet. You may, in fact, find scuba masks that are high quality but at bargain and discount prices online. Like any other purchase, avoid purchasing a scuba mask on impulse. Take some time to shop around and look some more.

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 monoplace 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 personnelWorld 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 DCSFirst Internationally recognised Dive Technician Courses to be run in Thailand
