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 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 worlds brightest scientists. That many of the victims of incorrect decompression 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 and how to survice it's more extreme effects.Vigilance urged when treating decompression illness with US Navy table 6A
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

Tips On Buying Used Scuba Diving Gear
Scuba diving is a wonderful sport. There is a whole world to explore beneath the water, but being properly outfitted is an expensive venture. can be cost prohibitive for some people to pursue, but there are options to buying all brand new scuba equipment and it’s worth your time to investigate them.

Spend time looking around; you will need to see what’s recommended, what’s available and how much items cost. This information will help you make educated choices in the used market.
If you learn where to look, used scuba gear is available in abundance. For many reasons, people choose or are forced to quit diving, leaving used (or barely used) and costly equipment taking up space in their closets or garages. It makes sense for them to try to unload their gear and for you to give purchasing it serious consideration.

I am based in spain (costa del sol)for most of my year, so I am hopeing to do a bit more diving there quite soon,...
good condition, safety-features intact and at a reasonable value.
As you continue to enjoy scuba diving, you will need to replace equipment. At that point, it might make sense for you to purchase new equipment to replace your old one. You will know that you are dedicated to the sport and will have a good understanding of features and any unique needs you may have. Of course, the advantage is that you will not need to buy everything, all at once.
