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.

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.

Scuba Diving: A Brief Historical Background
Did you know that man has been diving for centuries, long before any breathing apparatus for diving has been developed or invented? Man dove the deep by holding their breath. Proof of this are the many ancient artifacts that were of undersea origin found on land as well as ancient drawings depicting divers.
In ancient Greece, many engaged in sponge hunting and military exploits

that involved diving deep under the water and holding their breath. According to Herodotus, a Greek historian who lived in fifth century B.C., the Persian King Xerxes I took the Greek Scyllis prisoner aboard his ship. Upon discovering that King Xerxes I was going to launch an attack on a Greek flotilla, Scyllis got hold of a knife and escaped by jumping into the sea. Because he could not be found, the Persians assumed that Scyllis drowned. However, Scyllis was alive; he swam to the surface at night and used a hollow reed as snorkel to breathe during the day when he remained under the surface. This allowed him to become undetected and enabled him to swim nine miles to join the Greeks who were moored off Cape Artemisium.
Today, you can explore the underwater world without holding your breath or having to learn this particular skill. There are various scuba diving equipment available that can help you breathe underwater. Scuba diving is also not just for professional divers. Scuba diving is now also for people who are seeking new adventures and leisure activities. Many seaside destinations have scuba diving outfits and rentals. In addition, these places may also offer basic or intensive scuba diving lessons and training.
Holiday divers usually flock to tropical and sub-tropical destinations where they can explore various underwater worlds. They are commonly referred to as recreational divers in that they tend to dive only when they are on vacation. Their recreational diving depths are between 30 and 40 meters. Then there are destinations whose main underwater

attractions are deep wreck dives. These destinations usually attract technical divers whose scuba diving equipment and gear are different from the equipment and gear used by recreational divers. Technical divers also undergo more specialized scuba diving training than recreational divers.
Nowadays, it seems like there are two types of recreational divers -- the regular recreational divers and the leisure divers. Regular recreation divers are those scuba divers who scuba dive in their home communities frequently. Leisure divers, on the other hand, are those scuba divers who dive occasionally, usually when they are vacationing abroad. Leisure divers are regarded by the diving community as comparatively inexperienced. They are encouraged to dive more regularly in their home communities so they can build scuba diving experience while supporting the local diving scene. It should be noted, though, that the accident and death rate in recreational diving is very low, which leads many to think that the current scuba diving training requirements are sufficient.
