What brands of dive equipment are there?
Major scuba diving brands such as Scubapro, Oceanic, Atomic, Cressi, Aqualung and Oceanpro provide top-notch scuba equipment crafted to guarantee optimal performance. In 1942, during the German occupation of France, Jacques-Yves Cousteau and Émile Gagnan designed the first successful and safe open-circuit scuba, a twin hose system known as the Aqua-Lung. Their system combined an improved demand regulator with high-pressure air tanks. This was patented in 1945.Jacques Cousteau and Emile Gagnan together invented the modern demand regulator used in underwater diving. Their invention allowed for the equipment known as the Aqualung, or self-contained underwater breathing apparatus (SCUBA), enabling safer and deeper dives.

What type of air do scuba divers use?
Many non-divers assume scuba tanks are filled with 100% oxygen. In reality, recreational divers typically use air (approximately 21% oxygen and 79% nitrogen) or Enriched Air Nitrox (ranging from 22% to 40% oxygen with the remainder filled in with nitrogen). Most SCUBA tanks last for about 20 years, as long as they’re properly cared for and inspected. If you have a steel tank that is properly maintained, it could last over 50 years.How Long Does a Scuba Tank Last? The duration of the air supply in a scuba tank depends on the factors mentioned above. Typically, an average scuba tank filled to 200 bar (3,000 psi) can last for 30 to 60 minutes at a depth of 10 to 18 metres (30 to 60 feet).Scuba tanks come in different sizes, ranging from very small 3 litre to large 15 litre (19 to 123 cubic feet tanks. The larger the tank, the more air it holds, and the longer you can stay underwater.The most common tank used in the United States for recreational diving is an 80 cubic foot aluminum tank with a working pressure of 3000 PSI. In Europe this tank would be referred to as a 10 liter tank with a working pressure of 200 BAR. Working pressure is important.
Do scuba divers buy their own tanks?
Many divers choose to rent their diving cylinders – at least at first. While buying your own means you will have to maintain it as well, owning your tank is useful if you want to dive far from the nearest rental shop. Even if your tank isn’t usable for diving, you may be able to remove and sell the valves, or sell the entire tank for scrap metal. When in doubt, bring it to a local dive shop, where the staff may know how to reuse it.
