First, decide on your budget when purchasing a diving tank. There are many choices in terms of price, features, and types. The most expensive tanks may offer the best performance but they are not always the best for scuba diving. It is best to set a specific budget and stick to it. You will be able to avoid overspending or being distracted by other aspects. You may regret it later if you spend more than you can afford.
The shallow diving gas Nitrox, is called Nitrox.
A relatively new dive gas, Nitrox, is being used by recreational divers. It's used to raise the oxygen level in the water. It is more toxic than regular air at greater depths, so divers need to undergo specialty training before diving with nitrox. It is popular among recreational divers and shallow-depth divers as it is a good choice.
There are many advantages to diving with nitrox. The first is that you can breathe it for longer periods of time and experience less decompression sickness. This allows divers to spend less time in the water and to wait to get out. Decompression sickness is possible for all divers. If you're a beginner or planning to dive with others, make sure you consult the dive table regarding the recommended surface intervals.

Nitrox is safer than Helium. According to the American Dive Association (ADSA), nitrox diver have a lower likelihood of suffering from decompression sickness. Although nitrox is less likely to cause decompression sickness than other forms of gas, it has been linked with numerous fatalities. Nitrox has a higher level of inert and lower levels of oxygen. The DAN says it will encourage divers to test their tanks before diving, and to clearly mark their maximum operating depth.
Scuba tanks can be flooded with pure oxygen, which can lead to explosive or flammable situations.
Pure oxygen, which is dangerous when used in a tank for diving, must be handled with care. In extreme cases, pure oxygen may ignite and start a fire. Divers need to use special equipment in order to safely deal with it. To avoid an explosion, they must be able slowly open the valves. Proper preparation is also critical to the safety of the tank and filler.
Problems occur when the tank becomes too full or the oxygen levels fall below a safe limit. Because oxygen behaves different from air, compressed or nitrogen, there can be a high pressure in the tank. This can lead to an explosion if the oxygen enrichment equipment is not operating properly or is insufficiently protected. It is possible for a fire to start and it can be difficult to extinguish.
The high velocity that oxygen travels from the oxygen tank compounds the problem. This high velocity causes friction, which can ignite. Explosive or flammable situations can also be created by dead ends within the oxygen cylinder.

Before using scuba tanks oxygen, please be aware of the safety precautions
It is important to use the oxygen in your Scuba Tank safely and following the recommended guidelines. Before diving, make sure to inspect the pressure gauge. How long you can stay under water will depend on how much air is left in the tank. It is essential that you always surface with sufficient air. This means that you need to have at least 50 Bar of pressure or 500 PSI. Following the rule-of-thirds is one way to allocate air into the tank.
Another important safety precaution when using scuba tank oxygen is to avoid breathing while underwater. This is dangerous and can cause serious injury or even death. Lung over-expansion caused by oxygen in the air can result in air bubbles leaving the lungs. When this happens, oxygen-containing cells can burst and cause damage to the lungs.
