## What are Scuba Diving Tanks Filled With?
Scuba diving tanks are filled with a variety of gases, depending on the type of diving being done and the depth of the dive. The most common gas used for scuba diving is compressed air, which is simply air that has been compressed to a high pressure. Compressed air is a good choice for recreational diving because it is relatively inexpensive and easy to find. However, it does have some limitations. Compressed air can only be used for dives up to a depth of about 130 feet (40 meters).
For dives deeper than 130 feet, a different gas mixture is required. The most common gas mixture used for deep diving is nitrox, which is a mixture of nitrogen and oxygen. Nitrox contains a higher percentage of oxygen than compressed air, which allows divers to stay underwater for longer periods of time. However, nitrox is also more expensive than compressed air and can be more difficult to find.
In addition to compressed air and nitrox, there are a number of other gases that can be used for scuba diving. These gases include helium, hydrogen, and neon. Helium is a very light gas that is used for deep dives and technical diving. Hydrogen is a very flammable gas that is used for very deep dives. Neon is a very rare gas that is used for very deep dives and technical diving.
The type of gas that is used for scuba diving is determined by the depth of the dive, the length of the dive, and the diver’s experience. It is important to choose the right gas for your dive to ensure your safety and the safety of your diving buddy.

### Factors to Consider When Choosing a Gas for Scuba Diving
The following are the factors that you should consider when choosing a gas for scuba diving:
The depth of the dive
The length of the dive
The diver’s experience
The cost of the gas
The availability of the gas
### Safety Considerations
It is important to follow all safety precautions when using scuba diving tanks. These precautions include:
Never dive alone.
Always check your equipment before each dive.
Be aware of the depth of the dive and the length of the dive.
Choose the right gas for your dive.
Monitor your air consumption throughout the dive.
Ascend slowly and safely.
By following these safety precautions, you can help to ensure your safety and the safety of your diving buddy.
