## What Gases Are Used in Scuba Diving?
Scuba diving is a popular recreational activity that allows people to explore the underwater world. In order to breathe underwater, scuba divers use compressed gas that is stored in a scuba tank. The type of gas used in scuba diving depends on a number of factors, including the depth of the dive, the diver’s experience level, and the availability of gas.
### The Most Common Scuba Diving Gases
The most common gases used in scuba diving are:
* **Compressed air:** Compressed air is the most common gas used in scuba diving because it is relatively inexpensive and easy to obtain. It is also a good choice for beginners because it is less dense than other gases, which makes it easier to breathe.
* **Nitrox:** Nitrox is a mixture of oxygen and nitrogen that is used by experienced divers to extend their bottom time. Nitrox contains a higher percentage of oxygen than compressed air, which allows divers to stay underwater for longer periods of time without experiencing decompression sickness.
* **Trimix:** Trimix is a mixture of oxygen, nitrogen, and helium that is used by technical divers to dive to depths greater than 100 feet. Trimix is less dense than compressed air and nitrox, which makes it easier to breathe at great depths.
### Choosing the Right Gas for Your Dive
The type of gas you use for your dive will depend on a number of factors, including:
* **The depth of the dive:** The deeper you dive, the more pressure you will experience. This means that you will need to use a gas that is denser than compressed air, such as nitrox or trimix.
* **Your experience level:** If you are a beginner, it is best to use compressed air. As you gain more experience, you can start to use nitrox and trimix to extend your bottom time and dive to greater depths.
* **The availability of gas:** The type of gas that is available to you will depend on the dive shop you are using. Some dive shops only offer compressed air, while others offer nitrox and trimix.
### Safety Considerations
When using compressed gas for scuba diving, it is important to follow all safety precautions. These precautions include:
* **Always dive with a buddy:** Never dive alone. If you have a problem, your buddy can help you get to the surface safely.
* **Use a dive computer:** A dive computer can help you monitor your depth, dive time, and gas consumption. This information can help you stay safe and avoid decompression sickness.
* **Get proper training:** Before you start scuba diving, it is important to get proper training from a certified instructor. This training will teach you the basics of scuba diving, including how to use compressed gas safely.
### Conclusion
Scuba diving is a great way to explore the underwater world. By understanding the different types of gases that are used in scuba diving, you can choose the right gas for your dive and stay safe.
