Have you ever experienced the underwater world? In this book it will show you the equipment used to do so. Prepare to be amazed because this book gets you one step closer to reaching that goal.
Scuba tanks are very strong tanks that hold the air you use to breath. They hook to your buoyancy control device and your regulator, which you will learn about later. There are smaller tanks that you use in case you run out of air, so you have enough air to reach the surface.
Regulators involve the first and the second stage. The first stage lowers the air pressure to breathing level. From there the first stage the air then transfers to the second stage, where it is then ready to breathe. Regulators have mechanisms that allow air to come through when you breathe in, and release the air you breathed into the water when you exhale.
Buoyancy control device:
Buoyancy control devices are for safety reasons and to protect the underwater environment. Buoyancy control devices are like vests that hold air in them. You use low pressure inflators to add or release air. You can also orally inflate buoyancy control devices, which means to use air from your mouth to inflate it. The reason that these can be used for safety reasons is because if something were to go wrong, you can just use the low pressure inflator or orally inflate it and you will float directly up to the surface. It also enables you to have neutral buoyancy. Neutral buoyancy helps you stay off the underwater floor and protect aquatic life.
Masks are a key part of scuba diving because they allow you to be able to see underwater. Your eyes can’t see very well underwater and what a mask does is create an air pocket between your eyes and the water. Also the deeper you go the more water pressure there becomes. The air in your mask gets compressed and eventually you need to add air to your mask. To do this you blow air into your mask through your nose. This is why you need a mask that covers your nose.
Fins are used to propel you through the water and make it easier to swim. There are two types of fins and they are split fins and regular fins. Split fins have a split down the middle that make it easier to swim and since there are splits in each fin it makes it feel like there are four fins propelling you instead of two.
Buoyancy: power to float or sink in a fluid
Neutral buoyancy: to neither sink or float in a liquid
