Scuba gear is the equipment used for scuba diving. It consists of a mask, snorkel, fins and buoyancy compensator device (BCD). The mask allows you to see underwater. The snorkel lets you breathe in the water with your mouth above the surface. Fins make it easier to swim without using your hands. The BCD inflates when underwater so that you float on top of it instead of sinking into it like an anchor (which would be bad).
A mask is a device that covers the eyes and nose. It has two lenses, which allow you to see underwater.
Scuba Masks are made of rubber or silicone. A strap holds the mask to your head while you swim, reducing the chance that it will be lost in rough seas or during a dive. Some masks have purge valves, which allow you to clear water out of your snorkel by blowing through them. Others have skirts attached around their lower edge that protect against contact with coral reefs—an important feature for those doing deep-sea diving and wreck exploration missions where these delicate organisms live!
A snorkel is a tube that goes in your mouth and has a valve that allows you to breathe in and out. Typically made of plastic or silicone, it’s often transparent and flexible so it can be rolled up when not in use.
Buoyancy Compensator Device (BCD)
A Buoyancy Compensator Device (BCD) is a device that allows you to change your buoyancy level underwater.
The BCD is usually made of rubberized neoprene and has several compartments for storing items like your oxygen tank, regulator, dive watch and other accessories. Most BCDs also have pockets for carrying your weight belt and diving knife if you’re doing deep diving or wreck diving.
The back inflation BCD consists of two separate air tanks: one in the front and one in the back which are connected by hoses that allow you to inflate these air tanks with air from your tank. This allows more freedom while swimming underwater because it gives more control over how much air pressure is released into either of those two tanks at any given time depending on how much weight you need to wear underwater (which would depend on depth).
Regulator is a device that delivers air from the scuba tank to the diver at a constant pressure. It’s probably the most important part of your gear, and it’s also one of the most expensive. The regulator controls air pressure going into your mouth, allowing you to breathe at regular intervals without having to worry about holding your breath or getting winded. If something goes wrong with your regulator, you could drown in minutes! That’s why regulators are often considered one of those “critical” scuba gear pieces that divers need to pay attention to when choosing equipment—and why it’s worth investing in a really high quality model if you want some peace of mind while diving in open waters.
Fins are the most important piece of equipment to have when diving. Without fins, you can’t swim underwater and therefore won’t be able to stay warm, keep safe or explore the ocean floor.
Fins provide propulsion while swimming. As such, they’re an essential part of scuba gear because they help you move through the water and reach your destination safely. The best fins for diving are made from strong materials like plastic or rubber; these materials are durable enough to last long periods of time without breaking down over time (while also being flexible enough so as not to cause injury).
Weight belt or integrated weights
You’ll probably want to put on a weight belt. This is a good idea if you are going below 30 feet, or if you are using heavy equipment. A weight belt can be clipped around your waist and allows for adjustable amounts of weight that distribute evenly around your body’s center of gravity.
If you choose to use integrated weights, these come with the BCD already attached and are ideal for recreational diving as well as spearfishing (although they cannot be used when scuba diving). Integrated BCDs have pockets for holding weights that are sewn into their design so there’s no need for an additional weight belt.
Don’t worry too much about how much weight you need—just remember that it’s important to wear enough! You’ll probably want something like 25 pounds on each side if you’re going down deep, but in general it’s best to start out with less than what feels comfortable because once in water pressure increases exponentially due to depth and temperature changes affect buoyancy control
Wetsuit or drysuit
Wetsuits are made of neoprene, a synthetic rubber material that insulates against cold. They are used only when the water temperature is above 60 degrees Fahrenheit (15 degrees Celsius).
A drysuit is made of Gore-Tex, a waterproof fabric that keeps you dry even in the most extreme conditions. A drysuit provides insulation while keeping you warm by trapping body heat inside the suit, rather than having it escape through the surface of your skin like it would in a wetsuit.
Scuba equipment are mandatory to go scubadiving.
Scuba equipment is mandatory to go scubadiving. The equipment can be divided into two categories: primary and secondary. Primary equipment are essential for the diver to live, such as air supply and buoyancy control. Secondary equipment include tools that enable divers to do specific tasks, such as cutting lines or carrying objects underwater.
The best way to know the gear is to try it out. Scuba diving equipment can be expensive and if you are not sure which one will work for your needs, it’s better to go with a cheaper option that still has all the features necessary for safe scuba diving.
