Buoyancy Control System Components

Buoyancy Control is one of the most important skills that divers need to have. 

Neutral Buoyancy is a state of mind underwater. However, it might come naturally to all of us. It can take a while for some of us to master.  

Most of the time, buoyancy is about proper weighing, and divers often overweight themselves.  

Basically, it becomes more difficult for them to maintain their neutral buoyancy throughout their entire dive because they overweight themselves. 

With that said, one bit of important scuba gear is your BC for scuba diving. It lets us have a decent and comfortable dive underwater.  

Come to think of it, if you are trying to stay neutrally buoyant without a buoyancy compensator. It doesn’t make for a pretty picture, isn’t that right?  

However, on the off chance that you are new to diving or are considering buying a scuba diving BC, a comprehension of the considerable number of parts that involve a scuba BC would be useful.  

Beneath, we clarify and name the pieces of a scuba diving BC, including inflator and deflator hoses, dump valves, straps, and more. 

Utilizing a bit of scuba gear is generally simpler on the off chance that you comprehend what it is about.  

So how about we get acquainted with BC scuba diving? 

In this article, you will learn about the buoyancy control system components. So, without further ado, let’s get started! 

Buoyancy Control System Components

What are the Buoyancy Control System Components? 

Buoyancy Control System Components or the Buoyancy Control Device parts are the ff; 

  • Buoyancy Compensator 
  • Inflation Device 
  • Weight belt or BC weight pockets 

The Buoyancy Compensator, also known as the ‘’Buoyancy Control Device’’ is a bit of diving gear with an inflatable bladder that divers wear to set up neutral buoyancy underwater and positive buoyancy at the surface, when required. 

Buoyancy Control System Components


Many of us are aware that scuba diving is involved in a wide range of bits of scuba gear and equipment. Each of them provides good purposes in the sport. If there are chances that you are already prepared to put resources into another Buoyancy control gadget (BCD), at that point, there are a couple of things that you should investigate before you do only that.  

Knowing how a BCD function is one of the essential things you should know before you invest. Nevertheless, preferring is that all parts of a scuba BCD serve a limit; do you know what all of their abilities are?  

In case you don’t, this is something different you should make sense of how to help make your BCD hopping a by a wide margin prevalent experience for you.  

As a diver realizing lightness control framework segments/BCD parts, where they are, and how to utilize them is fundamental information, all things considered with all pieces of scuba gear. 

The BCD is the thing that gives you balance underwater and at the surface, so dealing with them appropriately additionally implies better BCD diving. 

Buoyancy Control System Components

Components of a Scuba BCD 

Underneath, we have gathered a direct survey of the particular basic BCD parts of a scuba BCD. This will support you while picking the best contraption for your choice of BCD diving.  

If you certainly understand your Buoyancy Control System fragments, it’s continually a keen idea to search for quick memory practice on all the different limits.  

Remember, different sorts of BC scuba may have additional features. Below we have endeavored to cover the essentials of Buoyancy Control System parts that can be found on most. 

Air Bladder 

This is actually what it seems like, a bladder that holds air and, basically, the explanation present-day scuba bc’s existed. You can swell or flatten the bladder to assist you with remaining neutral buoyancy.  

The air bladder in the photograph to the correct starts in the back and folds over your midsection. Likewise, there are “wing” style BC’s, the place the air bladder is situated in the back and doesn’t fold over.  

The most significant part of a scuba BCD is the air bladder. The air bladder resembles a sack that holds air. How much air is inside the air bladder impacts how light you are? As it were, regardless of whether you drift up or sink further down relies upon how a lot of air is inside the bladder. Figure out how to ace your lightness here.  

Expanding the air inside your bladder makes a more prominent upward power, so you ascend or glide. Diminishing the air inside your bladder expands the descending power, which makes you sink. The exact spot of the air bladder relies upon the sort of gadget. The air bladders are normally situated around the abdomen of the diver or on their back. 

Power Inflator and Manual Inflator 

You increment the measure of air inside the air bladder utilizing the inflator. 

There are two kinds of inflators, a power inflator and a manual inflator. Both achieve something very similar placing air into your scuba diving BC.  

The power inflator is associated with your tank by means of a low-weight hose from the main phase of your scuba diving regulator. It would be best if you pressed the inflator catch, and the air is placed into your BC scuba.  

If you are on a tight budget, then the first thing you need to know about is how chose the best scuba regulator under $300 for budget buyers.

With the manual inflator (or oral inflator), you put air into the BC air bladder by blowing into a mouthpiece on the inflator hose. It would help if you pressed a catch to open up the hose associated with your BC and afterward blow. It is commonly found right beside the force inflator button. 

Deflator and Dump Valves 

As you presumably speculated by the name, these do something contrary to the force inflators; to be specific, let the ventilate of your jump BC.  

It would help if you pressed a catch on the inflator hose to let some circulation into your BC for the manual deflator. The most straightforward approach to let some circulation into is to go upstanding, lift the hose over your head and press the deflator button.  

A BC scuba will normally have at least one dump valves. These are worked by pulling on a string, which, thus, lets ventilate the bladder.  

One dump valve is normally situated on the left shoulder close to where the hose is associated.  

A typical spot for a second dump valve is on the lower base of the BCD. This lets you dump air in the event that you are altered in the water (since air is discharged from the most noteworthy point.)  

My BC has two dump valves, one on the shoulder and one on the back in the lower right corner.  

The deflator discharges air from the air bladder, likewise with the press of a catch. This is the thing that you use when you need to sink further underwater.  

The dump valves are an option in contrast to the deflator; likewise, this let’s freshen up the bladder. The dump valves are generally fitted with a string that you pull to discharge the air. 

Pressure Release Valve 

There is one more valve on a scuba BCD; the pressure release valve. The weight release valve is a security careful step. You don’t control the weight release valve yourself. It normally releases air when it selects that your air bladder is overinflated. 

Scuba BC’s ordinarily also contains one more valve, a pressure release valve. This valve will normally release air from the bladder if the BC is overinflated. 

Weigh Pockets 

Some plunge BC’s utilization of an incorporated weight system. That implies that you put the loads in extraordinarily planned pockets in the BC, so you don’t need to wear a weight belt. They are planned so you can rapidly dispose of the loads (or a large portion of the loads) if there should arise an occurrence of a crisis.  

My BC for scuba diving doesn’t have an incorporated weight system, so I utilize a weight belt. In any case, on my scuba diving excursion, I leased a scuba BC that utilized the coordinated weight system. I cherished it. At the point when my BC goes done, I am getting one that utilizes a weight mix framework (gee, perhaps I won’t hold up that long).  

Not all scuba BCD have weight pockets. The ones that do are said to have a weight coordinated framework. Weight pockets are exactly what the name proposes; pockets inside for conveying loads.  

This is an option for weight belts.  

Weight pockets permit divers to rapidly expel the weight in the event that they have to ascend in a crisis. It is quicker to expel loads from a pocket than it is to evacuate a weight belt. 

Assorted Straps and Cumber bund 

Your scuba diving BC has a cummerbund-like lash that circumvents your stomach area and makes sure about the BC setup. It is genuinely thick and has Velcro that holds the tie together.  

Additionally, a BC has a tie with interlocking clasps on the upper chest and the cummerbund style belt. These clasps are like what you see on movement rucksacks. They secure and hold the BC set up.  

Likewise, numerous BC’s have Velcro tabs that will hold your hoses set up. So, they don’t disrupt everything, and you can generally contact them if need be.  

A BCD is structured like a vest with lashes over the shoulders and around the midriff. The tie around the midsection is known as a cumberbund tie. The lashes are there to make a tight and agreeable fit. Most ties have clasps, catches, or Velcro that are flexible. 

Back Plate 

This is normally a hard bit of plastic on the rear of a diving BC where the tank is put. The tank is then appended to the BC with a nylon belt that has a locking clasp.  

The backplate is the solid bit of plastic or lightweight metal worn on the rear of the diver. This gives the hardware structure yet additionally makes a hindrance between the dive tank and the diver.  

In many sorts, the Backplate is the place the pressurized air tank is appended to. There are lashes, belts, and clasps on the Backplate that join the air tank. 

Extra Pockets 

A BCD is intended for proficient divers who have a bigger number of pockets than, for instance, a travel model. This is to take into account the necessities of every individual diver. 

Numerous models have extra pockets alongside ties or belts. These are for putting away diving gear like a dive blade and so forth. 


Most BC’s will have pockets so you can store your adornments during your diving. Likewise, you will discover rings joined to the front of the BC so you can snare your rigging on or append a different frill (for example, a dive light).  

A few structures additionally have rings or have rings rather than pockets. Like the extra pockets, these are for putting away pieces of scuba gear during diving. When you need to carry diving gear with you, and you have rings, you should protect the apparatus with ties.  

Expelling diving gear from rings takes longer than opening a pocket, so it is smarter to utilize the rings for scuba parts you don’t need to deal with your hands. For instance, join a diving light to a shoulder tallness ring for a clear vision, yet place your dive blade in a pocket, making it simpler to pull out. 


So, there you have it, all the pieces of your BC scuba you never needed to think about.  

Just joking, this is in case you need to be comfortable with your hardware. The scuba BC is a quite low-tech bit of scuba gear, so it’s anything but difficult to get settled with it. 

These ten scuba gear and scuba diving parts names are, for the most part, the fundamental Buoyancy Control System Components. They are the fundamentals for a sheltered dive so acclimate yourself with each capacity and where they are set on your gadget. 

Obviously, further developed diver BCD may have extra parts to them.  

Hopefully, this article helps you clarified all the uses and parts of Buoyancy Control Control System Components for you to comprehend.
